It should be okay to do as you describe. If the disk is LVM based, see
my comments below. If it's not LVM based, the worst that could happen
is the system will see the partitions and try to mount them under /mnt
or some such. There's no worry that the system will mount the old
partitions over top your existing ones.

A quick fdisk to remove any old partitions, create new, and your off
and running.

If the Volume system you refer to is LVM, then you shouldn't have any
issues with the drive auto-mounting. Been a while since I did this but
I believe you have to tell LVM about the volume group on that drive
before the logical volumes can be mounted.
