wipefs device or resource busy
I am trying to format a drive using the Ubuntu Disks utility. When I select and try to format the drive I get
Error wiping device. Command-line wipefs -a "/dev/sdb" exited with non-zero exit status 1: wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy (udisks-error-quary,0)
Nothing I know of us using it and I am doing this from a Live CD boot. What to do?
Solution 1:
Use the -f (force) option:
wipefs -af /dev/sdb
Solution 2:
Unmount the disk and all the partitions on it:
sudo umount /dev/sdb*
Then retry the wipe.
