Ahhh...so that's the LVM I've been hearing about...

Thanks - those commands confirm both my assumptions and yours.

Since I've already added an additional IDE drive (/dev/hdc) once without
even realizing that LVM was there, I assume that I don't need to use
it to add this new SATA drive?  I can just follow my usual steps of
fdisk, parted, edit /etc/fstab, etc?

(this drive is just going to be a place to archive large files - mapped
into the filesystem at /backup or something)

Thanks,
Chris
