Thanks Denis,

I'll see about trying this, but one thing that I have noticed though is
when I do and "fdisk -l" to list my disk attached to the system, I can't
see the newly assigned disk in order to format them.

Hello Stephen.

One thought <insert usual disclaimers here> is to add the new disk
specification to /etc/fstab, create a suitable mount point, then use the

"mount" command.

I see this as directly analogous to having (say) a floppy drive listed
in
fstab, and having a mount point assigned for it, then actually
"attaching
it" on demand using the mount command.

It is probably a Good Idea (tm) to try this on a non-production machine
first <big smile>

Reading between the lines of your post though, perhaps you have tried
this
already. I must admit that normally disk specs in fstab and mount
points
are known quantities when a machine boots, so maybe the idea above is
invalid?

HTH,
Denis
