Greeting Everyone,
I have a most perplexing problem., for some reason Data keeps randomly deleting from my SD card. I dont know what's causing this but I suspect it happens whenever I run low on USB storage. If that is the reason, why would data be deleted from my SD card because Im low on USB?
If that is the case, how can I prevent this from happening, can I write protect my folders on my SD card? set to read only? AND if I set to read only that means I cannot save data to it either.
Thanks in advance for your assistance.
3 things come to mind ..
1~low storage space
2~corrupted data
3~damaged SD card
And possibly a bad connection on the contact points.
Clean the card contacts with a q-tip and a small amount of rubbing alcohol and reinstall the card.
If the condition persists, then move your files to PC from the card and format the card via PC to FAT32 file structure.
( full format, not the quick method )
Once the card is done, then move your files back to the card.
Also, avoid any repartitioning of the card using apps like rom manager etcetera, as your card can be damaged using these methods.
If the above steps fail, then consider trying another sd card.
Good luck to you ..g
Are you losing a particular "data" file? And if it is just music, did you check with a file explorer to see if it is indeed not there and just not cached by the music app?

I think maybe formatting with FAT32., everything else Ive done. I remember formatting a 16GB card on my PC and never had this issue.

Hey all,
Running the MC2.2 ROM and didn't realise that APP2SD required a reformatting of the card before it could be used, I'd like to start putting this to some good use so as I understand the process to partition the card will require wiping it, is there a way for me to back up the contents of the card? I could obviously copy the entire contents to my PC but where would I copy it back to once the partitioning is finished? Or would it be best to just copy off my media then uninstall/reinstall all apps from the market which will then appear on my card in the appropriate place?
Also is there anything else that needs doing on the phone to enable APP2SD or just having the MC2.2 ROM and inserting a correctly formatted card will do the trick?
Thanks
Russ
hi,
i am using htc incredible s.some days ago i tried to make folders in my 8 gb kingston like for movies,songs etc.but to my surprise when i changed from disk drive option to charge only,i culdnot find any video or could play previous videos using mx video player.i again changed the option to disk drive and saw that there was no folder there and lost dir had all the files.any how i changed the card and bought 32gb kingston.but the problem is same.and once this problem araises,i cannot play any video file except which i have made from its camera.i am so depressed here that i am thinking of selling my phone
i am using the stock rom 2.3.5 gingerbread.plz help me out.
no help from any 1
i figured out the problem.but again a little confused.my sd caed doesnt seem to work properly.how to check and fix the sd card?
I think corrupted or "lost" files go in that folder. Did you unmount the card on the PC before switching from disk storage to charge only on android?

I think You may try to use formating tool from this site www.sdcard.org It usually helps with bigger SD cards.
Worth to try I think.
Connect your phone to your computer in mass storage mode, or preferably use a card reader and copy all your data from SD card to a backup folder. Format your SD card to FAT32 with 32kB cluster size. You can use the normal right click>format option in Windows/Linux/Mac. Uncheck Quick Format (in Windows) and let it do a full format. It'll take around 20-30 minutes for a 16GB card. This will fix any filesystem errors that are causing data loss. Once that's done, copy back all your data as it is back to the SD card. Now your card should work fine for a long time. SD cards tend to get corrupted over time, especially with Android, so doing this once in a while is helpful, whenever your card gives you any problem. I have had this same problem a few times and this fixed it for me.
I have data corruption on sd too but it happens often to data of any type/size and I believe that the corrupted data are moved to LOST.DIR They have no extension and cannot be opened or recognized. So I'm losing apps, photos, videos, anything. My device is an LG P500 and the sd card is a Transcend 4gb class 6.
What cluster size do you recommend for a 4 gb sd? 4kb is the default for its size and I believe that 32kb is too much for such a small card.
So lately i changed my SD card in my device to a Samsung 32GB and when I transfered all my song, later I noticed on the music player that many of the artist are missing.
when I went to check what's going on, I found out many of the folders were been replaced by empty folders that their name starts with the letter "µ".
like for example, the folder "ACDC" became "µCDC".
I tried transferring everything back again facing the same problems with different folders.
I tried doing a factory reset and tried moving the song to the SD card through a card reader, and checked the files were OK before inserting the SD card back into the device and they seemed fined, but after I inserted the SD card I noticed the folders got curropted again.
also before I inserted the SD card there was like 500 MB of free space on the SD card, while after I inserted it suddenly the was like 15 GB of free space, caused by so many data that got deleted.
I don't believe the SD card is damaged, but that my device is messing my things up....
I also remember that I couldn't transfer any video files to the SD Card when it was in the device and could only transfer them into the device's internal memory.
what can I do?
Use the sd formatting tool on your pc to format the card, if still the same then throw it away. It sounds like a fake card, did all the files work while it was in the pc?

All the files have worked while it was on the PC.
I even tried transfering everything via a card reader and everything check allright.
only when I insert it in my device some of the folders get screwd.
Hi guys im having a bit of drama with my sd card and my samsung galaxy tab a 10.1 running android 7.0 unrooted
I first noticed this yesterday as utorrent kept throwing me an error during my download, when i selected the sd card as the download location i noticed it said app data then once i changed the location to internal app data things worked fine.
I tried to delete the failed download but a little error message came up unable to delete so i formated my sd card and it asked for me to select a file to allow write function, i moved my downloads over to the sd card then continued with another download. utorrent has again failed halfway through then upon looking it has actually wiped my sd card completely nothing shows up but apparently i have used 2.8gb but theres no files.
ive been looking around and ive been seeing bits about sd write function being removed after kitkat but i cant seem to find anything about my sd card being wiped or why i cant delete files. Please could someone help me understand whats what or point me in the direction of a thread that explains all this.
thanks in advance

E.g. SanDisk forces some of their usb pen drives into a permanent read-only state when the pen drive detects that it is damaged. Once this happens, this cannot be undone. It is a mechanism to try to save the data. Perhaps your sd card is damaged and something similiar occured? It sounds like a broken/damaged sd card. If you don't need the data on the sd card, you may try to format the sd card with your pc and then again format it with your mobile device. If this fails, it is likely that the sd card is damaged.

Thanks for the reply but tbh ive been really busy getting bits sorted for my holiday i forgot to update my post, turns out its the sd reader in the tablet at fault which is a bit annoying as its the 1st time ive used it in the 8 months ive owned the tablet. Its the 2nd fault to develop with the tablet 1st fault was unresponsive touch screen tight out the box that was repaired now i need to wait until i return from my holiday to have the reader fixed, luckily an OTG and sd reader works like a charm.
Phone the card came out of is a Doogee S68 Pro. I configured the SD card to be internal memory and for the camera app to save pics taken to the SD card. I assumed when the SD card was full the camera would save back to the internal memory but instead it gave an error saying storage full and wouldn't take more photos. There was no option within the camera app to switch the save location to the internal memory so I removed the SD card. This forced the camera to now save to internal memory. BUT. Now when I put the SD card back in it doesn't read and says I need to format the card to use it. Same result if I put the card in different android phones or pug it into a PC. I don't want to format the card because I want the pictures on it.
How can I get the image files off this SD card? I've tried a few file recovery programs without any success. I don't have a linux machine, just a PC, and I have no experience with rooting phones or the like.
Probably card is in raw mode now.
What you mean by saying that you have configured card as an internal storage?

The External SD-card got encrypted as soon as you decided to use it as internal memory. It's no longer readable by any card-reader. IMHO forensic tools are needed to retain the data stored there.

When I pulgged it in the first time it gave two options, use as internal memory or as mass storage device. I choose the internal memory option.

I feared this was the case. I don't understand why the original phone cannot decrypt the card though as it would with a Samsung device. I have sent a support request tot he phone manufacturer so hopefully that bears fruit.

Ok thank you for confirmation. As above card encrypted and furthermore you might have lost all the data of the phone as well as sms , apps, updates basically everything since you choose that option has been storage on ad card, and your internal storage was not used or useless in a different world, access has been denied to it.
Which tools have you tried to recover data?
