That worked perfectly. Thanks very much.
When I first tried it I thought I may have gotten the command wrong so I did mkfs.xfs -m crc=1,finobt=1 -f /dev/sdg as that is at the end of the description on that drive.
It did it thing ok and didnt give me any errors, obviously it didnt work, however what damage if any would I have done by using sdg instead of the correct command?
Regards
