Files in SD card got corrupted

I'm using a 512MB Transcend SD card for a year already and this is the first time I encountered such problem. It suddenly got its files corrupted, names are in symbols like boxes and some files claim to have 1GB of filesize. I can't remember what I did before it happened but im sure everything i was doing then is the usual thing. I didn't even remove it from my XDA. Is there any way to recover them? if none, is there any way to prevent it from occuring in the future? Please help

There is a way to recover them. Get your card into the card reader and start your undelete program (i have a great program if you want).
Seems you have Spb Pocket Plus and you have the storage card indicator active! This indicator seems to cause SD card erasings as many people (including me) tried removing the SD indicator & having no more SD wiping
If thats not true, then try to lock your SD card (the read only switch).
Cheeeers

this is the undelte program:

oh shoots :shock: i already had it reformatted. but thanks so much for the reply Ezzkht
i didn't install Spb Pocket Plus though. And i tried locking the SD card, still the same, filenames are unreadable, just boxes and lines

Sometimes Pocket Hack Master can restore the files as well.

ravelcop, even if you've formatted the SD card, you can still recover the files (the format process does NOT erase the existing data, it just deletes the 1st sector of the media)
Try EasyRecovery Pro (from the link I've sent to you).
Best of luck :wink:

Thanks guys, il try the softwares you recommended.
I hope we could find out what are the causes of this problem so as to prevent it from occuring in the future. Spb Pocket Plus autodetection feature could be one, and it must have other causes as well since i didn't have that software in my XDA

The problem of SD card erasing is cause by having two or more processes accessing the SD card all at the same time. This will cause trouble to the SD card system driver, and hence, will crash your SD!
Thats why Pocket Plus can cause this problem; since the SD card indicator checks the free space of the SD card every X interval, which could occur while having another process accessing the same SD card. :roll:

how to view
I had a sd card that was corrupt as well and I downloaded the file and it said it recovered 64 files. It said your files were recovered successfully. I saved the files in the directory and I can see them there but I can not view them to change them back to a jpeg file. Can someone help?

hi tia,
how did you download the file? i tried clicking that link but i get a page error. i think the link is broken. could you post the file here instead? i'll try to use it and maybe i could help you afterwards. thanks

Can't read SD card

Normally this wouldn't be a problem, as I'm USUALLY good about backing my stuff up but...I hate to say I haven't lately and EVERYTHING is on my SD Card...
Long story short, I just flashed my TP2 back to stock from the SD card. Upon boot-up the phone no longer recognizes the SD. Put it in my computer and it asks me to format. Try my Touch Pro (1) to verify and it can't read it either.
I have a lot of cabs that I didn't get copied to my computer and my only data (contacts, etc) backup on this SD card. Does anyone know what I can do??? I"ve been trying to google it but am getting nowhere....

[Q] SD card not working after 2.2

Sorry for this thread, Ive managed to get it working now

Ok actually Im still having a problem with this, so heres the story
Figured I'd try here for some help here, I have a Bell SGS Vibrant, got tired of waiting for Froyo so I tried a stable build (think its stable ) anyways everything is great overall except now I cant use my external SD card, it says that its write protected, I know that sometimes cards can do that, but I had an idea and was wondering if anyone here could tell me if I was on the right path
I noticed I had a LOST.DIR and .android_secure folders now on my external SD card, from what Ive read its for Mac I believe.... anyways, I noticed the extensions and was wondering if that was the problem, for example looking at my internal SD card its in /mnt/internal_sd/sd directory, so now looking at my external SD its /mnt/internal_sd/external_sd, is that how it should be layed out? I was wondering if I was having problems due to the external SD card being in the internal SD card directory
Model number GT-I9000
Version 2.2
Baseband version I9000XXJP2
Kernel version 2.6.32.9 [email protected] #1
Build number GT-I9000-eng 2.2 MASTER 332 test-keys.332
Just noticed something new when I try to connect the phone in mass storage mode it still says write protected, but when I have it in Kies mode, Windows has it show up as a phone and I can add or delete files that way

From what I know the Lost.dir folder is for files that get corrupted during transfer. At least on the broken flash I have all incomplete transfers go there.
Also its normal that when viewing the contents of your phone through a file explorer on your device that the external SD is in the /sdcard/external_sd/ folder
Now to your problem...have you tried formatting your card?

Ok so I was on the wrong track then, thanks for the info I appreciate it
Ya I only brought up the LOST.DIR cuz I hadnt seen it before in the file system
I have tried formatting it but Win7 is a POS when it comes to formatting it always fails (plus dunno if a FAT format will work properly with Android?), perhaps Ill try it on my Ubuntu laptop and see if I can do it that way, I dont think its a card issue as I have tried another card with the same result, then again its not like 2 cards cant be corrupted
Ill post back here after trying that

Tried formatting it didnt solve the problem, also tried another card that I know isnt corrupted since it works on my wifes BlackBerry, its the same thing, so this is an OS issue
Done lots of Googling but have come up empty
Anyone have any ideas?

[Q] SD Card damaged

Hi guys need a little help here..
So my phone froze up earlier today and seemed that it shutdown, so no problem right, battery pull then reboot... Unfortunately, after rebooting after the "preparing sd card" prompt it said "Damaged SD Card" sd card damaged you.may have to reformat it.
Any ideas..??? I'm quite confused too as my sd-ext is mounting fine and I can go ahead and open it via root explorer, and I'm sure it's fine coz I'm able to open apps that I know are on SD.. but what's up with th fat32..? Sadly I don't have any backups.. any workarounds I can try before reformatting everything..? (Not even sure if reformat will do any good, as it is possible that the card itself got corrupt, though hopefully not)
Suggestions are much appreciated. Thanks!!

Alright so HM you are spot on my friend, tried reading it on the PC and loaded just fine, so I ran chkdsk and selected both options, slapped it back on my phone et voila! Good as new! Thanks for the help, I panicked a little and posted this straight away via mobile app, as it got "damaged" while I was in the office and had no means of checking my SD card via PC.. Again many thanks!
Although 1 question comes in mind, what could've caused this? As of course I would definitely want to prevent this from happening in the future.

if you could not reformat it through usual way, try low level format. work on me all the time when my sd card corrupted. but you have u back up first while u still can cuz when its done, kinda hard to get back up the data.

I would also check for a corrupted file somewhere on your SD card. It will be the one that you were working on before the freeze. If you go and try to delete it, surpirise, it won't delete. I had this same problem and ended up just renaming the folder "bug". Tried to move it over to PC and use Unlocker or File Assassin and no luck. Finally ended up pulling everything off the card and reformating completely.
Check you media and any icons that are grey with an ! in there. Easy fix for that is to go into DCIM/ Thunbnails and delete the top two items that aren't actaully thumbnails. Then go to settings and unmount->remount sdcard to initiate the media scanner. This way you don't have to delete the grey! picture to bring it back into good standing and the picture won't be lost.
Chances are that it happened b/c something interupted whatever you were doing and fritzed out the SD card. Maybe run a sd card and sd-ext check in AOR or MZor too.

Following today's system upgrade my SD card won't mount

I've had my Idol 3 for a couple of weeks now and I just love it . . . so do my 'green' friends! However . . .
My Idol 3 got a major upgrade today, and now the phone won't permit mounting of the SD card . . . home of many apps!
The option under Settings/Storage is not greyed out, it's just that when I tap 'Mount SD card' nothing happens. I'm also getting a continuous notice, i.e. "SD card safe to remove".
The card was not removed either before or after the upgrade, but since I have had the above problem I have done reboots, restarts and hard reboots, and and have removed and replaced the card a couple of times . . . . I'm at a loss on this one!
Does anyone have any suggestions that will help me get the SD card mounted please?
Many thanks!

Just maybe a very strange coincidence here. I have been using the same 32gb sd card since I bought this phone and never had a single issue with the card or the phone (related to the sd card). This morning I checked to see if there was an update, I did not download or install it (since I'm rooted) but man ever since that moment I have been having f-ed up sd card issues. The same types of problems with it randomly unmounting the card and telling me the card is safe to remove, finding the card unmounted and touching the Mount button does nothing and just now I removed the card and my Chromebook is asking if I want to format it... WTF?
All this makes me wonder if Alcatel secretly installed some updates in the background today even though I did not intend for a system update. Hmmm.

I had similar issues with a sandisk microsd.....with it randomly losing everything on the sd....I switched to a samsung microsd and the issue went away so I think it's just very picky with the cards and you should try different manufacturers...also fat32 seemed more reliable than exfat. Samsung and Adata are two I had good results with outside sandisk which I previously considered the gold standard.

Thanks folks.
At this time I don't think it's an SD card issue unless the update corrupted it.
I mean, it was fine before the upgrade guvnor!

Backup the data to pc...format the card in the phone...copy the data back.

Same happened to me on the first OTA update and on this OTA update. I took my SD card out, put in a computer, copied all my files to a desktop folder, re-formatted the SD card, moved all my files from the desktop back on to the SD card once the format was complete and the phone mounted the card no problem. Total PITA and will consume about an hour and a half of your time to do all this. Not sure why this keeps happening on OTA updates, but next time, if Alcatel releases another OTA update, move all your apps back to the phone and remove your SD card prior to initiating an update. Only think I can think of?

Thanks both. Formatting is apparently the only way to go except that my computer wouldn't read the card via the phone.
Soooooo, I have mounted the micro SD in an adapter, and the card is currently being copied to my computer.
I'll let you know how that goes after I've done the format and copied things back.
Maybe just removing the SD card prior to an upgrade will prevent corruptions, or do you think that the upgrade 'needs' the SD card in place?

As the external sd is considered "optional" there is no reason you can't pull it prior to doing an upgrade to eliminate the chance of it getting corrupted.
If you have TWRP flashed and your situation is like mine was you'd find IT could read the card just fine and adb access while in TWRP copied off the data for me so seems related to the actual rom.

The solution
As some of you may have expected, and suggested, I was able to resolve my issue by . . .
1 Backing up the data on the SD card
2 Formatting the SD card
3 Copying my data back to the SD card
However, the .android_secure folder on the SD card was 'locked' by the phone, so I removed it and using Windows Explorer I copied the contents - all my apps that had been moved to the SD card - manually.
If you go this route yourself, your 'favorites' that you dragged to the home screen will be missing, so you'll have to re-do that process. It only takes a matter of minutes.
I want to thank those of you who responded with suggestions that pushed me all the way to the top of my 'success' mountain. The view is great!
Now if only the upgrade hadn't corrupted my SD card in the first place. Grrrrrr!
However, for those that don't realize it, the Idol 3 is a terrific phone that is soon to increase in popularity and recognition.

You might consider installing syncthing and running it on the pc and phone...it uses p2p technology to sync folders between devices....open source version of bittorrent sync. Glad you are back up and running.
