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.

I've looked at the other threads on this but, none seem to match my problem.
I've a 16 GB MicroSD card in my S2. S2 is not-rooted running stock ROM.
This card used to mount ok. It no longer will.
In Settings->Storage, space reported is unavailable (because it's not mounted).
I can run Format SD Card option which returns quickly.
Running Mount SD Card, it's says Mount in Progress but it never completes.
If I put the card into an SD card reader, it looks fine. FAT32 formatted card, with approx 16GB available.
Any ideas?

I had similar problems with two other sd cards.
First running without any problem, and then suddenly the message appeared that the sd card is empty or not connected.
In both cases, the sd card was broken.
But in my cases, the sd card could not be used in a USB adapter by PC either.
As the sd cards were nearly new, I could make a warranty replacement and now I have got a card which works fine for about two months.
You can check this, by switching the sd card into another phone.
And use another sd card in your phone.
If the other card will work in your phone and your sd card will have issues in the other phone too, replace the broken sd card.
Good luck !
P.S.: You should format the sd card with your phone and not by your PC.

Thanks for the response. I should have said that another 4GB card worked in the phone ok. This did lead me to think it was a card problem. However, he fact it works via a PC indicates otherwise.
Will try it in another phone.
Just throw it away?
Has anyone seen this before i.e. not working in phone but ok in SD reader?
If so, did you manage to resurrect it? Or is it time to throw it out?

Try this. Settings>Application>Development
Check usb debugging.
Connect phone to pc. In notification bar click "usb connected" message, and click on "connect usb storage" button. You won't see the sd card mounted in pc!
Now disconnect phone, reboot. It might mount
See if there's any luck.
Since you're not rooted, solutions are quite limited in numbers

Tried disconnecting and rebooting in 2 senses of the word
1. Hitting the disconnect usb storage button on screen
2. unplugging the usb cable.
Unfortunately, neither worked.
i'm having this problem now both on internal and external sdcard... it wont even mount on recovery... i'll try see if i can this done.. Windows damages everything.. i made a cleanup of the sdcard and a format..
Hey. I bought a new _cheap_ SDHC card online, 32gb... When I put it in my phone, the phone gets pretty slow while there's a notification saying "Preparing SD card" "Checking for errors."
Now it stays there for a long while and the phone gets very hot... Is the card defect or is there something that can be done?
Have a look for H2testw
Well the problem is that i can't mount the card since i don't have a card reader...
Please forgive me for not being psychic, you didn't say that originally.
No need to be hostile man.
Anyways, i let my phone run for a few hours, still nothing...
Does anyone have any idea? The phone IS rooted, so that might have something to do with it, gonna try to unroot it today to see if that makes any difference.
this happened to once, I bought a 32 GB from amazon and it was cheap. It was a disaster, all my data I stored in it was erased spontaneously. I returned it and had a refund. My guess, the sd_card is inferior
y don u get a cardreader an check for eerors or format an c....or u can set usb debugging and do tht if dont hav card reader...some use 64gb card wiv no prblm..
You don't need a card reader to check for errors if you don't have one. Just plug your phone with the card in it into a computer and search for your card in windows explorer and check for errors there. You can also format it from there also.
I managed to check it on a card reader today, windows does recognize something is going but doesn't allow me to format it or do anything except change the drive letter basically... When i check it through computer -> manage -> disk management it shows it as a MBR? Why is that and any way to go around it?
Oh and i can't access the card while it's in my phone at all, it just keeps looking for errors and doesn't mount it?
preparing SD Card and checking for errors
I am also having the same problem, My sd card always shows the message Preparing sd card and checking for errors in galaxy fit and I have formatted it in my pc and then tried all the other methods like deleting the msdos file from system/bin etc but still the problem persists. would there be any problem with my phone of sd card slot kindly reply
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

Added some pictures to demonstrate what I mean.

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...
Sent from my DROID RAZR using Tapatalk 2
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.
Hi
My Xperia Z2 tablet stopped recognizing the SD card. It was perfect before turning it off. When I check "storage" under settings it says mount SD card. Nothing happens when I try to mount it. Is this an SD card issue or a tablet issue?
Thanks

My card is Samsung 64 GB Class 10, bought from ebay. I had a movie on the card which I was watching on the tablet last night. This morning however, the tablet did nor recognise the card. All it says under "storage" is mount card, and i tried mounting the card but nothing happens. The card was not formatted on a computer, but erased by the tablet before being used.
The reason I mentioned ebay is because, according to google, many cards on ebay are fake. I'm only hoping it's the card not the tablet.
Thanx
What File Manager are you using? This happened 2 times on my Xperia Z Ultra and 2 HC 10 32 GB cards were destroyed...but it happened only by using Total Commander, since that time I do not work with him anymore and everything is fine...

I did not install a file manager. The tablet came with File commander, and that's the one I use.
There are a lot of fake/faulty sd cards on eBay, try it in a different device.

My card is exactly the same (I think) Samsung miniSDXC 64GB. Bought from a normal retailer. Similar problem to yours (I think)
I have not been able to find a solution.
The SD worked fine for a couple months. I notice there is no click upont pressing the card in (as the Sony manual describes) but it seems to sit a fair way in. Sometimes when viewed in Settings the card is visible but never when the phone is plugged into a USB port of the computer. Mostly it shows instantaneously when you push it in and then dissappears as quickly and the request to mount a card shows.
On one of the few times it stayed visible (not with the USB cable in) it showed about 12GB used. It seems to have been coming on and off intermitently during use. Accordingly, some photographs end up going to it and then not being accessible and some, or most, just end up in the main phone memory. This is assumed as a number of photographs taken are not showing. I have sent them from the phone main memory via dropbox as the computer can access none on the phone at all...perhaps because I have pathed them to the SD.
Will get and try another SD card but one possibilty is that this may be a problem with the SD card housing in the telephone.
.
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:

- Unlocked Bootloader

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/

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.
