UEFI can address 4TB. If you are using BIOS, that could be a problem. With 512-byte sectors, 2TB is about the maximum representable offset. BTW all the documentation I've seen about BIOS boot sequences assume 512-byte logical sectors. How is BIOS supposed to handle 1024-byte or larger logical sectors? -- Michael hennebry at web.cs.ndsu.NoDak.edu "SCSI is NOT magic.
