It appears that this machine is running SATA, If that changes things, 
let me know. When I try to do a:

# hdparm -i /dev/sda

I get

/dev/sda:
 HDIO_GET_IDENTITY failed: Inappropriate ioctl for device


# fdisk -l

gives me:

Disk /dev/sda: 164.6 GB, 164696555520 bytes
255 heads, 63 sectors/track, 20023 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14       20023   160730325   8e  Linux LVM

But I would really like to have the model, the size it thinks it is and 
other various details. Is it possible to do this with SATA drives?

New Plan:

1) Install new hard disk along side the current hard disk
2) dd if=/dev/sda of=/dev/sdb conv=noerror,sync
3) remove bad hard disk
4) re-cable the new hard disk using old hard disk connection
5) pray twice as hard
6) reboot
