or

Code: Select all

Re: Remove write protection on a usb drive

You can check with hdparm : sudo hdparm /dev/sdc /dev/sdc: multcount = 0 (off) readonly = 1 (on) readahead = 256 (on) geometry = 15904/64/32, sectors = 32571392, start = 0 Change it with: sudo hdparm -r0 /dev/sdc1 If it doesn't work, it might be a problem with the USB drive.
