I was just using my phone and then I clicked on an app that i had on my sd card and said that it couldnt be found, then it said that i had a blank sd card and that it needed to be formatted. I tried everything; pulling the battery, mounting, remounting, putting it in and out, tried to mount in recovery, tried to format in recovery...... NOTHING WORKED! So then i tried to plug it in on my computer (windows 7) and it wouldnt mount, so i couldnt format it.... Is there ANYTHING I can do!?!?!!?!? someone please help me cause it is a 16gb sd card and all i have left is a 2gb one... HA that wont work for me. Any help is appreciated!!

Pull sd out of phone and use a card reader to see if it can be read from the pc. If you can read it with the pc, copy all your files to the pc and then format the sd fat32. Once formated put the files back on the sd and put it back in the phone and see if it works then.

If ur phone has a recovery mount usn on phone recovery. Then scan the card with a data recovery tool. Its worked for me in the past

have you ever pulled the SD card out of a device before Unmounted it? Sounds like the the chip inside is dead. There are some places that you can take it to and they can pull the info off of it. its not cheap but they do exist. It all depends on if you really want the info off of it or not.

Have you tried "SD Card Tester" from the Market, Or H2testw 1.4 for the PC?

Is it formated fat32? I would use a pc to backup the files on the sd, and then format it fat32 with windows, and then copy the files back.

I have had to do this before and it normally fixes the problem. does your phone see other sd cards or do you only have the one?

One thing to also considered is that when using your SD Card through your computer make sure to 'safely eject' the device before unmounting your SD card, or it can lead to potential errors.
Glad to hear you got it fixed though.

[Q] Flashed to CM10M1 now having SD problems

I just flashed to CM10M1 and it now tells me that my SD is damaged. I have tried to format it using the phone but the unmounting seems to be taking really long. I have already tried formatting it on my PC, which works, as well as transferring files over, which also works, but when I put it into my phone i comes up with the same error. It is a SanDisk 64GB Mobile Ultra MicroSDXC Class 10. Any help?

I've heard some people had a problem after flashing CM10 with backups done with ROM manager. They said deleting the backups solved it, which doesn't really make sense if you've already formatted the card on your computer, but maybe it'll lead you in the right direction.

What format are you running? I think it has a problem with exFAT format.

Running exfat, will try reformatting to NTFS and will get back to you

Try FAT32. It worked for me. It does say ready to be removed in your storage settings but you should also be able to see the external SD card. Use Solid Explorer and see if you can see the external SD.

SD card problem.

Hi i have 2 sdcards one 16GB class 4 and one 64GB class 10. When i use the 64GB sdcard to install roms, it always shows installation aborted. I am only able to install roms using my 16Gb sdcard.
1) Is this a bug in the rom?
2) And anyways to solve this problem?

BUMP

You may be better off posting this in the thread of the roms you're trying to install.
I may be wrong but aren't some kernels limited to using fat/fat32 etc?
Or of course your 64er could be going faulty?

I've had this problem multiple times with multiple Samsung phones. At this point, I'm pretty sure it's the hardware of the phone, not your SD card, ROM, or anything else. I've went through many SD cards thinking they were defective when they were not.

I mean your sd card works when you are on a samsung rom doesn't it? it is just while being in the recovery that it won't get recognized or did i misunderstand you?

What you could try (even though I don't know how Android can handle this) is to create two partitions with each 32gb on your 64gb sdcard and see whether this works or not. Other than that I don't have too many ideas left :/

you can either do it with windows (Start > Control Panel > System and Maintenance > Administrative Tools > Create and Format Hard Disk Partitions > Disk Management) or with a tool like paragon partition manager (isn't free so you'd have to search for a freeware alternative) and there you shrink your 64gb fat 32 partition to a 32gb fat32 partition and create a new partition on the remaining 32gb of unallocated space also with fat32.
your pc will recognize your sdcard as if there were two. Now that i think of it, I really am not sure whether android will recognize your 64gb or better both 32gb partitions on your phone or if Android will say that you sdcard is corrupted.
If you do that and android suggests to format your sdcard DON'T DO IT ON ANDROID. I got myself some fried sdcards there. So if it doesn't work out you can delete one of the 32gb partitions and enlarge the other again to 64gb but do that from your pc.
You'll need a card reader or usb adapter or something. It won't work with the sdcard inserted in your phone as Android now uses mtp rather than ums and you can't perform those tasks from windows with mtp.

Hmm ill give it a try later. Right now im guessing that my recovery does not support the sdcard. Im currently on CWM TOUCH 6.0.3.1. And looking for a rom with good battery life.

Guys I truly don't mean to be a stick in the mud about this, but you can search XDA and Google about this issue. A lot of people are having this exact same issue. That's why I said a 64 may or may not work with other brands, but the Samsung cards seem to always work like their suppose to (given they aren't defective). There are a few other threads about this on the forums as well. If you do by chance get it working please do share, and perhaps PM a mod and see if you can post a guide on it.

Note 2 has problems with some 64Gb card due to (here: my speculation) bad power supply and stabilization.
Kingston 64/10 makes my Note 2 unhappy.
Sandisk 64/U1 more or less stable with FAT32 but makes instability issues with exFAT.
Sandisk 32/10 and Kingston 32/10 are fully OK with FAT32.

Suddenly Getting SD Card Unexpectedly Removed Error

Been working fine for over a month now all of a sudden the SD card appears to be randomly mounting/unmounting itself and has become unreadable on my phone.
I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.
PS It's a genuine Transcend Premium 300x 64GB bought from MyMemory.

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know

I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

I have been through many a Samsung phones and always had corrupt sd cards in exfat. One day I saw a thread that said convert to fat32 and have never had a problem since.

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.

I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..

when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
