Thanks for the quick reply. However, this is external USB disk (250Gb 
and I just added it to the system as a backup disk. FC5 was running and 
before I did anything the disk was formatted as a FAT32 disk I then did 
a pvcreate. When I checked the disk was empty (as was expected). The 
vgcreate did the strange thing, which is a problem as I cant remove this 
VolGroup00 as there exists one on the other (2) disks and when I asses 
VolGroup00 it rightly goes to the original VolGroup00, which I cannot 
I think the only solution is fdisk and see if it will free the whole 
disk. But any other ideas?
