[Q] 64gb microSD randomly deletes files.

[Abysswalker]

Hi xda guys/gals,
Recently I got a Samsung 64gb microSD to use with my Sensation, formatted it and everything, copied over the data from my previous card (32gb) and it seemed to work until I started putting music on it.

Whenever I try to add anything to the card, it'll look as though it's there, but when I remove the cable, the files are just gone, as if they'd never existed. The same thing started happening with other files, like pictures and such. The ones that my phone will easily access on my 32gb card seem to not be there on the 64gb card.

I've reformatted multiple times, and still the problem persists.
One thing I've tried is to put music in already existing folders. That made it "work", but the songs weren't tagged, were unplayable and apparently had 0kb.

I read a thread somewhere on here about someone with a similar problem (different phone, I believe, though I can't quite remember) but nothing seemed to have come out of it.

I can live with a 32gb card but I got a 64gb specifically for music (you audiophiles out there will understand). Is there any way for this to be remedied, or am I just kind of screwed?
Thanks.

What did you used to format it, PC or phone? Try doing it with phone if you haven't. Also, try to remove it from phone and to transfer files using some card reader.

I formatted using 4ext recovery, and I have tested it with a usb card reader; still doesn't work.

When you boot 4ext have you got an error message about "no mounted sdcard"???
