how do you unlock a hard drive in the pc registry, I used the disk to redo my laptop and when it was done I only had the 50G hard drive, the 350G drive is missing, I called toshiba and the said i have to enable it in the registry and for $50 they will tell me how. I have windows vista, can some please help me? with the windows and all the toshiba stuff to run the pc i only have 10Gs left.

It has nothing to do with the registry, you simply "redid your laptop" incorrectly. Have a look in Disk Management, you'll probably find there's a lot of unallocated space.
