The reason it shows as being in use is because you have an active logical group on it. You have to deactivate VolGroup01/LogVol02 before you can do anything else with /dev/sdb1. You can use Logical Volume Management to do this as well.

Ok that problem is fixed. I used the gnome live cd but run xfce, so it's system-config-lvm for me.
It's rewritten the file system so I should be able to start again from scratch. This may take some time since I'm learning by doing ...
Thanks for the help.
