I did mange to get it working with fdisk. You have to change the CHS
values and, in the same session, create a partition spanning the
entire disk.

Sorry - I should have provided more details! How silly of me. I'm
using kernel 2.2.14 + raid-2.2.14-B1 + ide.2.2.14.20000111.patch.
It's a non-SMP machine with Promise ATA/66 adapters to hang the big
disks off.

The fdisk version is the one that comes with Redhat 6.1: fdisk-2.9w.
It has the value 65535 hard-coded into it so will need changing to
support big drives at some stage.
The same behaviour occurs with kernel 2.3.39 + ide 2.3.39.20000110.patch
i.e fdisk sees 7144 cylinders instead of 72680.
I can see two solutions:
1) Fix fdisk to handle > 65535 cylinders and modify the
implementation of HDIO_GETGEO to return 32-bit cylinder numbers.
2) Get linux to translate CHS values so that they are <= 65535.
