I got my Dell Streak second hand but the 16Gb card that came with it wasn't working. Not that the seller had mentioned it.
So, I've actually bought 2 16GB micro SD cards and both have had the same problem. The device recognises it upon first installation but when writing further data upon it, e.g. connecting it via USB or taking the micro SD card out and using an SD adapter, the files become corrupted. It doesn't matter what type of file it is, it all gets corruped and it says that the SD is damaged when the phone is trying to mount the SD card again.
This is the 3rd time it has happened so it's no coincidence.
My 4gb that I had in my previous XDA Orbit has been working fine ever since I got my Streak with no problems whatsoever.
Am I missing a driver for 16gb+ SD Cards?
EDIT- Just had a thought. I was transferring all my stuff from my previous card that was in my Streak to the new one, could this have caused any problems? I assumed you could transfer all SD data from one card to another and still have all the apps and data working?
EDIT x2- Had another thought! It seems like when things get put onto the root of the SD card, it causes corruption but when it gets put into a folder, it seems okay. Now this isn't a problem when the device writes things to the SD card- they get put into the appropriate folders, however I have never had this problem with the aforementioned 4gb card and always write pictures and movies onto the root of the SD card to view without any problems.
I pulled my Sandisk 8gb class 6 from my old Samsung Android. I even formatted it after pulling the data I wanted to keep. Powered off and installed it, reboot. Plug in USB and connect it as "disk drive", copy files from PC. Disconnect, phone says "preparing SD card" then "memory card unexpectedly removed" and shows unavailable in the storage section of settings. I've rebooted, removed card, reinstall, reboot and it shows again. Then it will do it again after connecting to the PC. I've even reformatted, and it does it again.
I went through the full process listed above for the fourth time, and have been able to connect and disconnect to the PC copy files two times without an error.
Any ideas? Thanks!

Have you tried formatting the card with your lte?

My wifes card had the same issue. I looked at the card while plugged into my PC and saw some strange files in the root and deleted them. Though you formatted so I am not sure if you would have them. Once I deleted those files (they were hidden system files) her card worked fine. You may need to make sure you can see system files on your computer though. Might be worth a shot.
I had the same issue...actually with 2 different cards. One 16gb and one 2gb. They worked fine when pulled from the GS2 they were in. Once in the Evo lte they stopped working. Put them in adapter to computer and again kept disappearing. I finally said screw it and started using internal storage. I have yet to get a sd card to work.
I plan on taking phone in when I have the time.
im getting the same thing with mine. beginning to think they arent as compatible as people let on about
Picked up the sandisk 32GB class1 UHS card from newegg last week. No errors or other issues.
When I had the original evo, I bought a lexar class10 32GB card. I had strange issues with it. After a few days of use, the phone would drop it (unmounted). Given that my email and other apps make use of this storage space, this was unacceptable. Got a no name 16GB card class2 from a friend and had no further issues.

anyone else have any thoughts to share? I sent my card back to Newegg for a replacement
Hello there,
I just bought a 32GB Class 10 Samsung MicroSD card.
After inserting it, I made sure the phone sees it, and the computer sees it.
So I started transfering files to it...
Every time I try to transfer files to it, the cards sort of unmount, the computer stops seeing the External/Internal storage drivers info (0/0 KB and no files).
I realized I might be needing to format it, so I went to recovery and formatted the external card. Still no good...
If I don't try to transfer files, the internal sd card still works fine.
Am I formatting it wrong? or some other issue? Did I buy a faulty card?
Thanks!
P.S. Some info incase needed:
Using Galaxy S2 obviously, Resurrection Remix ICS 4.04
My PC is running XP SP3
[edit]
Added some pictures to demonstrate what I mean.

Pic 2: The error I get, doesn't mean much except that the pc doesn't recognize the storage device, but just for the heck of it.

If unsure about the quality of your SD card google for h2testw. It is a Windows test software you can use to test your SD card.
Tried formatting it... still no good.
And h2test tries to copy a file repeatedly and after some time it also gets stuck like I do manually...
I was running into the exact same issue as you with an SD card awhile back. Tried many, if not all of the suggestions listed here. Sometimes, the cards just die on you, especially at the most inopportune times...

Open CMD
Type format [letter_of_external_card]: /x
ex.
format E: /x
and wait.
Then format again (through Windows Explorer) with this settings:
FAT32
default allocation size
fast formatting checked
and share the results.

Failure of h2test is normally due to defective hardware.
For SD cards I do not really know but when it comes to USB sticks there are many around that are just cheap crap. You could for instance buy a 8GB stick that will happily accept 8GB of data but only store 4-6GB!. This is where h2test comes into play: it will not only write but also read and therefore check if the data written was really stored in the flash.

Class 10? That card might be just too fast for your hardware.
I'm using Sandisk 32GB Class 4 and never had any problems.
I have tried some Class 6 and Class 8 cards with very various results.
Only class 8 card I found correctly working in my device was Memorex, but it was only 4GB.
So I gave up on fast cards...
its fake or corrupt,did you buy the samsung off a retailer , you always test flash with h2testw before you use it, speed is not the issue,i got a class 10 32gb i had many 16,256,4gb fakes, only 3.7 gb usable droped down to 1kb write then windows couldnt read the storage so you reformat again.
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

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.
Hello,
So my sd card (16gb) appears to have stop working and the phone gives me the message “SD Card is blank or has unsupported filesystem.” This started yesterday after I changed default storage for my camera to sd card. Before that it was working just fine.
I restarted the phone, no luck with that. Turn off phone and remove and cleaned sd card, still no luck. I plugged in my phone to the computer to access the sd card, but did not show up, I guess its cause the card is not mounted? So then I thought I’ll just plug in the sd card to my computer and back up everything and then format to correct, but no that didn’t work… when I plugged it in my computer, my computer did not even recognize my card.
At first I thought maybe my adapter is broken, so I plugged in a spare sd card (1gb) I had lying around and that on worked just fine. So I googled what could be wrong and read that it could be that the adapter does not support HCSD cards. So then I plugged in my sd card into a USB sd card reader (which had a slot for micro sd which I used), but same thing – did not recognize 16gb card, but it did for 1gb card. I checked to see if it’s a driver issue, but it was up to date. Then I doubted the USB card reader didn’t support HCSD like the adapter, so I went out and bought a new USB card reader (one that works with HCSD cards) from bestbuy (Insignia SD/MMC Memory Card Reader). Still did not recognize card with new reader on computer.
I googled to see what my options were, but the solutions that I found all had the computer recognize the card – which mine isn’t doing… but I still tried a few things I read like chkdsk in command prompt, but I got “Cannot open volume for direct access” error.
Even though my computer does not recognize the card, my phone does recognize it but corrupt and offers to format. I also tried it on different phones (Galaxy S2 T989, and Blackberry Bold 9650) to see if it can read it, but same thing it recognizes it but corrupt and unreadable.
I’m still looking around for solutions, but if anyone can help me with this, please do. Please let me know if you need more info.
Info on devices/cards:
T-mobile Samsung Galaxy S5 16gb – 5.1.1 stock rom – no root
16gb micro sd card class 2 – got it with HTC HD2
Micro sd to SD adapter – got it with Samsung Beat T539
Focus camera card reader - got it with camera bundle
Insignia SD/MMC Memory Card Reader
Galaxy S2 T989 – was using latest stock rom – no root as well.
Computer – Lenovo Y50 running windows 8.1 currently. only few months old.
Sounds like the SD is toast. It's not easy to extract corrupted data from a micro sd card
