I have a Mentor Media Dell USB drive that holds Windows 8 recovery media. Obviously, this is completely useless. I'd much rather have this drive store something actually useful, like a Ubuntu install.
However, I can't format this drive. It always comes up as "read-only filesystem" even after running
sudo hdparm -r0 /dev/sda on it.
I found this guide online, but I can't use the linked tool because I'm not on Windows. Is there any way I can format this drive from Linux only?
