PLEASE help with sd card

Ok so i bought this verbatim microSD 16gb class4...at first it worked fine on my xperia x8...but today it just decided to not be located at all...
On my pc the card is working properly with the card reader and i tried another sd on my x8, and it worked too..but the 16gb still wont be located...i tried everything from formating it to reboot etc...i tried the 16gb one on a x10mini but no luck either...
any recommendations?
oh and the shop said that they cant do anything cause this maybe my fault
Please help...

I had the same problem with 8gb class 4.
I did like what you did.
Finally it didn't work, I returnd it back to the store.
What I understood is: class 4 sd cards are not working on our x8.
because I asked the guys here and they were answering that they have a working sd cards on x8 but with classes like 2,8,10 not 4!

1Fawwaz thnx for your reply
but i could use it for about 2-3 days...and the same happened with an 8gb card but i dont remember of what class..
any ideas anyone?

[UPDATE]
After many experiments i found out that my card was working with thsd card adapter that SE provided once...the one that is like a usb stick...but with a MicroSD to SD adapter,my card wont be located by my pc...

[UPDATE 2]
The card is working fine on my sony ericsson yari.
also i read through the forum that others are using class 4 and its fine..so i cant see why mine wont work...come on guys..you have fixed far more complicated issues...

If the adapter you refer to is really a mSD to SD adapter then your PC would do the right thing(TM). To read a mSD you need a MicroSD to SDHC (<--!!!!) adapter.
SD, SDHC and SDXC are three totally different standards not really compatible to each other.

Then there you have your confirmation that the card is actually working.
If the X8 and X10 is refusing the card, then you may have hit a incompatibility (EDIT: that's why it is important to either straighten it out with the dealership that you can return the card in case it doesn't work or that you can try the card right there in front of the eyes of the shop dude). The only way would be to swap the card with one of another brand (like Kingston or SanDisk ... I wouldn't buy Verbatim crap).
In theory the X8 should be able to accept mSD's up to 32GB.

True, I used a 8GB Kingston Class 4 mSD with my X8 - worked flawlessly.

thnx for your reply..
my card was working in the begining..so im not sure if this is really an incompatibility...

Question is ...
- If you're running a custom ROM ... you tried another one?
- If you're running Stock ... you tried a custom ROM?
Also ... try putting the card into a _working_ mSD adapter and ERASE the partition that's on it. Then "Safely remove" the card reader / card from your PC and put the EMPTY (unpartitioned) card back into the phone. From there you have two options you can try ...
1. Try to partition and format (FAT32) the card in ClockworkMod recovery and see if it works now.
2. Boot up Android and format the card through Android (I think it's "Memory and Storage" in "Settings")

I tried with both stock and GingerDX...same result...im going to try this and post reply in some minutes..

nothing....i tried to partition with CWM..no luck....
I partitioned it with Partition Wizard..no luck again...
pfff...why it just denies to locate it?i was working just fine :S

I take CWM actually recognized the card even at its correct size.
The last thing you can do now is to look through logcat to see if the log holds any hints about why the card isn't recognized/mounted.
You better do that through adb as it's a medium pain in the rear to do that in the Terminal Emulator on the phone.
If you find something that could be related to the issue at hand post it here; maybe the error message carries something that would give a clue.

My sd card is killing me !!!t.t

hi all ,when i 1st used a rom (any rom )there must be a friggin ton of problem ..so when i updated to GDX v21 i expected trouble, so yes it's a little buggy but i fixed / the problem just went away ..so theres just one problem which is a true , but then this problem is just presistant and i can't fix it ...=( so heres's the problem , the sd(8GB class 10 ) in my phone will say it's damage please format , so i did , but then the whole phone restarts without fixing the problem , so i tried 2 more sd card a 2gb class 6 and a 8gb class 10(?) micro SD card they all started fine but then it encountered the same problem , i faced this problem a week ago and i cant fix it , yesterday the memory was abler to be read and then today it says SD card error again.WTF??? i tried factory reset but it's still there use CWM and wipe dalvik and battery stats , no resolve i cant flash cause my sd card is dead , imma using PCC to flash my phone later but is it cause of SD card problem or isit my phone sd card reader is buggy?

-problem -SD card unable to read (says SD card is damaged) tried 3 diff sd card but all same
-well maybe a little off topic but my DSP manager seems to lags the phone badly when i turn on equalizer for speaker

Is your sd card kingston? I have the same problem, and found out that there is a compatibility problem with kingston 8gb.
SE claims to have solved it with an update but this is for stock rom users. So not me. I don't know if anything can be done and if any of our fantastic (slurp slurp) developers could help.

Not able to confirm again ...
There's a 8GB Kingston Class 4 in my X8 which is working perfectly fine since the last 7 months (GDX v021 on Stock Kernel).
However, as there's been another one posting about SD card problems who also has a Class 10 mSD ... I would rather say the phone seems to have a problem with Class 10 Micro SD cards ... given my Class 4 and some Class 6 (if you search the X8 section) work flawlessly.

so i tried 2 more sd card a 2gb class 6 and a 8gb class 10(?)
Click to expand...

The 2GB Class 6 _should_ work, given we have some posts around where people use a Class 6 mSD successfully.
But, as I said above, I would be cautious with Class 10 mSD's as there not only yours which gives trouble.

for some reason my phone is a magnet for trouble ...

I spoke to the guy that sold me the card and he told me to go by the store and try with either a kingston 8gb class 4 or an apacer 16gb class10 (that's what he has in store). I guess i'll try the kingston but i'll be away for a week so I'll have answers next week.

Same here mate. Perhaps we shouls start a club.

haha yea...we are really poor souls =(
damn it i tried my sister's sd card ( just to confirm my problem ) i connect it to pc and all is fine ...then i click turn off usb storage and it says blank sd card ...i guess i cant confirm it's the hardware problem

Just as a related note now that I checked back...
The other guy who had about the same SD card problems was using a Verbatim 16GB Class 4. Seems as the X8/W8 is somewhat picky when it comes to the brand (manufacturer) of a SD card and the related class.
As I wrote in that post - either try the card in your phone right there in the shop (if the clerk agrees to it) or strike a deal that you can return the card in case you have severe troubles due to compatibility issues.

as always thanks BJ! you helped me so many times! so yeah i called my dad to send it to the repairman but i doubt it's the sd card problem since the other 2 i tried also failed to read ...it could initially until i restart the phone or connect it to usb then it will get the warning..i suspect its the hardware problem

Bro, im having the same problem with my 16g transcend sdcard, it hangs during restart and i have to takeout the battery and restart several times to get it up again, its so annoying. ive been searching the web for solutions but haven't really found anything concrete. will let u know if i get an info.

weird. Though I've had the problem you mentioned I never lost my SD card. It always would recognise if I inserted after the phone finished booting completely. Also I was able to format SD card from the phone itself. Now I've jumped to stock and never actually faced any problems

is it possible to insert the sdcard while the phone is on, does it support hotswap or wont it course any damage??

i think there is some problem with the hardware itself my 8gb class 6 card got corrupted after a month's use. .... now using 16 gb class 4, working fine now
Sent from my MagnumHD using Tapatalk

Can't say something wrong with the hardware, using 32GB Class 4 card since a month and am on Bumblebee 101-3 and not a problem, no reboots, no sdcard corruption, I think a lot depends on the ROM also, even whyzee is on stock with 32GB card as I understand, so there's nothing wrong with the hardware AFAIK

Donno guys i think their is some problem with the hardware of the mobile as the same card work pretty fine on my frinds galaxy s so i suppose their is sum problem with hardware
will visit spice service center and wud try to check if they can solve the problem will let u all know if service center ppl r able solve the problem...:/

finally the problem is solved AFAIK aftr giving my mob 2 service center they said tat it had sum software problem which they were able 2 identify nd solve
Thus for as per me it ws a software problem and not a hardware problem...

[Q] Memory Card Board and Wifi Issue

I'm fairly new to the hd7 & it seem windows phone phone got my attention back. love the ui. But two main issue bug me.
1. Memory card
- how do you know the memory card reader/board is working properly? i can't upgrade from 8 to 16gb. my 16gb is sandisk class 4. if i go into bootloader mode, with the memory card - it will read 15XXXGB, with no memory card - it read sd none. But if i format with 16gb inside it wont boot past htc logo. any insight?
2.Wifi
- When the phone is using stock rom, Pre-NoDo, i had no problem connecting my home wifi. but after using custom rom, nextgen v3.4 - Mango, i cannot connect to my wifi. Any idea to solve this? is it by changing my router channel?

WRONG at all!!!
1. Memory card
- how do you know the memory card reader/board is working properly? i can't upgrade from 8 to 16gb. my 16gb is sandisk class 4. if i go into bootloader mode, with the memory card - it will read 15XXXGB, with no memory card - it read sd none. But if i format with 16gb inside it wont boot past htc logo. any insight?
YOU NEVER FORMAT THE CARD!!! windows will do it! 15XXXGB is the right capacity, 16GB. if you formated the card you must do a HARD RESET to make the phone work again... the card gets locked, remember that...
2.Wifi
- When the phone is using stock rom, Pre-NoDo, i had no problem connecting my home wifi. but after using custom rom, nextgen v3.4 - Mango, i cannot connect to my wifi. Any idea to solve this? is it by changing my router channel?
USE another ROM like Dynamics v2.0 or Deepshining v8.

Duhh!! i know that once u put a new memory card inside the phone, i need to hard reset it!! the problem is that with the new memory card, it won't boot past HTC screen. And Also know that 15XXXGB is the right capacity! what im trying to ask is that bootloader recognize my new mmc but it wont boot, so is it the mmc or the hardware?
On using another rom, i'll try it out.

Master 64 GB MicroSD SDXC unable to format/delete files

Hey guys,
Im new to the forum but ive been following quietly for a while. I thought id make my first post, a new thread because ive been having an issue which i dont know is common or not but has been killing me for the past 4 days and i havent been able to find a solution.
BASICALLY,
My MicroSD 64GB (Master UHS-1 Class 10) has all of a sudden decided not to work on me and here is the problem.
First let me establish a few things.
-> MicroSD reads on any computer (im running mac)
-> MicroSD was formatted on my Xperia Z and has been working for the last 3 weeks
-> I have ejected the MicroSD several times without properly unmounting it from the phone (being honest)
-> Files can be read and copied onto the computer
-> Files can be copied onto the MicroSD but once ejected from the computer and reinserted, the files disappear. Its as if the files that are existing on the MicroSD are locked there forever.
-> Files can be deleted and do appear to have been deleted, however once the MicroSD is reinserted into the computer, (Via usb or SD reader), the files just appear again.
Problems:
-> I am trying to format the MicroSD using Disk Utlilty on Mac but to no avail. i have tried every single option and i have even used SD formatter 3.1 which is a third party program. On mac, all i get is an error saying "Mac OSX was unable to repair the disk" -"you can still open or copy files on the disk, but you cant save changes to files on the disk. Back up the disk and reformat as soon as you can."
-> windows gives me the same error. in windows format. I can do exactly the same i.e copy and paste files onto the MicroSD which disappear, i can delete files which reappear and when i attempt to format using even MS-DOS's "DiskPart" utility, which is supposed to be epic, it still does not work..
I just want to reformat the disk and kill everything on it and return it back to normal.
Ive looked at so many searches and read so many web pages, forums, blogs, everything but i could not find a solid solution. Nothing Works.
MY FINAL PROBLEM!!
Once the Micro SD is placed into the Xperia Z, a message pops up saying "preparing micro SD card.. Checking Errors" This message DOES NOT disappear for hours. ive had it on for half a day and it drained my battery to 26% before i realised that it was killing my battery. it was on standby aswell. I have an old 2GB microsd which i used and the message pops up for about 1 second before it disappears.
This is my problem. I cant use the MicroSD on my Xperia Z anymore. The phone just wont read it. It will prepare it for the next century.
If anyone has any suggestions to how i can get these haunted files off my MicroSD and get it back in working order id really appreciate your help!!
Thanks!!

FAT32, NTFS or exFAT?
Running stock or rooted?
I'm running third party software (paragon), and using NTFS.
17gb bluray movie worked without stuttering, and overall seems stable.
I'm rooted.

Thanks benziii for your reply!
My Xperia Z is rooted and with unlocked bootloader. I think it may have something to do with corrupted files? because of removing the MicroSD without unmounting it all the time perhaps? or i really dont know.
By the way its formatted as MS-DOS (FAT) at the moment =/ cant seem to do anything still. or change it.
Tired formatting in different format with no luck
& im trying to get access to a windows computer atm because i find there are many more third party apps on windows than there is on mac.

My Xperia Z is unlocked and rooted and I am using Sandisk 64gb class 10 sd card and no problems. But its just me! :laugh:

If I were to guess I'd say that the card has been corrupted. It may work with a low level format, or it may not.

1. Removing the card without unmounting it is seriously asking for problems.
2. My Xperia Z documentation says it supports up to 32gb cards. i.e. not 64gb.

Perhaps, but it's doubtful they can do anything you can't do on your Mac or Linux.
On OS X, you can run the following two items from the terminal as root:
1. fdisk
2. newfs ((I assume you want "dos" or "exfat" file system types).
Just, you know, make sure you get the drive right and don't nuke your Mac's hard drive by accident!

I thought max size was 32gb also

Officially it is, but I've seen 64gb cards referenced as working many times. I think it's just a matter of the phone not working to SDXC specifications. Though that's hardly a good reason, as everything else on the phone is first class...

Everyday is a learning day.

It seems your SD card is dead My SXZ broke one SD card (32GB Transcend Ultimate, 10 class) in the first week of using - now it is recognized as 1 GB unknown disk with RAW filesystem. So I had to buy new one (32 GB Sandisk Ultra, 10 class).
My phone just loses SD sometimes and doesn't recognize it till restart. Before installing .434 firmware update I met this problem very often. Now (after installing .434) I meet it sometimes when open stock Camera app. I think that is firmware bug, so waiting for next updates.

I was doing some research and realised that before a MicroSD card dies, it will write protect the data before the MSD card dies so that you can back up any data. you can delete files and copy files but they will autodelete themselves after the card is remounted. thats exactly the problem that i have.. oh well thanks guys. i sent the card back for replacement!! hopefully next one i wont screw over too.
Lesson learnt. never eject sd card without unmounting on phone first!! thanks guys!

Interesting.
I bought a 32GB Transcend class10 MicroSD card from Amazon at the same time as I ordered my Xperia Z.
I did manage to copy around 10Gb of music to it, using Sony Bridge For Mac before it was suddenly 'disconnected' part way through the copy process (I was filling it to 25Gb with music from an iTunes Playlist).
After that I tried it in the Mac directly and a Windows laptop, neither of which would write to the MicroSD card, some of the files could be read, but not many. While SDFormatter claimed to have formatted the card, the files (or their names at least) were still visible, further attempts at formatting the card (with SDFormatter) claimed it was write protected.
Putting it directly into the Xperia Z would cause it to reboot after 2-3 minutes.
I returned the card to Amazon. If it had worked on my Mac (or laptop) I might have kept it, but working on nothing made it useless.
I am currently using an old 8Gb MicroSD card that came with (I think...) the Sony Arc I had a few years back and it seems to work perfectly. I'm loath to buy another 32Gb card to find that it doesn't work.
I assume there is no reason why the Xperia Z shouldn't work with a 32Gb MicroSD card? Do I need to ensure that I get a different class of card, or is a class 10 card suitable? Is it just not compatible with the Transcend card?
Any suggestions you have will be most helpful.

same thing happens to me! files remove and reappear ! "chkdsk /f command" in windows shows that one of my files is cross-linked! here is the message:
\App\install\.goutputstream-5JN7ZW is cross-linked on allocation unit 1181239.
i i tried formatting with windows paragon linux (fdisk,mkfs.msdos,gparted,testdisk...)even i ran windows 98 and ran scandisk for fixing cross-link issue ! but till now no luck.
can anyone help me with this
thanks in advance!

in my opinion there is no way to repair this, just throw it in trashbin.. ive tryd almost all..

I'm in the middle of an RMA with SanDisk right now. It seems that once the sd decides to be read only to protect itself, it's done. Replacement is the only option.
