New Transcend 1GB SD card causing TomTom 5.21 to lock up

Hi there,
It looks like newer Transcend cards are not immune to the TomTom lock up issue.
I have an O2 branded XDA2i with PUGS rom etc. It runs TomTom5.21 fine with the first Transcend 1GB card I bought.
When I'm in the car, I have the phone connected to my car kit via bluetooth. When I make a call, TomTom continues to run, but shows the mute symbol. When I hang up the call, TomTom carries on as normal.
I decided to buy another Trancend card as a backup. This time, though whenever I make a call - TomTom locks up. As in other peoples posts, sometimes this can be cured by pulling the card and re-inserting, other times a soft reset is required.
I thought I'd got a faulty card, so bought another with the intention of returning the faulty one.
The new card shows the same problem.
All three cards were bought within two months of each other.
Anybody else seeing issues with new Transcend cards anfd TomTom?
Cheers,
Chris.

Could you have a look to how are your cards format?
32kb in fat32?
May be they are different...
It's interesting!

Hi there,
I used PocketMechanic to reformat the card to the same spec as the working card. Also tried many other combinations.
Dosn't make any difference on either of the two non working cards.
Perhaps my XDA is extra sensitive to power or speed of the card - but the two newer cards are definetly different.
Be warned all of you that think Transcend is the Holy Grail for SD cards.
Chris.

I have lockups using transcend 2gb 150x...tried several different format tools - it didn't help...
i don't know what to do with it...=(
I can't even listen to music because of pauses... I even tried a player which cashes songs into ram.... but what is strange - it didn't help...
but I think thats because of player didn't cash anything but said that did...
because I don't understand how can it stop playing for 1-2 seconds each minute with cash for 5mb or 5 minutes of music... =|

I am experiencing the same problem.
I've bought the 1GB x80 TRANSCEND SD card a little less than a month ago because it was supposed to cure all QTEK2020i problems.
But in fact it hasn't changed ANYthing compared to the LEXAR x32 1GB I was using before.
So, I decided to upgrade my QTEK rom with PUGS rom while taking the risk of voiding the QTEK warranty.
Unfortunatly, it hasn't solved my problems either. It seemed more stable initialy, and has cured GPRS usage problems and brought slighlty better GSM quality, but that's all with my settings.
Someone has reported this week, that moving from SD to MMC has cured his TT5 problems.
I keep my fingers crossed hoping that this one will be the right fix.

I am sorry Ice_mephi but I don't see any solution there, or I've mistunderstood your comments.
I understand that your SD card might have had errors and they got fixed with the StorageTools application, but I don't see any link between this problem and the TT5.21 freezes. Thanks anyway for mentionning this application.
Listening to music out of any SD card has never been a problem for me, and hans't ben reported as being one from polls I've read so far.
Have I mistunderstood anything ?

I've been using the Transcend 80x 1Gb card with Tom Tom 5.21 on my XDAIIi with absolutely no problems at all for at least a month now (including traffic updates via GPRS). I used tha card as supplied, without reformatting etc.

Hello Andy, also including POIS? Or only with the default installation.

Yes - I have POIs installed. It is set to remind me when I am near petrol stations and wi-fi hotspots (which I have set up myself).
I couldn't believe that the type of SD card would solve this, but it did, and I have never had a problem since!

SD? Another users say that the MMC is working better. :?
I have trascend SD 1Gb 80x, without pois it works perfect, but with them I have freezes... :?

From my experience, changing from a LEXAR x32 1GB to a TRANSCEND x80 1GB didn't solve the problem. Other persons mentionned that they got to the same conclusion with latest TRANSCEND SD cards.
Changing the SD formatting seems to have fixed most of TT5 issues with my TRANSCEND card but I haven't got on trip for hours to confirm it.
People who moved from SD to MMC seem to have got rid of any TT5 freezes.

MMC is the way ahead
I've tried all the stuff mentioned here, including getting a transcend sd card, and although it behaved for about an hour, it started freezing and locking regular after that. I now use a 1Gb TwinMOS MMC+ card, and after 400miles yesterday have not had a single problem. Take what you want from this, but my TT5.21 seems to prefer MMC.

MMC.... is the answer
Replaced my Transcend 1Gb & SanDisk Extreme III SD's for MMC and had no more lockups since

Mine solution for lockups of SD card

So... Yesterday I did one thing - and as the result - no lockups while listening to music today...
I have Qtek 2020i and trancsend 150x 2GB SD card.
What I did:
1) formatted my SD card using card reader.
2) than copied music to card with card reader too.
3) inserted card into ppc - tried to listen to music and got lots of lockups....
4) some days ago I found a tool for fixing errors SD card on ppc(format and defragment also): "Storage Tools 2.0". I tried to check sd card with it - and it found lots of errors on sd card.. (there were 2 kind of errors: "lost chains of files" and "2 files pointing same data").. so I runned it and it removed those errors...
5) today I listened to music almost all the day - and wow! there were no lockups!
I do belive that that lockups are caused by some harware fault while reading and writing data to SD card via ppc. but that program somehow corrects errors...don't know how..
but ! be carefull - I tried to format my card using that tool - but after that - my ppc and PC showed me that the card has no free space - I tried to reformat it via card reader and other tools - it didn't help.
but on transcend homepage I found util for correcting "free space issue" (that is that card's known issue i think..) and it saved my card...
and one more advice - when you'll check your cards for errors - set option to correct errors automaticly, or you will get thousands of messages asking fix or not each found error, and aborting checking won't help.. (I waited for 20 minutes after I pressed stop button - than just soft reseted ppc...)...
so here is that util:
http://www.softwinter.com/storagetools.html
you can use it without paying for it as I understood.
use at your own risk anyway...

That sounds like good news Ice.....
Lets see what others have to say, especially with TT5.

Well I still get the occasional TomTom lock up with my bog standard bought in Tesco's 256MB SD card, formatted to FAT32 2kb (about 1 lockup per 3 days, compared to 1 lockup per 30 mins before I switched to PUGS 1.11.162 and reformatted the card), so I just downloaded and tried this with some interesting results...
I analysed my storage card and it told me that there were errors. So I ran repair (manually clicking ok on each error) and I got a few lost file chains, but about 30 "Bad Directory Entry". When it finished, I ran the "Verify" again, and it told me there were still errors. Ran repair again, this time just 3 "Bad Directory Entry" errors.
Upshot, each time I check it with this tool it tells me there are errors, and doesn't seem to be able to fix them. Pocket Mechanic on the other hand tells me that my card is fine and that there are no errors.
Don't know which to believe.

hm...wes there any work with card between checks? if there were some write operations it could cause new errors.. if that util worked from sd card exspecially..
I have no other card to test it myself...but my seems to work fine..
while listening to music I had lockuos about every 5 minutes...it's gone..
now I am going to try installing some programs to card and more music and see what happens...

So I tried to add\remove some data from card - no errors appeared - and no lock ups still...
so now i think that formatting SD card clears only header of a card, and leaves some info on free space - which can cause such trouble when accessing new data....

Used StorageTools to reformat SD as FAT32, 2K cluster size
Downloaded TT5 maps and ran Scan with Repair option but still issues with TT 5.21 lockup!!
Tried with both 1Gb SanDisk Extreme III and 1Gb Transcend 80x

heh =|
btw, you all speak about tomtom lockup, do you have lockups when listening to music? because I never used tomtom - I just had problems with music....

I think the corrupted data on the cards is caused by momentary power losses which the card reader experiences (thanks to a fault in the Alpine hardware), if I remember past discussion on this forum correctly...
Also, is the Transcend SD card an MLC or SLC card? Because as far as I know, SLCs don't suffer from the data problems MLC cards suffer sometimes when used in Alpines.

Chris,
How can you find out if the Transcend SD is MLC or SLC ?
Would upgrading to a later ROM fix the problem?

If you search the forums for the threads discussing MLC Vs. SLC, I think you'll find out your answer.
Basically, I believe the only ways to tell if a card is SLC or MLC are to either have a program which will tell you (I don't know of one myself), or check the manufacturer's web site for technical information... Or ask someone who may know.
I don't believe upgrading the ROM will solve the problem, it's a hardware issue (the card readers are too sensitive to power fluctuations). It was previously assumed that the latest Transcend cards were immune from the problems with some other makes of SD card, but it seems from various user reports that they do indeed suffer - usually randomly - from similar problems.
Another user reported that after switching from SD cards to MMC cards, the problem was alleviated, and he went from experiencing quite a few lockups daily to absolutely no problems at all. Therefore, it may be worth your while sending back the Transcend card and buying an MMC (which you're quite entitled to do if you're a UK resident and you purchased the card recently from a UK retailer, thanks to the Distance Sale of Goods Act).

We're on the same wavelength

I had a 1Gb Sandisk, I had to buy a Transcend 80x 1Gb, and know do you think we have to buy another card (MMC)!!!??
Please QTEK!!!! Solve IT!!!!

Well, if you can't return the item for a refund, you could always flog it on eBay.

I don't think the problem of TomTom lockups is caused by momentary power losses which the card reader experiences as stated by christopherwoods.
The card readers may be too sensitive to power fluctuations, but after doing the following testing, here is below the results I had:
1 - Transcend 2 Go SD card 150X (2Go) with QTEK 2020i using TOMTOM
5.21, but I took out the SIM card of my phone (so no more GSM signal)
I did not suffer any lockups with TOMTOM during many trips
2 - Transcend 2 Go SD card 150X (2Go) with QTEK 2020i using TOMTOM
5.21, but I put back the SIM card in my phone, and here are the
lockups back again.
I noticed that when my phone is searching for GSM signal (when moving from one cell to another, or in weak signal area), then it is precisly the time where TOMTOM lockup. Maybe it is when QTEK2020i search for GSM signal then there is power fluctuations on the card reader of the phone, which result with a lockup of TOMTOM or other applications (as stated by other people).
In this case, christopherwoods would be right.
Anyway, I have moved since more then one week to a Kingston 2Go MMC Plus Card, and I said goodbye to all the lockups problems, it works perfectly, and I'm very happy with my 2020i.

I can't say for sure, I've never experienced any problems like this on my 2i (but I have a fairly old 256mb SD card which JUST fits TT5 and the GB and NL plus maps, my largest SD card I use in my digital camera). All I mentioned in my previous post were things other people either took an educated guess at, or mentioned might be the cause of the problem. It seems that a fair few peoples' bug reports and diagnoses of their problems were quite similar though, which led me to believe that this is probably the cause.
It would fit, if the device needs to draw more power than available to boost the signal strength to handshake with a cell, I'd expect all the other interfaces to suffer as a result, the memory card unfortunately being particularly susceptible (especially with these newest, HUGE memory cards which I can only imagine are really sensitive to voltage change, being so tightly packed into the chip).

I don't think temporary power losses have anything to do with the problems we are facing.
TRANSCEND SD cards as most of FLASH cards assemblers work at 3.3V +/- 10 to 20%. For example the TRANSCEND 1GB x80 SL is given to work between 2.7V and 3.6V.
Also, the problems I have been having were the same with LEXAR 1GB x32 that used to be one of the reference cards for IPAQ2215, behaves the same way the TRANSCEND 1GB x80 does.
And TT5.21 freezes happen when the 2020i is plugged to the cigaret lighter adapter as well as being used on its onw battery.
A problem has been identified with TT5 when changing cell towers, and this might be still be the case even though TT5.21 was supposed to cure it.
I can reproduce the freezes 5min from home when entering a particular area, and changing cell tower migh have something to do with it.
When changing cell-phone tower I think it induces either higher data transfers between the radio module and the processor, or the opposite way keep it in hold for a pretty long time.
When looking at SD or MMC specs, I found out that several revisions of the MMC standard specifications have been released. So, I think the 2020i hardware or firmware version we are using, only supports a certain sets of this MMC/SD standards. The same issue was known on the IPAQ221x serie regarding BlueTooth.That PDA wasn't able to communicate properly with certain BT devices that implemented BT1.2 standard because of its hardware design. Also on that PDA certain SD cards weren't supported properly when running TT2 or 3. I found out at that time that running TT app & sound files out of RAM instead of SD was the cure to problems whatever SD card was used.
Unfortunatly, running TT5 and associated files out of SD or RAM doesn't change anything on the 2020i regarding freezes.
I think the problem is a hardware/firmware issue between cell-phone tower changes and SD card support.
Hope we'll figure out what the real issue is, and have a definitive fix for it.
So far, Bigdede's tip seems to be the one, unless other people than sybaseian have fix their problem when moving to newer ROM updates.

Hmm. Well, my old SD card is a PNY 256Mb, if that helps in diagnosis. I have the occasional problem with TT locking up if I try to load too many POI or display them on the map, you have to be patient with this SD card It's just got quite a slow access rate. That has to be one of the main reasons for this problem... Maybe the CPU just can't keep up with the fastest read/write rates of these new cards when it's having to think about loads of other stuff at the same time? Resulting in momentary data loss or corruption, just like WMP will sometimes stutter or crap out.

The same for me I can reproduce this lockup it in a particular point. But only when I have additional pois activated.
(I have trascend 1Gb 80x)
Without these pois, it works perfectly.

Storage card randomly lost data

Yesterday my girlfriend told me all of a sudden her programs on her storage card stopped working. Well come to find out, it was like everything related to windows on the card was deleted somehow (program files, application data, etc.). She used to have the same card in a flip phone so the folders from that like music and pictures still exist. She hasn't changed anything on her phone, I usually do all that for her, so she wouldn't have done anything in that department.
Anyone heard of this happening before?
Any help would be greatful, I would like to possibly retrieve some files before I reformat the card.
Thanks in advance.

Step one: Buy a SD reader. You can get one on Ebay, Radioshack, etc. Very cheap. 5-25 dollars. I think 25 is even pushing it.
Step two: see if you can retrieve files with reader
Step three: after retrieving said files, format your SD card.

You forgot step four:
don't let girlfriends use technology and don't trust anyone when they say nothing happened
j/k

Very true. She sometimes can be a little thick, but with Windows mobile, who knows what can happen.

I've had the exact same thing happen to me. AT&T Tilt and 6GB Sandisk MicroSD.
File Explorer on the phone shows nothing on the card. Tried reading the card with a card reader on the PC and it also shows the card is blank. However, the Tilt's memory usage program still shows 3GB of memory is used on the card.

Same problem here (few times). Even change the SD card. Maybe something in power managment (kaiser tweak?)

Same problem here - lost a TomTom map just randomly - copied map back on, same files, same path.... still using and extra 1gb....
Good stuff...

Cart corrupting on Kaiser is often a problem, you can use a card reader and the soft R-Studio to try get your stuff back...it worked great for me =)
And after formating your card, try to install the Artemis plugin for Card corruption...=)

I have not heard about this plugin either. Interested!

I have had the same issue having lost tom tom maps pictures etc. I have actually installed the artemis card coruption fix as I had that phone b4 this one & it still has happened to me a few times. I am going to format card one last time & the phone from default & see if this occurs again, as I believe it to be caused due to excess heat from the device but that is only a hunch as each time it has occurred the phone has been red hot prior to this.

Kaiser problem: cannot read storage card

Hi guys,
I have just bought my Tilt 8925. Everything is going fine except the Storage card, the PDA seems not able to read the storage card - Kingston 1G mircoSD.
I tried something like:
- Format the card with my PC and copy some file into the card but when I use File Explorer to find the card, nothing there.
- Check About: Expansion slot: In use
- Check Memory: Total storage card memory: Not installed.
What should I do to make the PDA recognize the card? Any help is much appreciated.

Hi there
Have you tried formatting the card with the PDA instead of the PC? I'm sure Windows Mobile has the setting somewhere (can't think off the top of my head!)
Or, could use 3rd party software like Pocket Mechanic to format it?

I have used Pocket Mechanic but even this software can not find the storage card. I have also tried with a few other cards but the phone can not read either.
What should I do now?

I think you may have a bad storage card. Have you tried another one?
If you try another and it still fails to read the card then it is the Tilt, but try another card first.

If you've tried other cards, then it seems like your phone has a hardware problem with the microSD slot. If you're still under the 1 year warranty, it should be covered.

Had a similar problem with my htc tytn ii (not tilt). Was a day away from booking it in for repairs when I downloaded the official WM6.1 rom. Flashed it and it worked.
Then it worked again. Hard reset didn't do the trick for me.

Thanks all guys
I have tried all solution that I could find from forum, google...But I have to convince myself that it is hardware problem.
I will flash another ROM as last hope.

I have the same problem for about 1month now.. It just stopped reading the mem card.. After a few days, I was able to see the card again in the device's file explorer, but after a few minutes it desappeared (lol)
I needed my tytnII, so I haven't send the device for repairs yet, but I will tomorrow..
I tried everything possible (tried to use other mem cards, flash offcial roms, cooked light roms, etc) but nothing worked.. And my mem card is read by other devices.. I'm also convinced it is a hardware prob..
Just be sure to revert to an official rom and revert the SPL as well, so you don't void the warranty.. You can find the instructions here
Cheers

Hi again
I know this doesn't really help but I had a similar problem with an SD card I bought for a digital camera a while ago (256MB card - biggest there was when I bought it )
I had bought 2 cameras and 2 cards (one for me, one for my dad). His memory card just refused to work in either of the cameras, but worked fine in my Nokia 6600 (told you it was a while ago!). Tried formatting with the PC, phone etc. but nothing worked - had to get a new SD card in the end to replace it

I'm having the same problem. Expansion slot says it's in use, but file explorer shows no card installed. Settings - Memory says no installation. Do you really think flashing a 6.1 rom might help?

Who are you asking?
Does it not see other cards? Even after a hard reset? If you don't have 6.1 then I would say that you are behind the times.

ChumlyEX:
I've read plenty of posts saying that 6.0 is preferred for many situations, stability among them. I just moved to ppc and haven't flashed yet. Do you recommend a specific cooked version?

Very Similar Problem
Hey everyone, before anyone says anything, i researched this pretty good and havent seen an issue similar to mine and this thread is a bit old so i might start a new one.
My problem is that my at&t Tilt is only reading one of my microsd cards,
they are all sandisk, they range from 64mb, 128, 256, (3 different 1 gig) 2 gig and a 4gig sdhc
the tilt reads the 128 with no problems, the others, in About section it shows expansion slot in use, but under Memory it says not installed. does the same for all except the 128mb
i tried them on another tilt, they all work fine
i tried them on my htc wizard, they work fine (with the exception of the 4g sdhc) because wizard has no support for sdhc.
they are all formatted over and over, tried fat32, and fat16 using windows xp, also tried formatting using good old DOS
Scanned them for visruses, none found
I just got the phone so i dont knonw much about the history of the situation, however it had original ship rom, tried reflashing, upgrading to different at&t roms (3 total) tried custom roms.
anyway if anyone reads this and knows something it would be very helpful
Thanks

I had the same problem. My Tytn stopped seeing storage card. I tried another card, same problem. I've flashed the ROM, same problem again. So I guessed it's not the software problem, it is hardware. I gave my device to repair store and they realized that one pin from card reader slot was broken and unable to read card.
That happen because the card I bought was just a slight wider than it should be, it's card manufacturers problem. And when I was putting that card in the slot, it broken one of the pins. It's unable to see it through slot, you need to open device.
They needed to replace whole slot and that cost me about 250 Euros.
****ty thing..
p.s. If you planing to return your phone to repair store and you still got warranty, be sure that you put back original ROM, if you have flashed now. They will not approve you warranty if you have custom ROM

Feedback changed flex cable
ok so this is intressting, and as i was saying in my previous post, there was no problem with the cards (that im aware of) and they worked on my friends tilt, so after some convincing, i got him to agree to let me take his phone apart this morning and swap up the cables so i dont go and buy a flex cable and it turns out its not it. well i took em both apart (without braking anything!!) and i power it up, and guess what, it did the exact same thing!!!!
so a working flex cable did not solve the problem, i tried my cable in his phone, and it worked, read about 7 different micro sd cards!
unless its the motherboard of the phone, or it has to be some software that a hard reset or oem rom wont fix.
there has to be something, i just wish i could find it!

well yesterday i was drunk and dropped my tilt into a toilet full of piss. I took it out to dry, took battery out and shut it off... i forgot to take out my microsd card though.
My tilt is working somewhat fine but its still clearly water damaged. same problem with all of u.. my phoen wont read the microSD card now and i cant load up android which is bull****. so it must be a hardware problem imo

that sux to hear, well i dont belive mine got wet, not that i know of and no signs of water intrusion on the little white water detectors. I am still trying different sdhc drivers but nothing yet

I solved my problem with a new front board and main ribbon. Swapped them out and everything reads perfectly. I paid around $30 or so on ebay for the part.

lucky you!! i did that and it didn't change anything
i even swaped boards, sim card reader, lcd screen, but it has to be something in the main board, i still belive it's a software issue or firmware maybe, something still stuck on that board, i tried it all from hard resets to different roms, spls, radios, reverting back to ship rom, other official roms and nothing. expension slot shows in use, but no storage card with the exception of a couple of different small ones that will show in file explorer, i can install cabs from them but cant really copy anything from device to card or card to device this is so annoying. I even went out and bought a new micro sd and ended up returning it cuz it did the same thing

Final Update
well i was sure that it had something to do with the board of the phone or at least a software or registry issue that was causing this problem, after being 100% sure that it wasnt the flex cable or anything I was lucky to find a motherboard for $26.50 (with shipping) on ebay, so i didn't even hesitate, baught it, swaped the camera (it was the only thing missing) and everything works! i dont know what i'm gona do with the board, but i doubt that im gona give up on figuring out what caused this problem and how to fix it, and i will keep on checking this thread on regular basics

Major sd card problem. We need to fix this.

Well I recently ran into an SD card problem. To find a solution I have searched many forums and Google. None have offered any solution. On my search for answers I have found at least 100+ G1 owners with the same problem. All posting within the last month. The error we are getting is "SD card removed. insert new sd card".
All threads I have come across have suggested to reformat the sd card, repartition, use ADB, cyans recovery image, to fix this problem. None of the above solutions have worked. A majority of the threads the G1 owners were still able to use there sd card with there pc.
Now I know this is in the right section. We need a developer to figure this out. A g1 without a sd card is like a g1 that is bricked. It is horrible not being able to download, play music, shoot pictures, ect.

i ran into this issue on a friends g1. came to find out he dropped it and the sd card would neved get seated correctly in the sd slot. i had to wiggle it a bit before the phone recognized it

Now we are getting some where. This solution didn't help me but might help others in the future when they use the search feature.

I had this problem on one of the roms I was using, maybe Dude's cupcake?
Wipe of the phone fixed it.

I have whiped and upgraded to new roms. My problem began when I entered a command into terminal to fix another problem. After that I whiped and updated to cyans.

I have experienced this 1 time only. When it happened to me, I removed it from the phone completely and checked it in my card reader. It picked up on the PC just fine and everything was still intact, so I knew the card was still good. I rebooted the phone without it and then shut down. Reinserted the card in the phone and booted into recovery. I ran the fix partitions thing and rebooted again. Problem solved. I personally haven't had any other problems since then. I was told on another forum as well that when you flash a new rom or even a new theme to run the partition fix included with cyans recovery. Something to do with apps2sd I think? I have just gotten into that habit and no more issues. Good luck.

I think I might have changed a path on my phone while in terminal and thats what is causing my problem. I can't get cyans recovery because my phone isn't reading the sdcard for me to install it. Also, good post I am sure your solution will help many!

Same for me. With Dude's it wouldn't read my SD card. Wiped, installed Cyanogen's ROM, wiped again, and the problem instantly went away.

Have you tried another SD card in the device? One that you know is good and working in another unit. I screwed up one of my older smaller cards trying to make a Goldcard. It has never worked since.

I tried that a few days ago. No luck there. Im glad were getting this thread going. So far I see a lot of good solutions. Best part about this is all the information is all in one place! If anyone has any input please do tell.

Do you have another card to test out? Have you tried to mount/unmount the card with the phone on? I know if a rom has built in apps2sd the unmount/format option is grayed out. Maybe try to take the card out with the phone on and reboot and then put it back in? Not sure what all to try. I know I was frustrated when mine was doing that as well.

This would happen to me all the time with the camera. I would take two or three photos, then I'd get a message that I need to insert an SD card.
I think the problem was the card. I was using a Patriot 4GB Class 6 card from Fry's. I switched to a Transcend 8GB Class 6 card and have not had any problems since.
It sucks having to buy a new card if you already have one, but $18 for a good quality 8gb card is pretty reasonable.

I have class6 card that does this.. I also have other card that don't .. in the case with my class 6 card it works fine untill I use it for apps to sd, wich in my case renders it useless..
It's word cuz it will load everything fine and run, but then freez up in the middle of use. That's when I know it unmounted itself. Then I'm forced to pull battary out or reboot.. I have truer every methed to fix it with no luck...

Mine is a 4gb c6 card and other than the 1 time, I've had no further problems. I have run A2SD for quite a while even before it was included with different roms.

First comment: Why is this in this section.
Most of these I've seen have been mechanical (poor card seating) - poor card contacts. Swapping the card has always removed the issue for me.

I've had 2 cheaper sd cards go bad. they looked like they worked fine when i put them in a card reader and plugged into a linux box -- but only at first glance.
further inspection revealed bad sectors and damage to the storage. Since i got a nice class 6, it has seemed fine -- i think you get what you pay for a lot of times.
Not to be crass, but this does not belong in this section of the board. Just because one seeks the expertise of developer, doesn't make it ok to post a thread in this forum.
My $.02

I agree, I also think it was cards that were just made bad I guess that's what I get for buying a cheap class 6 transcend from target lol..

Bad SD Card Slot
This happened to me to a week ago after flashing a new Rom, thought I do not think that the flashing had anything to do with it. I tried everything wiggling it , cleaning connection, reformatting. The card worked in other phones and computer but mine. I just think it went bad. Nevertheless after 5 days of getting no where I had T-Mobile send me a replacement

I should add that I also tried 2 new card as well both class 6

this is in the right section. If you havent noticed this a spread problem among many. We have tried other Sd cards. They do not work. This is a internal problem. Thats why its in the developers section. This post will save others from having to post about this same issues if they can find all the answers here. That being said if you have a problem with it maybe you should explain to me why brick threads, ect are ok in this section? There is nothing wrong with my sd card. Just like there isnt anything wrong with the other 5 sd cards I tried.
Google this you will find a lot of people having the same problem.
