[PLUG] Hard drive: size discrepancy

[Rich Shepard]

   I have a Seagate Barracuda XT with marked capacity of 3000GB. It was in a
sealed external enclosure which I disassembled.

   The drive had a MBR/DOS partition table type. I used gparted to change
that to GPT. However, gparted sees only 746.52GB on the drive. It still has
a DOS/MBR boot sector.

   What can I do to find the missing space on the drive and remove the MBR
since it's no longer needed.

TIA,

Rich
