I have this micro sd card on my phone, I have installed TWRP on my phone and use it with this sd card. I'm not so sure what have Cyanogenmod done on the sd card. But I can't make any changes on it.
I'm in LInux mint, I mounted, delete files and I dont get any error or anything similar, it acts just like if im deleting the files, but as soon as i plug it on the computer again there are the files still. Same with formating, I've tried with gparted, format, delete or anything, pretty much what i get is the action it self like there was not problem but after finish the formating for example it goes back to the old same state, the same partition, and the files are there. On the terminal inside of TWRP when I tried to delete the files inside of the card with "rm" it says they are "read-only". It's an micro sd, there is no swtich of read&write. I have tried also with windows with this tool is everywehere diskpart because i thought there was some kind of encrtyption. I really want to save this card, I dont want to but another one.
Does someone has any idea of what to try or may be what exactly is it?
