(Sorry, I'm still a tad confused between the disks)
If it's a local disk, can you not just mount it? If a simple 'mount /dev/hda /mnt/mntpoint' wont work., 'man mount' for other options.
If the disk is on another computer in your network, try and smb mount it.
'smbmount //zion/kristijan /mnt/samba -o username=root,password=<password>,fmask=777,dmask=777'
That's what I use to mount a disk that is on my other PC. I'm not sure if it's really safe to mount it as root, but it seems to work fine with me.
