Formatting second internal hard drive

[john levin]

Hi,

I have a desktop with two large (200 gb) internal scsi hard drives. When 
I installed Ubuntu Dapper, there didn't seem to be a way of formatting 
both the drives, so that the home directory would span both of them. 
Consequently, I used one drive (with LVM) for the filesystem, and left 
the other free.
Now how can I use the second drive? The Disks Manager doesn't seem to 
offer a way to mount it, nor does gParted, and it's not done automatically.

TIA

John
