I wanted to put some music on my sd card and i turned off my xda and took the sdcard and put it in my usb1.1 6-1 flash reader. Then I noticed that it was filled with odd corrupt files. It looked as if my valid programs on the SD card, mainly those installed using 'choose SD' in activesync, were dead
the sd is 256MB and 3 of the corrupted files in the root of the sd card
claim to be 1.3GB
I didn't format the sdcard when i got it the xda could read it just fine and i copied files from my mem to the SDflash and later on used activesync to install on it. So since this all happen after I put the sdflash in the flash reader. Could it be that causing it ?
This is not on a 2003 ROM so it's not related to any of those issues.
I make sure that before I remove my sd card from the card reader that I right click on the drive in "my computer" and click "eject", this seems to flush any cached or delayed write files and close any open files, give it a try and see if it prevent it happening again.
well i doubt thats the problem because i noticed those corrupted files when i plug'd the sdcard into the PC not when i put it back into the xda
i dident eject the card before taking out the sdcard of the pc
but i did turn off the pc which should result in pretty much the same thing
how do you guys take out the Micro SD card from the phone....do u guys just push the card and it eject or how? I can't seem to find a way to do it? Could my unit/device be bad?? please help thanks
Hey guys
I have Samsung Galaxy S GT-i9003, and I am using the vold.fstab mod for swapping the internal Sd card for the external. I have every thing running fine. But I noticed a strange problem. When I open applications, it seems like the memory card gets mounted in read-only mode, as when I try to use any file explorer to remove files, it cannot delete until I either use root explorer with mounting as R/W mode, or rebooting the device. If so, things get fixed, but after some use, the problem recurs. Besides, I noticed that while the problem is active, the gallary opens empty with a message showing up "No SD card detected". Otherwise, and even with the problem is active, apps open normally and flawlessly, but unable to write files or delete them. Rebooting always fixes the problem.
Any idea why this is happening?
BTW, the card is very new and healthy, and opens perfectly with card reader on windows, and sends and receives files to and from the computer very fast, and it is 16 GB.
Thank you
I solved that problem after months of research... You see, the problem is corruption... The explanation is very very complicated so I am giving you the things you need to do to fix that read only problem...
(Should be done by steps)
1. Put your sdcard in a card reader (recommended) and use chkdsk /r (if you are using windows)... Or simply go to drive properties and go to error checking, check all the boxes and start scanning until finish... Put your card back to the phone... Check if the problem still persisit... If it still persist, do step 2...
2. Backup all files to your computer... Reboot your phone to recovery mode and use the format sdcard option in the mount and storage menu... Restore all data afterwards.. If it still persist, do step 3..
3. Believe it or not, some files in your sdcard are causing a data corruption (This was my issue).. The only fix for this is to find out what files are corrupted... Mostly, the directory that contains these files are from:
sdcard/Android/
sdcard/Gameloft/
sdcard/data/
sdcard/lost.dir/
Do step 2 first... When attempting to restore the files back to your sdcard, do not include this directories... This will more likely solve your problem...
4. Some tweaks such as sdcard speed tweak and other sdcard related tweaks in init.d folder is causing this problem... Try to boot your phone without them and see if it works....
Thank you very much.
I really have some gameloft games installed and believe it or not, the problem is almost always occurring when I open these games !!
I will try your solution and inform you of the results .
BTW, what if the problem is caused by the files of these games? And what if the problem recurred after restoring these files? Is there a permanent fix for that?
Thank you

It seems like it's SD card problem, although it's new!!
I was playing on a game installed on USB Storage, and all of a sudden the game became unresponsive. I then forced reboot the device, and when restarted, SD became unavailable!! I went to "SD and storage" settings and both SD card and USB storage give "Unavailable". Pressing on "Mount SD card" does not work! Formatting is not working!!
Any suggestions guys??

BTW, I remind you that I am using the vold.fstab mod, gingerbread version. I tried to install another SD from my friend's phone that is working fine in his AT&T Galaxy S i9000, but once done, it gives me "USB Storage damaged" !!!!!!!

Seems like I lost my SD card
It opens normally in Windows, and I could back it up. When I delete all files, it gives that they were deleted. But when I eject it and reinsert it, the files are not removed
Neither formatting nor chkdsk in Windows work
GParted gives "Unable to open /dev/... as read-write (file system read-only)"
Any suggestions??

do you mind to post a screen short by command mount in adb shell?
Actually, I took the memory card back to the reseller, and they changed it for another working one. I just dont know why would all of this happen! The card is new, but there were problems preceding its damage, like the aforementioned problem of read-only!!

Actually, during searching for a solution for my problem, some websites suggested the following:
1- if your card gives you that it is read only, try to use micro SD adapter, and put the lock half way between the locking position and the unlocking one, th en try to perform chkdsk, followed by formatting attempt.
2- if formatting has failed, try to use GParted (bootable live disk is available online and can be downloaded).
Your internal SD will subsequently be recovered once the external is recovered, or simply, put a new external SD of whatever size, and you will regain access to your internal SD, and thats supposing you are using vold.fstab mod
Please let us know of the results , hopefully it works with you

So in short my Droid Charge's SD card is screwed up.
I keep getting the message Damaged SD Card message in my notifications and I click it every time to format but then it doesnt do anything. When I try to view my photo gallery it says the sd card is blank or that there is no sd card. It wont let me use the camera because theres no sd card.
I'm rooted running Tweaked 3.0 with the latest FP5 updates after unrooting back to stock in order to get them. Tried to Odin back to stock a few times and then reflashing Tweaked a few times and still the same thing. Did factory/data reset, cache wipe, dalvik wipe a thousand times as well.
I am able to mount the sd card briefly in ClockworkMod Recovery, to view the files on the sd card but then about a minute or less later the sd card seems to unmount itself and becomes unrecognizable. Same for when I connect the phone via USB to my Windows 7 PC. If I pull out the physical sd card from the device, put it back in, hit connect to storage...the PC will recognize it for about a minute basically teasing me, letting me transfer a couple small files...and then unmounts itself and stops being read. Because of this I cant seem to partition the sd card in Windows 7 nor can I get it to complete and Check Disk.
I even bit the bullet while trying to format the sd card in CWM, and then while connect to the PC and I cant even get the card to format...
Obviously I'd prefer to some how save all the files on there before having to format if possible.
Tried searching around the forums but nothing seems to be similar to my problem. The ONLY thing I can come up with for the cause was that I mistakenly flashed the charge.PIT file while flashing Tweaked 3 in Odin. Not sure if thats the cause...
Any help and suggestions would be great. Thanks!!
It sounds to me like it's actually dead, or on its way. Try plugging it into your computer. Make note of the file name (eg F:\) Go to command prompt and type this:
Code:
chkdsk (drive letter with colon and backslash) /f /p
If that doesn't work, your last shot is probably this:
Code:
chkdsk (drive letter with colon and backslash) /r

Can you mount your SD card directly to your PC (i.e., pull it from your phone and use a card reader)? I've had troubles with SD cards in the past and by using a non-phone card reader have been able to save what was on the card or resurrect it back to the point of usability in the phone.

Yeah, I forgot to say be sure to do this with an SD or USB adapter rather than through your phone.

This actually sounds a lot like what can happen to SD cards on some HTC devices if the S-OFF goes bad. The two ways to fix it were to put it in a card reader and reformat it in Windows as FAT32, or there is a way to repartition and reformat it on the phone, but it requires you to know the pull /dev path to the SD card, and I don't know it for this phone.
Still no dice...
Ya I tried using an SD adapter that held the micro SD card, put that directly into my laptop's SD card slot and still had the same experience...it briefly reads and mounts...where i have enough time to dig few a couple folders on there and drag a couple small text docs off...then stops working.
I tried using those command prompts in CMD (chkdsk D:\ /f, chkdsk D:\ /p, and chkdsk D:\ /r) but none of them did the trick. Also the "/p" seems to be an invalid command for chkdsk? I cant seem to get it to partition in any utilities either.
Still cant format it using the adapter either in CMD or the regular Windows 7 interface.
There may also be an issue stemming from the possibility that I think its just acting as read/only. Is there a way to make it read/write? The option doesnt seem to show when i right-click on the briefly mounted sd card for its properties.
My last attempt last night was using Sandisk RescuePRO Deluxe. I started it around midnight and by 7am it was only at roughly 6.5% complete for some reason...arg.
Thoughts?
Did you try the disk management in Windows? Or diskpart?

IIRC you will want to run cmd as administrator (by right clicking on its icon in the start menu). You should also look up some sort of guide if you haven't used it before.
Ughhhh
Still not working Im getting error messages not letting me format. It will select the disk though but then when i try to go further i get "diskpart has encountered an error"

Same issue happened with my ADATA card. I was able to recover the files by wiping the SD Card in TWRP first. Then recovering the boot partions/files using TestDisk. It worked for a while but ultimately, like Lehocki said, I had to get a new card. I was able to return it and get a replacement.
Weird, I had just had the same problem and am also using Tweaked 3.0. Interesting. I also had luck recovering many files using TestDisk,,,however several files were corrupted.
Same problem.

Hello guys I have Sony Xperia e dual (c1605 android 4.1.1). I brought 4gb micro sdhc class 4 card. When I saved musics and images there after some time some musics can't be played and images can't be shown. Also if I save unknown type files on it(java games and android games data and obb files) insted of them appears a lot of files with unknown symbol names. I cant delete them and es file explorer shows that folder size up to 400 gb. Please help me, its my phone problem or sd external card? I hope I explained my problem well.
Hello,
Well, first of all, it's probably a phone problem. Second of all, WHY BUY A CLASS 4? Man, those things are slooooooooooooooow. But I'll try to help! So:
Option 1: try to move every file on the external sd to the internal memory (if you have enough space left), power off your device. Put your sd card back in, and reboot the phone. Then try to move the files you moved earlier to the internal storage, back to the sd card. See if it works.
Option 2(requires pc): power off your device. Important! Otherwise your phone could go to an endless rage of force closes. Believe me, you don't want to have that. It's not harmful nor wil it brick your device. It's just plain annoying.
Remove the sd card, and put it in your card reader, and then into your pc. Backup the content(important!). Then go to your main folder in the computer(probably called: Computer ). Right click on the sc card symbol-> choose Properties, and then search for the tab where it says ''format''. So format it, just keep it FAT32.
Wait for it to be finished, and then move the back-upped content back to the sd. Insert sd card in powered off phone, and reboot. If this doesn't work, I would be really amazed .
Succes, and have a nice day!
Hope I helped!

About 1st method for that reason I don't save anything on my ext card(internal sd.) and it will not work because I try reboot and format by Settings->Storage->Earse SD card. But this happens agaist with other files or same if I redownload/move. If I tern off my mobile or unmount sd card than folder with that files is deleted. Thanks for trying helping me
Hi guys,
I hope this is the right section to post this issue.
Does anyone have a solution to completely erasing data from a sd card, my problem with my sd card is that i am not able to delete files from the card or add any new files. I am able to copy files from the sd card to the pc though. I have tried formating it on various computer operating systems as well as on an android system.
What i get is the format completes but after reconnecting the card to the pc or phone, all the files that were previously on the card have somehow returned and the files are not corrupt or anything because i am able to view images and play music from the sd card. Is there any method I could use or is it time to let the memory card go?
Check for Errors
Try check your SD card for errors on the computer (Mount it first).

Hi JBMorris, i have tried mounting it to the computer still no luck, I used a program called active kill disk to format it and check for errors but the program freezes on the verify and checking for errors section. I think something about the sectors not being readable so I might as well get a new sd card and thanks for the suggestion!

I think you had encrypted it with some device before.... So if you insert in that device and remove encryption...
But if you have factory reset your device and remove encryption key.. Then it will be very hard (may be impossible) to format it or change permissions

You should format your SD card through CMD
To format a memory card from command prompt, follow the below procedure:
Connect the memory card to your PC through card reader.
Click on Start > Run > Type CMD and click on OK.
Assuming the letter of the memory card drive is G.
Now enter this command.
format /q /x G: and press Enter.
Note: Don't forget to replace the letter "G" with your drive letter.

Replacing Card
Hi guys,
Thanks for all the effort, my card doesn't have warranty and I will be replacing it, what I have learned from all this is to stay clear of encryption if you not sure of what it fully entails!
Cheers Fellas!
