I have this 64 gb micro sd card, quite old already, used to use it a lot on an old phone and after changing it really forgot about it. A few months ago I remembered about it and tried to reuse it but when plugging it in, even after formatting it, it always has a file named "abcd.iso" that weighs about 32 MB. Also, it says its total space is about 2 GB instead of the 64 it's supposed to have. I used to mess a lot with the files I had there, backing them up multiple times because every time that old phone ran out of battery or restarted, it never recognized the SD card and would always say it was damaged, forcing me to format it, and all that happened, like I said, multiple times. Is this even fixable?
