ERROR: isw: wrong number of devices in RAID set

When running
sudo update-grub
this error message came up
ERROR: isw: wrong number of devices in RAID set "isw_djcbaiedeg_RAID_Volume1" [1/2] on /dev/sdb
There is no RAID setup on my computer so this is probably caused by the disk (/dev/sdb) that might have been used in a RAID setup before. The RAID medata still remains on the disk.

Fix this problem by using the dmraid command to remove this metadata:-
sudo dmraid -rE
