Hi,

Ian and Volker already explained it ;). However, I'm not sure that you
simply can migrate from MBR to GPT.

"Disklabel type: dos" is for MBR.

Regarding to the "1.5 Gb/s", the drive obviously is connected by
SATA less than version 3, so I wonder if the motherboard's BIOS could
cause issues when using GPT. All modern "UEFI" mobos are providing SATA
version 3, while old legacy BIOS mobos tend to provide SATA 2 only. It's
not the version of SATA that might be a problem, but the legacy BIOS
might be the showstopper. Maybe you own a UEFI mobo. It's possible that
it has got SATA 2 and 3 connectors.

Just hearsay about GPT issues when using legacy BIOS. I don't have got
experiences, since I'm using a modern UEFI equipped mobo, but anyway
stay with MBR ;).

Ralf
