Could someone explain to me why the following HDD BIOS Geometries don't
represent the values proposed by the drives. What am I missing?
(snippets from boot -v)
BIOS Geometries:
0:030c7f3f 0..780=781 cylinders, 0..127=128 heads, 1..63=63 sectors
1:03fefe3f 0..1022=1023 cylinders, 0..254=255 heads, 1..63=63 sectors
2:03fefe3f 0..1022=1023 cylinders, 0..254=255 heads, 1..63=63 sectors
3:026dfe3f 0..621=622 cylinders, 0..254=255 heads, 1..63=63 sectors
0 accounted for
These don't correlate to the C/H/S values proposed by the drives:
ad0: 8063MB (16514064 sectors), 16383 cyls, 16 heads, 63 S/T, 512 B/S
ad1: 9787MB (20044080 sectors), 19885 cyls, 16 heads, 63 S/T, 512 B/S
ad2: 3079MB (6306048 sectors), 6256 cyls, 16 heads, 63 S/T, 512 B/S
ad3: 4892MB (10018890 sectors), 10602 cyls, 15 heads, 63 S/T, 512 B/S
I'm running 5.0 as of mid-September, but I don't think that's the issue
as Windows tends to exhibit the same behaviour.

Trent.
