Hello everyone I have been using One Plus X updated to 2.2.1 since a week now and purchased 32GB sandisk ultra formated NTFS with it.
Here's something weird on my opx, my SD card keeps sporadically unmounting and mounting again with the annoying message "SD card removed unexpectedly".
The card is where it's supposed to be (checked) and most of the times this happens there phone is completely stationary.
Now, apart from the fears that this will destroy my card, how can i fix this? Any help is appreciated in helping me to solve the issue.
Thank you in advance.

Format it vfat if you need windows compatibility, or just ext4 otherwise and see if the problem persists
Go to twrp to change file system if windows cannot. It should work. I have many sdcards and bigger capacity than yours. So far ok. I use ext4
Also if you're using a custom kernel, check how the NTFS support is in its respective thread.
Nonetheless, vfat and ext2-4 are definitely compatible with Android, so if your SDcard still acts weird then its probably the card itself might be faulty.

I may have encountered a hardware problem with my SGS2. Hopefully I'm wrong, and it can be corrected with software. Anyway, I have a 4GB MicroSD inserted into the phone, but it is not recognised at all.
Under "Settings > Storage" the SD card section says unavailable for both "Total space" and "Available space". The options for mounting and formatting the SD card are greyed out.
At first I thought the MicroSD might not be listed there, and instead was /sdcard/external_sd, but when I copied some files to that directory, they were not on the card when I checked on my old phone. I also copied a file from my PC to the card via my old phone, then searched, to no avail, to find it on the Galaxy S II.
Any thoughts are appreciated.
Format the card via PC card reader . I just shoved 16GB card in and it works .

I have done that. It works in my Xperia X1i. Should I be using FAT32? That is what the card us formatted as, but maybe I should try ext4 or ntfs?

Fat32 should be fine, check the card for errors on your pc? I've just put my 16gb in and it's working fine...
Do you think it could be a fault with the phone? Maybe a damaged card reader? When the card is accessible, where in the file system is it found? /mnt? I know the internal storage is /mnt/sd card.
EDIT:
Never mind, I borrowed another MicroSD, which worked fine. The problem must be with the formatting of the card. Thanks for the help people.

So I figure some people have purchased SDCards other than what HTC provided with our phones...
My question is: What format (based on card size) should we be using?
I had my SDCard (16GB Patriot Class 10) from my Incredible formatted as Ext4 which was causing me a major headache when I wanted to do a Nand Backup. My AmonRa and Clockwork could NOT mount the sdcard. Took me forever to remember that I had formatted it differently. I put in my old 8GB card that was FAT32 and all of a sudden, I could successfully do a Backup.
The catch is that since I am using a 16GB card, when you format (NO Quick Formatting I know) you have multiple options for Allocation Unit sizes. What size should be used?
Reason being is that I formatted the 16GB to FAT32 and default was 32kilobytes as the Allocation size and still I cannot mount the card in AmonRa.
Please help. Thanks.
I have the identical card I believe and I was using Fat32 Default allocation (which ends up being 4k I believe).
Also why were you using ext4? You do know you can partition your card so that you have both right? I can't think of a reason why you would need a 16gb ext4 partition.
What about a 64gb card? I read that someone put one in and had the phone format it and it works fine. No idea how they formatted it, they didn't mention it, so I didn't know there were options until seeing this thread. Got a 64gb card for xmas and would like to pop it in and load it up! Thanks.

I read elsewhere in the Rezound Accessories forum that if you format a 64g card FAT32 the phone should be able to handle it.

At some point in time, probably when the nand was released for HD2 (I had one), we had to use a tool to format our SD card, I think to ext4. Eversince that my SD card was accessible to the HD2 & then the Evo 3D afterwards. Today after I got my Galaxy S III, it is unable to access part of the SD card, although in settings it shows the actual capacity utilized on the SD card.
Is there a way to fix that, considering the SD card stopped being read by the PC after the reformatting to ext4 sometime back ?
Does your SDcard have one or multiple partitions?
What do you mean by 'parts of'. Are there files/folders you cannot access, is something missing, ... ?
The S3 should have no issues in mounting and using EXT4 filesystems since it's internal storage is using the same FS.
Btw there are tools to at least read EXT4 filesystems under Windows (but none I know of to actually use read-write mode, sadly)
duh
I guess he might want to keep the contents =)

I installed ES File Explorer & it only shows the folders that were created by ICS. All my other content is not shown at all. If there is a way I can access the SD on the PC, move all its content then format the SD to FAT32 & move them back. This will solve the problem.
now I have got it. I am an A...hole
I did not notice the phone has internal SD like my pad, as my Evo 3D did not have. So what I was seeing was its internal SD. When I enabled root view in ES explorer, I was able to see 'ext SDCard'. The other thing is, my SD Card got read on my PC. Maybe cause it is Win 7 now. Earlier, Win XP did not read it.
Recently I decided to root and install LiquidSmooth on my Samsung Galaxy S3 9305T for the first time. It's great and I'm wondering why I didn't do it sooner. Although since rooting I've developed an issue with my Sandisk 64GB micro sd card not mounting and appearing as Unallocated in Windows Disk Management. I've tried a few things recommended on here including:
SDFormatter as per advice in this thread which didn't work as my SD card wouldn't detect within the program.
Mini tool partition wizard following this method it seemed to format ok but once I put the sd card in the phone it would bring up an error of 'sd card blank or has unsupported filesystem after partition'. Once I loaded the card back into the computer, the partition would appear as Unallocated under disk management to which I'd try format it again to no luck.
Mounting and formatting the drive in ubuntu following this method. The drive mounted however ubuntu was unable to format it
Mounting and formatting the drive in CWM. The card was unable to be mounted within CWM
Tried formatting the card in a camera at home to no luck
I'm leaning towards the card being dead but before I go out and buy a new one I just wanted to check whether anyone had any advice on if there was anything I may have missed?
Thanks

Sorry should have mentioned that 1GB was allocated to EXT4 and the rest FAT32.
You are in the wrong forum .

I have rooted my z2 and the sd card is constantly mounting then unmounting. This is getting really annoying as when trying to watch movies or listen to music it just stops halfway through because it removes the card. has anyone else had this issue? Also i am unable to download the latest android update all it says is unable to verify.
Well if you unlocked your bootloader to root, then you won't be able to update your device through official ways anymore.
I have no idea about your SD card, try backing up its data on your pc and then reformat the card?
Yeah probably have to wait untill some custom roms come out
reformated the card exfat, however everytime trying to copy to the z2 it will copy for a while then it will disconnect meaning i have to start all over again. I dont think i have came across a tablet that is so bad at handling an sd card truly awfull. I hate to think how bad shooting video will be with the card continously mounting then unmounting. Ans no its not an issue with the card because it works perfectly in my pc and galaxy note 10.1
Anyone ??

What if you reformat as fat32 with 4096 bytes cluster size, instead of exfat ?
Have you tried running an error check on the card ?

not possible to format fat32 in windows no more by default. And the issue is any videos etc on the card will be limited to 4gb file size. The Z2
natively uses exfat so why would it keep disconnecting? when i pop the card into my galaxy note 10.1 it doesnt do it so it is clearly an issue with the tablet, but will give it a try
with fat 32

Then I suppose your tablet has a faulty card reader unit. I'm sure you can get it replaced or repaired without any hassle.
I am on my second, stock romantic same issue on both unless it's in its case
tried fat32 and the same thing happens what an utter load of rubbish cant even handle a 64gig card. btw this i my second z2 same thng happened on the first before and after root. Thought i would try sony as never tried their tablet devices before and was impressed by the specs on paper, what a major mistake the worst tablet ive ever used. Im gonna return it and stick with samsung like i always have and ugrade to the new note 2014 edition. Sony Fail!
Well if it's the second one in a row with this issues, I think there must be something you're doing wrong? Or maybe your SD card specs just aren't supported? What are the full specs of your SD card? And is it one of those extreme high-speed cards for (video) cameras? And aside from reformatting it on a pc, did you ever try reformatting it on the tablet itself? This is an issue I've not read of about this tablet before so it kind of puzzles me that you already had it replaced once and immediately have the same issue again.
its a sandisk ultra micro sd card i have formated both on the pc and the tab. Also i formated it as fat32 but after a while being in the tablet it seems to convert it to exfat again. i have also tried different cluster sizes. I have tested this card in my samsung s3 samsung galaxy note 10.1 pc my laptop and have no problems at all so im at a loss

Only idea I have left is for you to try other micro sd cards and see if they cause the same issue.
I think it might be to to with the number of files the tab can handle if i have nothing on the card it doesnt seem to do it but the more files are added it starts to keep unmounting the card and constant rescanning. i have about 3000 mp3s on the card. Its not like its cheap memory its a sandisk 64gb class 10.
