I have read-only usb drive and could not fix it. I have read some articles about it and tried to fix but I couldn't.
I unmounted drive and used dosfsck
to check and repair MS-DOS filesystems, because it is FAT
filesystem and run:
dosfsck -a /dev/sdb1
it gave the output:
fsck.fat 4.1 (2017-01-24) open: Read-only file system
So what can I do with it? Can I repair or it's time to throw it in a trash?
