OK,
I had to acquire an ultra ATA 133 pci card as the disk was over 200G. I left the
original disk in it 's orginal configuration. The system comes up and the BIOS
detects the hard drive as I can see it...
Now I have to figure out what device it is recognized as? I presumed /dev/hdb
but when I issue an fdisk I get the following error:
fdisk /dev/hdb
Unable to open /dev/hdb
So I tried the pvcreate command:
pvcreate /dev/hdb
pvcreate -- can 't open physical volume "/dev/hdb " to get its size
If I can locate the disk I can do the rest. Can anyone help me out here?
