I have a small 4gb microSD card that i had from my old phone and have been using it on the Atrix. I want to get a bigger one but seeing as I have this one now I wanted to format it and use it for backups, etc. It's been working find in my Atrix until just now. I formatted it using the Settings -> Storage -> Format SD card option. Now it will no longer mount properly. I have rebooted the phone a few times, removed the SD card and reinserted it, etc. It recognizes the card and says "Preparing SD card. Checking for errors." in the notification area. But it never completes that and mounts it.
Just now it said "Damaged SD card. SD card damaged. You may have to reformat it." So i tried again to reformat using the phone, and it still will not correctly mount. I'll try some more things, but wondering if anyone else has had this happen or knows of a solution. Thank you.
Problem solved myself. lol. I placed the card in my laptop and saw it was a mess of garbage files. Weird. So I formatted it on windows, then put it back in my Atrix, and all is well. heh.
My external SD card was working fine, had about 16Gb of Music on it. Tonight it has stopped working and is coming up with an error saying "SD card blank or has unsupported file" (I assume it means file system).
I put it into a converter and plugged into PC, Windows reported that SD card also had unsupported file system and asked to format it.
Is there a way to fix this? I really don't want to format the card and then copy all that music back on
Happened to me twice.You can try recuva to find files.
Sent from my GT-I9100 using XDA App
Same here mate. I had a **** load of pics and music. I couldnt find a way around it so....i had to format the SD card...so painful
looks like an iphone but powered by android baby!!!!
Happened to me about 3 months ago, was changing from Checkrom to Krinyo's SlimRom. No apps on my ext SD.
No idea why/how/what happened, but I'd made a backup my SD to my pc. You guys didn't.

Hey guys, I'm gonna try to explain this in most detail. Yesterday spontaneously my External MicroSD card couldn't be detected by my phone(Vibrant SGH-T959). First I thought a simple reboot would work although it failed. Second I have tried unmounting the SD card, and putting it back in and also didn't work. I decided to switch from my JellyBean 4.1.1 ROM back to Schimera v2.2 ICS. I thought the rom was causing the problem, although the problem continued on ICS. I have tried turning my phone off, taking the SD card and all of those combinations and none of them worked. I tried turning on and off USB debugging mode which didn't fix the problem either. I tried using the Computer Management to see if it detected at least my SD card and it didn't. The only way my SD card was actually red when I used a MicroSD adapter. I formatted the card from there and tried all of the solutions again and nothing worked aswell. So now I know that the SD card is working fine but just none being detected by phone or through the USB cable. So I decided to go into my settings > storage to find that my internal storage is only 1.85GB, my model is the 16GB version and I checked previously before. As I scroll down I realize there is something called USB Storage right underneath it and it says 12.67GB which is supposed to be the amount for the Internal SD card. This part is why I'm horribly confused. Also underneath that there is the SD Card and it only displays one button which says Mount SD Card which is disabled when I put the SD card in or out. I tried the option on top for Erase SD Card and it didn't work either. I looked through quite a few threads on this forum trying the ways I mentioned in this thread and they didn't work. Any help is highly appreciated. Thank you
*NEW* I just installed DoubleTwist from the android Play market and when I went into settings and tapped on storage this is what came up: Internal (0.0GB) Memory Card (12.8GB) For one, my phone has 16GB internal storage, My memory card is only 8 GB. *NEW*
*NEW TEST* I tried putting my microSD card into my sister device and it worked on hers, I tried putting her SD card into my vibrant and it didn't read it either!*NEW TEST*
Your 1.85 is the part of your 16gb Vibrant that us partitioned for apps. The 12.67gb is your internal SD. And your other setting should be your external SD or emmc card.
When you say you can't see your external are you looking at external and it isn't showing anything with a file explorer? Try looking in your emmc folder. Have you tried another card?

Thanks for clearing that up for me, and I can't access my card in the file explorer either. I don't have an EMMC folder and I tried going into recovery to "mount emmc" but it just gave me an error. Also I did not try another card because I don't have one lying around.. Plus when I rebooted my phone in the notification menu it says Checking SD card for errors and then it disappears. There is no message once that one leaves.

I have a 64gb Sandisk Ultra SDXC card formatted in exFAT. I had been using the card in my NOTE 2 with no issues. I normally keep all of my movies, music, emulators, and ROMs on it so I can keep space free on my phone. This morning I got my phone setup the way that I wanted it and I decided to install the SD card into the new phone. Everything seemed to go okay, I got a message telling me that it was preparing the card, but after the message disappeared, the SD card was not recognized. There were no error messages regarding the card, it simply did not show any additional storage on the phone and all options regarding the card with exception to "Mount SD Card" and "Format SD Card" were not accessible.
I took ejected the card and formatted it to NTFS to see if that would make a difference and when I reinserted it into the (M8), it recognized it as a blank SD card that was not in the proper format. It prompted me to format the card while still installed in the device, which it did without error. After the format was complete I received the same "Preparing SD Card" message that I received before, but after the message disappeared, the card still didn't show up as additional storage.
Through a root browser I have the option to enter extSD, but nothing I put on the card is there. I then took the card back out, installed it into my Note 2 and it worked with no problems at all. Finally I ejected the card, reinstalled it in the (M8) again, it gives me the same prompt as before, but after the message disappears the additional storage does not show up and all options with exception to "Mount SD Card" and "Format SD Card" are inaccessible once again.
I have tried the fix found here: http://forum.xda-developers.com/showthread.php?t=2700310 to no avail.
Does anyone have any ideas why this might be happening and is there any way that I can solve the problem?
Phone Info:
- HTC One (M8) 32gb
- Unlocked Bootloader
- Rooted Stock KitKat 4.4.2
- Jmz WP Removal Custom Kernel
If you have a USB card reader, try formatting the card as FAT32 with your computer.
I believe most cards come pre-formatted as FAT32 by default. I've always just put the cards in my Android devices without any formatting, and they work just fine.
Not sure why the device's default format didn't work, but possibly formatting on a computer will get it working.
It's possible that SD may be dying.
I had a 32gb card that a friend left with me to fill with movies/etc, but since I wasnt going to see them for a while, I decided to use it with my old LGOG. Not 3 days later, I get what you described, and now the card isnt even seen by Windows.
Even with formatting the card, it would work again for a few minutes, but as soon as I tried copying more than ~3 gigs, the card would go corrupt again.
SD cards dont last forever yo.

I just tried it out a few minutes ago. I don't know why, but it's working perfectly fine in Windows, a Note 2, S3, and an S5. I have no idea what's going on, but no matter what I try, nothing makes it work on this phone.

I was able to get the card formatted form exFAT to FAT32 and it looked like it was going to work, same with NTFS. I inserted it into the phone, waited for it to prepare the card and this time I got a message telling me that the SD Card was damaged, but I could format it in the phone. I followed the instructions, just as I had before, it went through it's thing, got to the part where it attempted to mount the card, appeared as though it was going to mount, and then nothing, just like with everything else. I have no idea what's going on.
I ran some tools on it and the card appears to be in good condition, so I have no idea what to do. I don't know if it's the phone, or if it is the card. I'm thinking about buying a 128gb card, but I'm afraid if I do, I'm going to find myself in the exact same position that I'm in now and out a lot of money to boot.
I'm loosing my mind with this thing.
Surely you must know someone that has a MicroSD card you can try. Trying another would pretty much eliminate the card as being the issue (and possibly the card tray or similar component on the phone). I have at least 2 "spare" MicroSD cards laying around.
I had a similar problem few weeks ago and I did format my 64gb card with GUIFORMAT on my win 7 PC and since then no more problem. Here is the link: http://www.realmodscene.com/index.php?/topic/323-gui-format-fat32-drive-formatter/
Thank you. I'll give it a shot right now.

You, sir, just won all my Internets. I don't know what it was about that app, but it worked like a champ the first time around. I don't get it either. I had used so many tools to get it to FAT32, but this one did the trick. I formatted the card, inserted it...was totally waiting for it to not work, and I noticed "Unmount SD Card". I read it and thought "hmmm, that's not right", lol. Then it dawned on me that it worked. Copying folders over to it now. Thanks so much, bud. I really owe you one.

Nice. I've heard that the native Windows formatting tool is not the best (although its always worked fine for me), so this might be one of those instances.

Thanks. I had the same problem with a brand new 128GB card with only this phone (HTC One E8 Dual). Until I found this. So far working like a charm. You ARE a star.
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.
