SD Card unmounting unexpectedly - Sony Xperia T, TL, TX, V

Hey guys,
As of Sunday evening I'm having a recurrent problem where my phone is nearly constantly unmounting and remounting the SD Card, or not recognizing it at all, or saying that its corrupt, this seems to be causing the top of the phone around the sim / sd card cover to get warmer than normal and a significant hit on the battery life, for example today it's been off of charge for about 4 hours and now i have less than 30% battery left.
Obviously this is not normal and there is a fault somewhere so i figured I'd ask here to see if anyone had came across similar issues and see if there was any obvious fixes before doing anything drastic.
The phone is running TiMiN8R's rooted and deodexed JB rom. Locked bootloader, extended standby time is disabled. the SD card is a sandisk 32gb class 4 card.
not sure if that info helps but i figured i better specify it in case anyone asks.

Try to reformat or -partition your card. I think I have seen more problems with Sandisk cards, sometimes only solved by buying an other card. I have no problems with my own Sandisk 32GB though.

I'm about 90% positive that it was a fake card now, i put an old 8gb card i had in it and its been running fine since, I put the other card into my computer to check it and it's now claiming it's a 32mb not a 32gb card.

Was having this problem with my old san disk 32gb class 4 card. Now im on a new san disk class 10 32gb card and have not had this problem for almost 1 month

I think you may have a faulty card. I had a SanDisk Ultra C10 32GB and suddenly it behaved the same way. Even worse, I can't get the card to recognize even if I took it to a PC. If I used a 16GB C4 card, then everything was okay.
I sent in my 32GB card for RMA.

I'd also bet you've got a faulty card. I bought one of the Maplins 32GB cards and had a similar problem with overheating and unmounting. Replaced it and not had any trouble since.

Oh crap, think I have the same problem as it had stated happening to me out of the blue sandisk 32g card bought from a reputable seller on thief-bay. I'll reformat first and see if it persists.

External memory card issue?

Have a 32 gig sd for about 2 weeks now and had no problems until yesterday. Now media scanner says it is a blank memory card and won't read it. I tried formatting but no luck. Anyone else have this issue before? Is there a fix? Thanks ahead of time for any info!
Where did you get the card? brand? I've read a lot about people getting fake cards from China that are awful quality. Not sure if you can do much but re format it with the computer

Best SD card?

What is the best sd card for x8?

It really doesn't matter what brand you buy. I mean except if you buy Kingston, because Kingston memory cards/ mermories has got life-guarantee, what means if it failing, then if you bring back the place where you bought it, they'll give you another.
So, the only thing that you need to know about memory cards is that every MC have got Class. This stands for the speed of the card. Higher class=more money.
A Class 6 memory card will be ok, above this class the cards are horribly expensive, below this class they are slow.
I recommend you to buy a 8GB Class 6 card. 8Gigs are enough for a really lot of thing. I'm using a Kingmax 8gig Class6 card, and I just can't put so many things on it to be fully loaded
The u very much for the detailed explanation

Try doing a Full format, and see if it still gives the same errors,
failing that check with a SD card reader on a PC, if it gives the same errors,
those cards should be with a Lifetime warranty if I am not mistaken?

dude, just a question. is your SD card still usable after the message popped up? cause i experienced once the same issue and i ended up buying a new SD card because my SD card becomes corrupted. by the way, i am using kingston 32gb class 4. today i have my new SD card and i'm afraid that i will face the same issue again after reading your complaint.
My original is only useable when connected to PC via card reader even after a format it is still not reconized by the phone.
My new Card is now behaving and since writing this topic it has resumed and working OK.
Not sure what caused the prob to start with but now I stuck with a card that I feel will fail at any time so I can't transfer data/apps etc in case it fails and have to go through the hassle of back up to PC then format then re transfer to card.

so in short, your SD card is not corrupted since it can be read by your computer?
Yes but my Sp and my arc and my old x10 will not read the old SD card.
Edit in the last half hour the new SD card had again stopped being recognised and getting SD card removed unexpectedly error......aaagggghhhhh

I also experienced the same thing, since I use a sandisk class 10 3 months ago I was having this problem,
I've done a variety of ways to fix it but just the same, I have not tried it with the sd card to another,
so I do not know the cause masalh this from sd card or from my hp
sorry for my bed english
When ever I put a faulty in an other device it is not recognised.
PC will read it OK backed up then have formatted so many times.
it works OK for maybe 3-5 days then get errors.
The new card I got in august 13 plays up every so often.
An old sandisk class 4 16gig (from x10) seems to be OK, if this goes then I know it is Sp as this card has been working fine in x10
Sent from my C5303 using xda premium
My SP has the same problem, Sandisk Ultra, 64GB. The SD card is just fine.
I'm really wondering if it is a hardware or a software problem. The SDcard is kind of loose in its place, maybe its the build of the phone or something. Guess I will have to send it back to repairs again then.

64gb microSDXC class 10 intermittent unmounting

This just started happening on my rooted stock gs4a, anyone have any ideas besides sticking a piece of business card under the microSDXC card?
If I reboot it resolves it temporarily...

It has nothing to do with it not being seated properly. Something about the 64g card that the phone doesn't like. Has to do with the software. Try and 32gb card and you'll probably never have that problem again.
