I have a couple of 40 GB drives in a machine whose BIOS only supports
hard disk drives up to 32 GiB. The motherboard (BIOStar M6TLC)
manufacturer has confirmed that it is not possible to work around this
limitation via a BIOS upgrade. Since installing Debian unstable in a
dual boot arrangement with W98SE I have used the space between 32 GiB
and 40 GB on each drive for a mirrored array.
However, cfdisk, fdisk and Partition Magic report problems with the
first disk:
Look carefully what do they tell you. You may also look at your kernel
report (dmesg|grep hda) of what it says.
The problem is that geometry the partition table was built with can differ
from the geometry hard disk reports.
fdisk usually works with the geometry the partition was build with, unless
it was rebuild, in such case it's afaik taken from kernel (what hdd
reports). in fdisk's expert mode, you may change the geometry manually.
However fdisk is able to display/entry in cylinders or sectors. In the
latter case, you may enter whatever size partitions you like, but fdisk will
in such case re-compute geometry itself :(
OK, testdisk reports:
