Code:

Disk /dev/sda: 107.6 GB, 107639996416 bytes
255 heads, 63 sectors/track, 13086 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        7605    61079104   83  Linux
Partition 1 does not end on cylinder boundary.

Is it possible that the whole drive was LVM'd (as a PV)? Partition tables can be a bit "old school" today.

Try pvs or pvscan see if that helps (just a guess, an idea).
