Huge files, huge numbers of files, everything's great. Based on the specs I found in Wikipedia, I wrote a program to back up the front GPT area and compare it to the rear EPT area, so it's like backing up the first 512 bytes of a MBR formatted disk. > I'd be more inclined to try EFI, EFI is the booting method used to boot from a GPT formatted disk. You can't use EFI on a disk that isn't GPT. I could write a 2000 word essay on the many reasons EFI boot sucks. This is the logic... If you're booting to a GPT partitioned disk, you must use EFI boot (or maybe that phony compatibility MBR). If you're booting EFI, your boot disk must be GPT formatted. If you're booting MBR to an MBR formatted disk, any other disks on the system can be GPT formatted or MBR formatted, your choice.
