[Q] Screwed up my micro sd card

Well, I tried formatting my 8gb micro sd card that came with my Mytouch4g and now Windows 7 doesn't recognize it. When I insert it into my Mytouch it just says a "blank card" was inserted. I can SEE the size of it when using things like EASEUS or going into disk management but I can't format or anything. I've tried changing the Drive letter and that doesn't work.
Does anyone know what I should do?

Did you just use Windows to format, and did you do a quick format or a full format? Also, what file system did you use?

Sorry about the super late reply. But yes, I used Windows to format, and now im stuck with the problem stated above. I think it was FAT.

Try a different program or os like linux to read/reformat the card.
But its possible that it is defective.
Happened to me that way once.
The card was showing bad performance i thought i could fix it by reformating it, after that i couldn't get it to work again.

If you have installed rom manager, try and format the Sd card from that.

SD card stuck at searching for errors

Hey guys,
I need a lil help! Searched all over but couldnt find a solution. So I was trying to go back to stock. I formatted my SDcard via gparted to FAT32 and rebooted my phone into bootloader. Flashed an SBF with sbf_flash. Now when my phone starts up the SD card is stuck at Preparing SD card searching for errors. If I allow my screen to time out, it gets stuck and pressing the unlock button only gives me flashing lights for the buttons below. I remember some other people having this problem but for me I think it has specifically to do with the SD card because when I remove it and boot everything seems to be fine.
So I tried connecting the phone via USB to my computer. I set the screen to never time out to avoid the black screen and flashing lights thingy. Gparted does not recognize the SDcard, when I select mass storage. Strangely the disk utility in ubuntu recognizes that something is mounted /dev/sdb/ but cannot format or anything and it doesnt show the size of the directory.
In the phone options the card is not mounted so I cannot format via the phone. I dont own a carder reader and where I live itll be really hard to find one. I tried on a windows computer but that didnt recognize the phone at all.
One thing though, I rooted the phone and I can get into adb shell. In adb it shows me an /sdcard/ directory. I was wondering is there any way I can format my SD card using adb?
Thanks for all the help! Cheers!

Never mind, I fixed it. Seems like rooting and logging into adb shell did something to mount it in the phone. Thanks!

Hello guys. I am a first time rooter. I followed this root guide, http://forum.xda-developers.com/showthread.php?t=1016084 all worked and I have tried 3 different roms. The only thing that faile dto work was Gparted, it does not recognise my SD card. I only see my PC HD.
I have tried restarting it, using a different SD card but still the same issue. The whole point of me rooting my desire was so that I could free up space. Is there another simple program I can use to partition my SD?
Thanks
Ryan

I use MiniTool Partition Wizard to partition my SD cards. I like it better than GParted b/c you can format an EXT partition without any data loss on the FAT partition.

Phone wiped micro sd card

i have look in the forums but can't find this exact problem. i have a lg optimus q and it has not only erased the data on 2 of my sd cards but it has also made one not be recognized by my computer at all. The one that is recognized by my computer show a size of 0b, 0 bus, unknown format type and can't be formatted. is there anything i can do to atleasr recover the use of my card?
Edit: just so it is known i have tried formating and partitioning card with SDFormatter, EaseUS Partition, Zero Assumption Recovery, and MiniTool Partition Wizard with no luck.

Try this
Factory reset and what do you mean it deletes does it say something an error or something or why it is deleting?
Press thanks if helped! :good:

i did a factory reset on the phone and it works but the sd cards and all information on them are gone. There is no error message or any warning what so ever. One minute the card is working right and everything is there then the next the phone says the card in blank and when i try to use it on a computer or other phone it still doesn't work.
It has done this twice to me now and ruined both a 32gb and 16gb card. One card is so far gone that my computer won't even recognize it at all now. The one card that is recognized shows a capacity of 0b and an unknown file type.

[Q] Damaged SD card / won't mount - fix?

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?

I did try disk management in windows and the sd drive label wouldnt stay showing long enough for me to get that to work. I dont understand why its able to mount and then shortly after just unmount itself.
Havent tried diskpart, is that a command in CMD?

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"

Ever tried HP USB Disk Storage Format Tool?? Its supposed to work but dont have a card reader to find out ..>(
http://www.softpedia.com/get/System/Hard-Disk-Utils/HP-USB-Disk-Storage-Format-Tool.shtml

I had the same problem with my S3 and tried to recover data from card but nothing worked. Luckily I had most of it backed up. At the end had to get a new card

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.

Android via MTP completely bugged my micro sd card

I was reorganizing files on my computer and sd card. For this i had to delete lots of stuff, etc. MTP was being slow so i decided to remove the micro sd card and use a card reader instead to speed things up.
Something screwed up real bad. Now the card is locked. When i plug in the card reader i can see and read the files, i can delete them, delete everything, but when i plug in the card back again - as if nothing happened.
The native format from windows explorer fails to start. It reports an error: The device, \Device\Harddisk5\DR20, has a bad block.
The diskpart utility fails as well with an error: Cannot zero sectors on disk \\?\PhysicalDrive3. Error code: [email protected]
SD Memory Card Formatter from sdcard org - this program succeeds in format without errors, but when i unplug in insert card - everything is the same
The Disk Wipe - Portable v1.7 program succeeds in format, but again - when reinsert the card - everything is back as it were.
When i reinsert the card in the phone, the phone will initiate a 'check for errors', take a lot of time, won't report any errors found and eventually the thing says card is mounted. But when i attempt to access it - the File Manager hangs and needs to close. If i try to unmount the card, the process take a lot of time so i just unplug it.
What can be done? Never had problems with this card, this thing occurred just now. It's unbelievable.
EDIT: Disk Wipe failed as well - said all NTFS boot sectors unwriteable.

Same here!

I have this exact same problem. 8Gb SD Card on Card reader, something went worng, now the files that are there, never change. I can't put new files, if I delete old ones they come back after un-plug and plug-in again.
I was able to make "something" happen, after a while, I reformatted it in exFAT and then again to FAT32. The Old drive name did change to the new one I've selected, and the files are gone, but now it's completely empty it says all the space 7,50 Gb is free, but I can't access it, nor can I clean the partition table using Diskpart, I get Access Denied (as admin and readonly=no) error and on Event Viewer I get error [email protected]
Anyone? Please? Save our Flash drives? Thanks.

I know this thread is old but it's the first result on Google when searching for the error code, so I'm posting my reply. Someone on Spiceworks linked to this tool. It formatted my broken SD card that had this exact issue, and now I can use the card again like normal.
