SD card corrupted

I have been using a 2GB SanDisk card for about a year with my XDA2i without problems. Until last week when it seems all the data on the card has become corrupt (see attached file). The data looks the same whether the card is read on the XDA or on a card reader. Any way it can be salvaged?

So, no suggestions from anyone. Great stuff...

I have the same problem m8 did u fix it in the end?Mine reads in my magician but not in a pc or my friends phone that i borrowed to do the big storage hack!Also any ideas on how to un write protect an mmc card?
Thanks

write protect? thers a sliding switch at the side of the card to make it write protect.. Is that the one..?

Are you guys using SPB pocket plus & monitoring the SD card as well, with storage card indicator? SD's sometimes are corrupted when proocesses are accessing it @ the sime time.
M

Just a suggestion...but you could try running some data recovery software on the card (such as "don't panic" - many others out there) to see if it will recover the data.
I would also bug it in your pc and run a scan disk on the card, and check "fix error"
It's worth a try, hope this helps

SanDisk 2GB Memory Card Problem

I was using it pretty good and suddenly my memory card appear and disappear when ever i reset my ppc. Now, i cant detect it anymore on my dopod 838 pro.

Pull the card out and pop it in a Normal PC Card reader and see if you can see the contents. For some reason PPC's will occasionally corrupt the formatting of the card to majke it unreadable to it but PC's sometimes can. If you can read it with a PC, then copy the contents off, reformat usign the PC and copy the contents back and try it in the PPC again.

ok will do that. but isnt that dangerous to lose data tat way? also, when i could read the memory card, the folders r there but the files r gone. possible virus?

i can find my memory card on the card reader. i tried formatting it but it gave me an error "Window is unable to complete the format". What is wrong?

Were you able to copy your info off of the card? How were you trying to format it?
Make sure that you DON'T have a window to the card open when trying to format.

HELP ME WITH ADVISE!
My problem is back again. My data at certain folder in the memory card is disappeared but still able to browse the memory card. Then i soft-reset a couple of times and the data comes back. It took the dopod 838 pro to read the memory card very long time b4 able to show the data on the card.
What should i do?

Check the registry key HKEY_LOCAL_MACHINE\System\StorageManager. There are two DWORD values - PNPUnloadDelay and PNPWaitIODelay. If they are not set to 8196 - do that.

its 8196 as posted...

Looks to me like 2 possibilities:
Your SD Card is shot; or
Your phone has lost the plot.
If it reads OK on the PC card reader, the card is probably OK.
I'd try a hard reset of the phone first. (Make sure you have backed up everything first.)
Also, clean the SD slot as best you can to make sure there are no biscuit crumbs or old socks fallen into the hole.

Seems like some problems with this card. You didn't try another one?

[Q] "SD Card mounted as read-only"?

Hi,
I'm posting this issue second time. I have a class 2 SD card with almost 1700mb of ext3 partition. the problem is that my SD turns to read only when accessing some files from my sd card. it says in the notification SD card mounted as a read only and then say "tap" to resolve the card responded unexpectedly.
tapping on it sometimes help if i remove the files that I was trying to access that created the problem. otherwise it mounts it as read only.

Hi, you sure your card is a genuine one? The problems you are having are identical to what I had. Turns out my 32gb card was in fact an 8gb card, and the problem was when capacity was reached it would go to read only. The only way to rectify this was to take the card out, place it in my PC card reader right click on properties of the drive and run the error checking tool. Hope this helps. Got my money back anyway thought £36 was a bit cheap lol! Try writing a large file to the card using your Computer, this should give you an indication if the card is genuine or not.

Card is genuine. I have placed my card several times in my brothers htc hd and formatted it through windows. its almost 8 gb i checked it on windows. last time I deleted a folder which has wiered name as if the folder was corrupted. I deleted that folder n it was running fine again. but its back again.
mine came with telus, so it should be genuine. what does class signify? like i have class 2, what does it mean?

CLass is the speed of read and writes.
I recently had a problen like this it turned out to be a corrupt file in the .secure folder used for apps to sd.

then I guess its because of corrupt files but why is it so often specially when I copy something from windows.

I had this problem once after disconnecting from a Windows PC, simply connect the sd car directly to a computer and run the windows verification tool, it finds the corrupt file and your sd card starts working again

hey i recently had the same problem ,, but i figured it out and this method should work fine...!!
>First of all you should know how this problem has occurred..??,
well the reason is, we all connect the phone to system in usb mass storage mode ,,but while removing we'll only give safely remove in the system and forget to do the same in the phone ,,,trust me this the core for this problem....sd-card cannot be fully unmounted by system ,,, so you have to manually do this by your phone
so if you are using the sense rom ,,after ejecting the disk in the system ,,,in your your phone's notification area
in ''connect to pc'' menu select charging only .....this will completely unmount your memory card .
>if you are using non sense rom ,,"turn off the usb" mass storage
do this every time you connect your phone to the system ..!!!
ok now solution for your problem..
>reboot your phone to recovery mode using rom manager...
>select partition menu
>now select mount usb storage ,,,
>now you have tow options
1. either you backup every thing and format your sd-card (recommended)
or
2.mount your sd-card and check for errors in windows,,,
this should fix your problem ..
remember ,,next time when you are connecting your phone don't direly unplug the the cable..!!

The Class number represents a multiple of 1 MB/s
So if 2 is written on ur SD card then it means that its capable of a read speed of 3MB/s

- Not always true, its happened to me on several occassions when not connected to PC etc... Flickie HD caused mine
If you have a mac the fix is - disk utilities - repair card
Full format I found to be better though

SD card mount problem please help

I've been searching all over for a couple days now and I can't find any solution only people with similar but not exact same problem I'm having. Out of the blue a couple days ago the fat32 partition on my 32GB class10 patriot SD card unmounted and won't mount at all. However the ext4 partition mounts just fine and continues to work as it always has. I also can't plug the card directly into my PC because the adapter that came with the micro SD card appears to not work. My PC doesn't think there is an SD card in it. I tried it with a known good SD card (the 16GB samsung SD card that came with the phone. Which when inserted into the phone mounts and can be used like expected. No new apps where installed or changes made to my phone or the SD card before it stopped working correctly. The same apps and what not have been in use for as long as I have had the 32GB SD card. In fact the currently in use version of CM10.1 has been is use for the last month with no issue regarding the SD card. When I remove the card a notification shows up telling me to insert an SD card. And when I insert the 32GB card the checking SD card notification shows up an a second or two after the SD card is safe to remove notification shows up as if I had told it to unmount the SD card. If I tap on mount SD card in settings the same thing happens. And it also happens after a reboot. CWM can't mount the SD card either. What can I do to fix it so the fat32 partition is usable again?

Have you tried formatting the SD card in recovery?

As I said I can't mount it with CWM either. The card contains the data for my mSecure passwords as that app was forced to the SD card due to JB changes in android so I can't format it until I can recover the data on it. I need a solution to access the data before I can reformat it assuming that it needs to be reformatted. The SD card was supposed to be this fail safe thing and I didn't need to make backups of it as it was the backup storage stuff. So now I'm all freaking out because I can't access it for all the backed up data on top of the data for one critical app that was forced to reside on it. The good news is that only a few apps data is effected by this the bad news is those apps were all very important. I just don't understand why this has happened. And if using a cloud source such as box will be any more secure and safe than using the SD card in light of this; now I don't trust not losing data in the future on a source that was supposed to not have this sort of thing happen.

Maybe the SD card just went bad. Sorry I couldn't be of more help.

No problem, it's a problem no easily solved, and is a long shot finding anyone who will be able to help. I looked at dozens of sites and forum threads and all sorts of other stuff from goggle searches and couldn't find a solution to get it to mount in either the phone or on my PC to recover the data from it and find out for sure if it is a bad card or not. It might still be under warranty. If it's not I'll be ticked considering how much it cost and how little time I've had it.

Try installing Recuva on your PC, if this program doesn't work for you then you might wanna try another more advanced recovery program like R-studio v6 (Shareware) which is easy to use since it's GUI based.
or testdisk-6.14-WIP (Freeware) which includes testdisk_win.exe for partition recovery and photorec_win.exe for files and media recovery, but it's kinda complicated since it's based on Command Prompt or DOS! so you need to google for a guide for how to use it.

Wow I somehow never got notified of this post seeing as I'm just now noticing a reply from months ago. Yes I still can't mount the SD card. I took it out and returned to the stock one that came with my phone. I still have the card as I need to recover the data from it and if not possible wipe it somehow so that I can warranty exchange it. Please do let me know what your solution is so that I can try it and see if it works.

Refresh my memory on what the problem was. This was a while ago lol.

The SD card won't mount in my samsung epic and my windows PCs. This was a sudden without warning signs and with no apparent cause. One moment it was fine and the next moment poof. I was looking for a solution to gain access to the files on it to recover whatever I can and if possible repair the card so that it works again. Assuming that it's not a failure of the card itself. It is within the warranty and well within the life expectancy of it. So I suspect it is not a failure of the card itself. I have the option of using ubuntu or other USB stick bootable options for tools as needed.

SD Card Issues

Hello All,
Two weeks ago I bought a new Samsung MicroSDHC Pro 64GB Class 10. Kinda from the beginning it wasn't working how it should.. I formated it EXT4, exFat and FAT32 but all give the same problem.
For example; I copy a flashable zip on my external sd card, copies just find, but as soon as I try to flash from the external sd card I keep getting an error and the flash failed, almost instantly. If I copy and flash the same file to my internal sd card, it works just fine and no problems what so ever.
I tried formatting it through Sense, GPe and even a USB card reader.. all give me the same issues. I can even make a titanium backup and it seems to work. Tho, as soon as I try to restore from it, it won't find the files from the backup..but when I check the external sd card on my pc (phone connect to pc by htc usb cable) the files are there and it seems the correct size. But when I want to try a batch restore in titanium backup, and I look the phone for backup folders, it finds the foder.. but when I actualy wanna start the batch recovery, it only sees 1/2/3 apps to restore, even tho there are over 70 apps to restore.
I'm at a loss at the moment, I feel like I've tried everything and nothing seemed to work. This is what the error looks like when trying to flash from external sd card:
E:Unable to open zip file.
Error flashing zip '/external_sd/blablabla/blablabla.zip'
Updating partition details
Hope anyone could help me with the issue.
Thanks in advance<3

I've seen in the past that 64gb cards have issues with formatting unless formatted in windows as Fat32 - mine did
As soon as I did that it worked.

Have you checked it to make sure it's not fake? Where did you buy it from & what is the formatted capacity? Should be like 59gbs and change

Got it from a dutch website, through a person, not a company.. it had all legit packages etc, but how can I check to be 100% sure that it's real?
My computer shows it has 62,4GB total capacity.. reading it from card reader. Sounds wrong?

Deffo wrong. Sounds like a fake. Capacity is 64gb. Available is obviously lower after formatting. Legit packages mean nothing - take a look here
