Storage Disk is not visible SOMETIMES

Dear all,
Please I have a problem with my storage card (MMC Card) since I got it, it works good, but sometimes it is not visible and I must restart my PDA2k to relocate it again, could anybody tell me what it may the problem and how may I resolve it...
BTW I have installed many versions of Windows (Helmi and Xplode) and still the same, so I don't think it is a Windows problem
Thanks all for that amazing

Just take card out and in instead of softreset...
I know its not a solution but its faster

Contacts on Card
If you got your card from E-bay or somwhere it might not be a reputable make or a fake? sometimes these cards have shorter contacts and they sometime disconnect, try a different card with longer contacts?
Good Luck

I have the same problem, too. But there's no solution I've known but softreset T_T

I did it before but not useful, I think I will still have this problem...

I've had this when a card was on it's last legs and about to go to silicon heaven. Backup your data!

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.

All Storage Card Files Gone!

I've been using a 6G ScanDisk card for the last 6 months, without any problems. I needed to move some files from the Tilt's internal memory to the Card, and to my surprise there was only a folder named "FilesToBeDeleted" on the Card. I DID NOT CREATE THIS FOLDER! Oh, and by the way the folder was empty!
Checking the storage of the card from the Memory Setting of the PPC, shows about 3 G in use, which is about what I had on it.
Can anyone shed any light on what could have happened? I can re-format the Card....but is it going to loose data again? Is this something that has happened to others?
Thanks for any help,

i have read that this has happened to some people .. not me yet (fingers crossed) don't know what causes this. You could try a recovery software and see if you can get the stuff back.

Can you or anyone suggest a recovery software? Checking the MicroSD on my laptop shows 2.88 GB being used, (and of course 2.78 GB Free) so the data should be there. I have also saved additional data to the card and it works fine.
Just wondering...is there some kind of virus out there that would do this? For all the data to be "hidden" and a new folder to be created....the card just didn't create a folder by itself....

WM a card killer
The same thing happened to my 4GB SD card in Blue Angel (twice ). It seems to me that WM kills allocation table while writing to the card. I tried lots of different soft to recover my card and finally PC Inspector File Recovery did the job. I used card reader and this soft on PC to recover most of my files but the folder and filenames were sometimes messed up. When using PCI FR do not mark to many files to recover/save at the one time because it crashes.
Don't save anything on your card before recovering !

Yup, I used that program too. Recovered "missing files" problems on my previous hw6515 and twice on my TytnII 8GB micro SDdisk.

I've always had that "FilesToBeDeleted" folder too, it's normally hidden and when I delete it it comes back. Nothing special, just some folder the system wants there for some reason apparently, just like the other couple of hidden ones like WMDRM. If you didn't see it before and it now appeared it might have been hidden and the same thing that corrupt the FAT unhid it for some reason.
If you can see 2.88GB used on the PC, are you sure you have also have forced hidden files to display? Your data might be there but just hidden for some reason.
I have also saved additional data to the card and it works fine.

NEVER EVER do that to a media with a problem you might need to recover data from. This might just have ruined your last chance. On the opposite, when possible like on SD cards the first thing you'll want to do is set it as read-only.
When files are deleted, only their reference in the file table are, but the data itself is still present on the media, which allows recovery. But the locations the data is saved on are now marked as free, and anything you'll write on the card now can overwrite it, causing definitive loss.

Thanks a ton!!! The PC Inspector program worked great!! I was able to recover my files Next step, I guess, is to format the card and use it untill it decides to wipe my files out again. Of course my failth is the card will never be the same, and I'll keep a back up of the card also.....actually I was foolishly keeping the back-up for my Tilt on the card...can't trust that method anymore!
Thanks again for all the advise and information. As with all problems, you can always treat them as "learning opportunities", or...... throw the d*** thing out a window!!!!!

Same problem here, just ran into it last night and it's driving me nuts. Is there a way to recover/format the card from within the kaiser? Unfortunately the card reader I have has a max size limitation of 2gb and the card I'm using is 4gb - lame. Any suggestions? Thanks.

Borrow, lend, or steal another card reader.

When I purchased this MicroCard, from ScanDisk, it came with a SD adapter plus a USB Card reader. I threw the USB Card reader in my desk thinking that I would not need this. I found out, by accident, that this USB card reader was the only way I could read the card on a PC. Built in card readers on both my home desk top and laptop would not access the card....
Just passing on this little bit of information, because it never occured to me that I had to use that USB Card reader!

This happened to my girlfriend's phone too. One day some of her programs just didn't work and most everything was gone on her card. Never fixed it, just reformatted card. Scary though.

Yeah, I tried recovering the data using TestDisk, saw some recommendations for it from others with the same problem, but wasn't able to get anywhere with it unfortunately. So in the end all I could do was format it and start over. Ahhh, backups... if I'd only made one.

I think this is a WM issue. Since other devices have the same problem.
here is a quote from another thread
Dutchman said:
I have the same issue with my tytn2.
Sometimes when i play some mp3s from my SD card and the device goes to standby or the program is closed my SD card is suddenly empty.
Removing the SD card and put it back in usually fixes it, sometimes a softreset also works.
So i believe this is a WM issue

I disabled it w/ kaiser tweak. Still i have the issue

Has anyone had the issue while pretty much not ever using Windows Media Player mobile? I was playing DRM'd audio files, is that possibly a common theme?

Could it be Moving PIE Cache?
Happened to me too. 8GB card. Just getting back up and running...wish I had read this last night. I put a bunch of stuff back on the card. Oops. Oh well. I think the common thread may be:
moving your PIE Cache to the SD Card.
Anyone else with this problem also move PIE Cache? Used Memmaid 2.0 to change it.

different in my case, I haven't changed any of the cache settings for PIE.

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.

Another HD7 SD Card Issue

My unbranded htc hd7 has been working perfectly for a couple of weeks now, but recently started to have problems. I switched it on after changing sim cards (which i believe i did perfectly, didnt drop or do anything wrong) and it then says..."storage card cannot be read", not allowing me to go any further. I then try to hard reset the phone, which gets the phone to start up with no problem, but now says it only has 12.5mb of storage available (my sd is 16GB, and is the same one issued with the phone).
I've already counted my losses with the stuff i had on it and i'm willing to format the SD card if it means fixing this issue. But Is there a way to fix this via bootloader or something else that will not void my warranty by me having to physically dissasemble it. Your input is very very much appreciated...

There is an option in Zune which lets you wipe all your data on the sd card:
Settings\Phone\Synchronization Options

Nah that didnt seem to work. When i click on erase, it erases the 12.5mb doesnt seem to find the sd card

Sounds like the SD card has become unseated or corrupt somehow

Let me know if you find a way of formatting the SD card without removing it.

Thanks for your input.
I suspected the same thing, so i removed the back cover and the battery, then used a "caveman fixing tactic" of banging the bottom part of my phone with my hand (didnt want to damage it by hitting it with something harder and again didnt want to open it), and its working. Tried banging it again after that to see if it will stop working again but seems to be fine now.
I know this is just a minor (silly) fix and will go to htc to complain about this fault and see if its loose in there because i've never hit the phone hard before this (besides hitting on my hand of course, which is the first and last time i'm doing it) and nor have i ever dropped it. I still havent ruled out the possibility of a faulty sd card, or an error that seems to be appearing with others after the recent NoDo Update.

hd7 sd card issue
I have exactly same issue, the first time (from new) i turned on it did see the sd card and then i inserted a SIM and did a reset and now it just reports 12.5Mb memory always. I have opened it, voiding warranty to remove the 16gig sandisk card and re-insert it many times but still doesn't see it and yet never reports any error like 'cannot detect sd card'. Next i flashed from O2 to a unbranded ROM (from this forum) and still the same and now doesn't even detects the SIM! Next i tried a new 1gig sandisk card.. still does see it (not sure format is required for wp7).. the orignal 16gig card cannot be read or formated on a PC tried using a pc dos format, low level format, sd format programs but pc never assigns drive letter to it.. so hd7 is scrap unless someone can suggest something to resolve.. i suspect the SD card interface from phone is faulty.. gona try the banging on table method next and hope is smashes to bits put it out of its misery!

Had the same issue with my phone. now stuck in bootloader mode. now have given up and using lg optimus one.

Mine is doing the same thing only showing 12mb even with the stock sd card. Did anyone ever get this fixed?

What version of WP do you guys are on? I noticed after each update, the system seems to grab more space on the card. That said, there is a option in Zune settings to change the available storage via slider, may be you have got that set to 12gb somehow... May be try to change it and c what happens then. I personally don't have this problem, even after modifying my hd7 so I can swap sd cards as needed (hard reset required but kind of useful)
Sent from my HD7 using XDA Windows Phone 7 App

I modded my hd7, too. But I never had this problem.
Did you mod with goldcard method or hspal/rspal???

the sdcard has password on it and can only be read through the phone unless you somehow did something to file system and lost the password than you can fix it.

Fix 12 MB
it fix my sd
enjoy your HD7
