My pen drive for some reason has turned read-only and I can't get it back to it's previous state. I have read the following answers but they didn't work :
When I try running
sudo mount -o remount,rw '/media/USB DISK'', it gives me the following error :
mount: cannot remount /dev/sdb1 read-write, is write-protected
And when I try running
sudo mount -t ntfs-3g -o uid=$(id -u) '/dev/sdb1' /mnt/ it gives me
Mount is denied because the NTFS volume is already exclusively opened. The volume may be already mounted, or another software may use it which could be identified for example by the help of the 'fuser' command.
Any help how to fix this ?
