I actually tried with 3 different sets of hardware - the computer that the drive was initially in, another computer that was untested with FOG (the same issue occurred) and then finally with the computer that was known-working with FOG (initially I didn’t want to open up the working computer to try it in there, but did it anyway out of desperation).

All three computers were working fine before I began the exercise (i.e. able to boot into their respective operating systems), but only one (the third one) was tested (and was working) with FOG.

The hardware is very diverse (see below), but all three are 64bit machines.

Computer 1:
(has since stopped working for a different reason - coincidental psu failure)

Computer 2:

Computer 3: (known working with FOG)
[SIZE=12px][FONT=Helvetica Neue][COLOR=#000000] Zotac NM10-F-E Intel Atom D525 CPU (1.8GHz) Motherboard (including built-in processor and graphics)[/COLOR][/FONT][/SIZE]

In any of these machines, inserting the proxmox hard drive caused FOG to fail with the error described above. The drive was originally in computer 1.

Any thoughts as to what might be causing this?

Thanks!
