How can I properly remount /dev/sdb1? Because when I remount it:

sudo mount -o remount,rw /dev/sdb1
mount: cannot remount /dev/sdb1 read-write, is write-protected

...displaying that it is write protected. Before this happened, it is read and writable, but when I connected it to my laptop, it just got this, read-only file system. I retry to mount and change its file system/permissions. But it doesn't change.. Need help please...

  • I got the exact same error message with a disk drive in a desktop I was moving daily. My issue ended up being a loose sata cable. Fixing the cable and rebooting fixed that exception for me. – nburn42 Jul 30 '18 at 18:56

Execute following commands in terminal.

id user_name

replace user_name with your user name to get your uid then execute this command

sudo mount -o rw,uid=your_uid_here /dev/sdb1 /mnt

replace your_uid with uid of your user found above.

  • I try it and then it displays: 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. – florentine francisco Mar 17 '15 at 2:23
  • okay then unmount it first. sudo umount /dev/sdb1 – Faizan Akram Dar Mar 17 '15 at 6:49

    This doesn't seem to work. I've un-mounted and then re-mounted with rw and my uid but still it's a read-only system... – ComputerScientist Mar 22 '18 at 18:26
  • i used this command on sda1. After unknown error that trigger errors=remount-ro. and after sudo mount -o rw,uid=1000 /dev/sda1 /mnt - i got mount: /mnt: /dev/sda1 already mounted on /.. so this didnot work for me – Vladimir Ch Apr 4 at 13:54
