I just created a bootable USB Linux Mint image. Everything worked fine but now i cannot format my USB pend drive. I tried to use
dd if=/dev/zero of=/dev/sdb and
udo mkfs -t vfat /dev/sdb but these gives me an error:
unable to open /dev/sdb: Read-only file system.
I also tried to use the command
sudo hdparm -r0 /dev/sdb like it is suggested here, and this gave me the following output:
setting readonly to 0 (off)
readonly = 0 (off)
But didn't solve the problem.
Do you have any suggestion to help me?
