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.

[Q] SD Card Error

So I had rooted my phone no problem, been using it for over 2 months now. Again, no problem what so ever. I've just installed CM7 on my mytouch 4g slide and noticed a lot of bugs that still needed to be worked out. so I wiped my phone clean and restored it to an earlier date. After I did that, my sd card has been giving me an error as stated "SD card blank or unsupported filesystem." I've tried formatting it, other SD cards and nothing works. is there anyone that can help?!

i wouldn't know how that happened to your sdcard, but when you say you tried formatting it, how did you format it? i once got an sdcard from an ebay purchase, and it gave me that very same message and was unusable(and formatting it with the phone wasn't working). i made it usable by formatting it with a program called SDFormatter, which i downloaded free for Windows. took a montrously long time for the format, but once it was done, the sdcard was fine.
that sucks that you seem to have lost all your stuff tho?

Try flashing a different ROM. The CM7 we have is still in alpha. Give Team Douche time to work out the bugs.

the problem doesn't seem to be the SD card. because all the data was still there. I tried using another SD card thinking maybe that was the problem but it gave me the same error.
I've already factory reset my phone and its still showing the same problem

Could be dust in the SD card slot or some other debris. Try a little bit of compressed air..

I installed the SDFormatter program you mentioned and formatted my wife's 16gig card. Prior to the format the card wouldn't mount in either of our phones and very sporadically on the PC. Now the card will mount without a problem and is usable again.
Thanks bud,

Formatted my SD card...and now it won't work

My SD was acting a fool (after deleting many ROMs, it still said I had 73MB free). Nothing I did would change it so I decided to format the card. I used Disk Utility (on Mac) and formatted for FAT32. After I did that, my phone said it was in a format it couldn't recognize, so I formatted it from the phone itself. Now, when I enter recovery and attempt to install zip from sdcard, then choose zip from sdcard, it says "E:Can't mount /sdcard". I don't really know what to do, as I formatted it from my phone. I figured that was sure fire but I guess not so much. I tried to find what format I need the SD card in to work properly but I couldn't find anything.
Can someone help me out?

Fat32 is correct for the phone. Do you have a usb reader for the sdhc microsdcard or one of those sdcards that let the microsd card fit in to read it from the pc?

Reboot in recovery, if it says it can't mount it... pop out the sd from your phone and pop it right back in and see if it works. No need to mess with mount points for it either.
Also, did you check if your lost.dir folder is taking up space? Sometimes that thing can get big.

Could have been a bad flash, try to flash it again. I know I had a problem when I bought a new sd card. You can also try to flash it from a different phone. Otherwise, if you have access to a pc, I can tell you how to format it from the command line, which is, in my opinion, better to do if you're having a problem with the quick format that the phone does.

Sounds like what i did one day when i wanted to wipe everything so i did including formatting my SD card through recovery. so it left me with nothing on my phone including a bootable rom! lol. if this is the case with you. Here is what i had to do. Download a new rom to my PC then plug my phone into my PC via USB/ Boot into recovery/ Mount storage/ Mount SD card/ Copy the Rom to SD card then Flash the Rom. Not too sure if this helps, I hope it does, again it sounds like the same problem i had.

Sometimes SD cards break...for some reason they will just stop working, probably due to manufacturing techniques. My old 256mb card went bad, I just tossed it yesterday as a matter of fact. it had no name brand. I still have a 4gb pny that works perfectly and a SanDisk 32gb which also works great. If you do have to get a new SD card, I would recommend getting the highest class you can afford highest out the right now I believe is C10. That will increase your transfer speeds....both of my current cards are class4 and it can take a little bit of time to transfer gigs of data between the phone and computer. If you have any other device that can accept the "card" put it in there and check if it can send and receive data/ format to proper disk size, if not then your card is broken.

Once you go class 10 you don't look back lol

[Q] SD Card Not Writeable?

It seems that my SD card is not writable when inserted. Is this true? I tried to create a new folder on it with root explorer (I am not rooted though) and it said that my device needs to be rooted in order to accomplish that task.
Any ideas?
Jonn

Did you try something like es file explorer? I would try that.

That didn't work either. It says "operation failed".
I actually noticed that it wasn't working playing act raiser and it wasn't saving my position. Moving the ROM to internal storage worked. I then tried to create a folder.

Huh. Just tried a different SD card and that one worked. Weird.

I spoke too soon. After removing the sdcard that worked and putting it back in, it no longer is writeable.

It works again if I pull the card out, restart the shield and put the card back in. Perhaps something up with the mounting process?
It appears that once a card is mounted, if it is removed and re-inserted, it remounts as read only.

It looks like sdcard mounting is messed up. I can't get any of the sdcards i have tried to mount.

Did you go into settings and actually click unmount before removing the SD Card? Many linux systems (android is linux) will mount devices which werent safely removed in read only mode for some bizarre reason.

I tried that as well. It still doesn't work.

when you go to storage under settings, under sd card does it show total space for card. if not maybe you have to format it to NTFS first. thats what I had to do with my new card. also said to do so on shield guide

I did not read the destructions. The destructions have useful information? Where may i find these destructions? I assumed fat32 so that is what my sd is formatted to.

Yes, I formatted it to NTFS before I inserted it. It shows the total space and space available, it just doesn't allow anything to be written to it. I can take it out and put it in a PC and it works correctly. I also have another SD card that I tried and it worked for a few minutes, but I haven't been able to get it to keep working.

sorry I dont know what else to tell you, i first had the same problem like yall when I stuck in a brand new card. nothing I downloaded would go on to card. and it didnt show the amount of space left under the storage menu. Then i found out it need to be formated to NTFS. Once i did that everything started downloaded and showing up on card.

The only memory card I have gotten working (about 1 minute ago) is 512MB and formatted fat32
The card i want to us is a 16gb microsdhc formatted fat32 when this memory card is in my shield it knows it has a memory card but says it has no partitions on it.
I am running testdisk on the sd card and it found 9 partitoins. I will try and clean that up.

To be honest, I've never tried SD card support on the device. So I can't say one way or another. But I'll be looking at it soon enough since I got my first build of CWM for SHIELD waiting for me to debug in the other room once the kids go to bed.

I just tried two different 8GB class 10 transcend cards, an 8GB class 2 generic card and a 256mb sandisk card. I put each card in and copied a file from internal storage to it. Then I removed each of the cards without unmounting and put them back in and proceeded to copy a file to the card again. Every time it worked successfully. I do not even know what format they are in and didn't format them before testing. And, maybe the issue didn't show up because I didn't give it enough time. I am not sure.
Also, I know this is probably a really dumb question but the micro sd slot is spring loaded. You are pushing it in until you hear a good solid click right?

issues
Having issues of my own.
Bought a 64gb sandisk SDXC card for shield. It worked 100% fine in my SGS3 formated for exFat. But not in the shield...
It seems to work somewhat when formated for NTFS. But the file path is really messed up and 1/2 my apps cant see the SD card because of this. It something like (root/storage/sdcard1/....)
2 apps that are basically usless right now due to this are Power amp & FPse.

Android doesn't normally support either exFat or NTFS. The shield may include support for them but if I had a shield I would steer clear anyway and go with what android definitely trusts in FAT32.
Hopefully NVidia will do a firmware update to sort these problems though

[Lenovo A850] SD CARD PROBLEM

Okay so it is been some months that I am using this phone, there is actually no problem with the SD Cards that I have used in the past few months, I bought this new SD Card(that has problem) in the last 1.5 month/s it worked really well and no problem at all. But in the last 2 days, I restarted my phone(changing sim card) turned it back on, then it did not detect the SD Card, I have tried some things like formatting the phone but it did not fix it, I have tried inserting the SD Card into a card reader and insert in my computer it worked, it detected the SD Card, I then tried formatting it from the operating systems formatting tool, I also tried formatting it with SDFormatter V4.0 but it did not fix it. There was a day when my friend tried to edit voldf.stab file from /etc/ since I want it to be like the External Storage will be Internal and vice versa. That is all the informations I can give and is in my mind right now, you can ask more questions regarding this tho thank you so much for reading and I really need help in here. I cannot figure it out.​

My assumptions-
-Faulty SD cage (in case you accidentally slotting in SD card with force)
-Recent change in kernel (I really don't know about kernels, check the other thread)
-Pathogens....( I mean viruses, probably system level that bugs the interference from SD slot to system)
That's my guess. You may try to consult an experienced phone serviceman, or Lenovo Service Center (if your city have one).
