gparted?
Gparted looks pretty. As far as I can see, gparted agrees
with what I think things should look like. Gparted and
fdisk agree about the number of sectors. (More than you
get by multiplying CxHxS.)
Interesting. I guess it would be best to use 'hdparm -i /dev/sda|grep
LBAsects" to find out the number of sectors.

[root@live ~]# hdparm -i /dev/sda | grep LBA
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=1953523055

Same number of sectors as gparted and fdisk report. Number of heads
and sectors per cylinder are just, "it's a big disk". _Posssibly_
number of cylinders gives a clue about how big. H can be 63 or 255,
depending on mood, and CxHxS should be a little less than max LBA.
The situation just got worse. The latest work arround is to lie
about how big a sector is. That is called "advanced" formatting.
Coming into this a little late, but I read somewhere that cfdisk was to
avoid, because of unsolved bugs which could result in disk corruption.
That was a while back, but apparently it still applies.
BTW, with all those partitions, I would convert your disk to GPT tables
instead of MBR, using gdisk.
(gdisk is in core.)
It will make your disk more stable.
It uses a 128 partition table,with a backup table at the end of the drive.
No such thing as "extended" partitions.
It takes less space than the ms-compatible MBR partition tables.
The only trick is that you need to leave space for the backup table (34
512-byte sectors).
If you change your mind, you can convert back painlessly.
I've used GPT for over 2 years, including converting back and forth a
few times at first.
To convert, you'll have to boot to a live disk, preferably with gdisk.
I use systemRescueCD for that. http://www.sysresccd.org/
The latest stable version is 379 Mib, usable from CD or USB key.
I don't know if a Mageia live cd, or Mageia DVD in rescue mode might work.
Just in case you might be interested
