"found invalid GPT and valid MBR makes me nervous. Any ideas what that's about?


I tried the drive on Windows 7. Windows found it. I tried installing gparted live on the drive through tuxboot on Windows, and that went off without a hitch, but when I rebooted, the Toshiba screen with "press F12 for boot menu" froze before I pressed anything.

I wiped the drive with gparted on linux, then reinstalled gparted live with tuxboot through windows again. Same result -- boot screen freezes immediately if the drive is plugged in.
no its fine. It either gpt or mbr. It says that it is a mbr partition table. So, I'm stump, however, why does it have 2 partitions? Does your harddrive have special hidden programs that is preventing linux tools to read it?
