It can't see past 8.4 gig or it won't report past 8.4 gig? I think what was being referred to was that the BIOS can see just past 8.4 gig, deducts the hibernation partition and tells the OS there is in fact 8.4 gig (where the difference between 8.4 gig and what the BIOS can REALLY see it keeps for itself for hibernation). It therefore DOES use all the disk, it just has dibs on the last bit and doesn't tell the OS about it. - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
