Apres 15 secondes de recherches sur deja-news, je constate que t'as tort
de t'inquieter, c'est conservé:
search "linux fdisk ide quantum"
me renvoie plein de touches, dont:
(notons au passage l'existence d'un 'large-disk' howto cité dans un de
ces posts....)

fdisk as usual
Do you want one big partition or multiple partitions on that disk?
: I have a Maxtor 91000D8 (10Gb) Hard disk.
hda: QUANTUM FIREBALL EL10.2A, 9787MB w/418kB Cache, CHS=19885/16/63, DMA

^^^^?
: There are 2 FAT32 partitions :

Could you give a screendump? Dmesg info?
# fdisk
Using /dev/hda as default device!
The number of cylinders for this disk is set to 19885.
This is larger than 1024, and may cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software form other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Usually it is very unwise to go into expert mode, or to give
boot parameters "hd=cyl,head,sector".
If the RedHat boot scripts fail, go to some other virtual console
where you have a shell prompt and do things by hand.
There are bugs in Disk Druid (also in fdisk, but less harmful)
so probably what you want to do is:
1. Look at the kernel boot messages. This is by far the most
important step.
2. If you have garbage in the partition table, zero it out using
dd if=/dev/zero of=/dev/hda bs=512 count=1
(if your disk is /dev/hda).
3. Use fdisk to partition. Note that the large-disk howto says
-----------------------------------------------------------------------
7. The Linux IDE 8 GB limit
The Linux IDE driver gets the geometry and capacity of a disk (and
lots of other stuff) by using an ATA IDENTIFY request. Until recently
the driver would not believe the returned value of lba_capacity if it
was more than 10% larger than the capacity computed by C*H*S. However,
recent Quantum Bigfoot 12 GB disks return C=16383, H=16, S=63, for a
total of 16514064 sectors (7.8 GB) but give lba_capacity of 23547888
sectors (11.2 GB, that is, C=23361).
Recent Linux kernels (2.0.34pre14, 2.1.90) know about this and do the
right thing. If you have an older Linux kernel and do not want to
upgrade, and this kernel only sees 8 GB of a much larger disk, then
try changing the routine lba_capacity_is_ok in
/usr/src/linux/drivers/block/ide.c into something like
static int lba_capacity_is_ok (struct hd_driveid *id) {
id->cyls = id->lba_capacity / (id->heads * id->sectors);
return 1;
}
-----------------------------------------------------------------------
in other words, you need 2.0.34 or more recent for a > 8 GB IDE disk.
4. When the partition table looks OK, restart the install.
The RedHat install gets confused if you change partition tables
under it.
Might things fail, please give the kernel boot messages for the disk,
and what error messages you may have got.
Probably an easy repair is possible.
