You need to manually configure the drive geometry to use the full space on your drive.

OK, but how do I go about figuring this out?

Thanks

Page 21 of the first link you posted gives maximum values. ;)

I think you are going to have to limit track surfaces to 65535, the maximum is 90,774 for the 300GB version.

But it's all there mate. You just got to figure out what the maximum values are that 3.9 will like..

... and look on the bright side, that's LOADS more than a 3.1 machine could access.

I still think it will crap out about 128GB, but you are the explorer in this case - you might just find out something new.

OK, I changed the Max to 90,774 from the specs and the most I was getting was 64Gigs. The geometry was pre-calculated for me based on the MAX size. The system dumped out 10 drives but I was only able format 4 @ 16gigs..the rest kept giving my DOS errors.

So this is what I did:


90,774 =64.9 Gigs
X = 300 gigs
===========
X= 419,602

I entered this new number and was now able to get 3 drives @ 75Gigs (225).
1 for APPs, 1 for OS, 1 for Audio & Projects
I suspect the limitation is on OS addressing side.
(Note the actual size of this HD is 279gig)

still, 225 Gigs  is not bad right?
