It's a pity the system was running on a rescue CD so when I had to reboot
(the client really needed to have it up soon) I lost the messages. I can
tell that I bypassed the problem swapping the position of the two HD (hda
and hdc). At that point both where seen in LBA mode and the partition could
be added... I that any usefull to help understand? Is there anything I
could/should have been done to avoid this behaviour?

Why hdc is so often seen not in LBA mode (BIOS set up correctly) until you
force it w/ fdisk while hda is always right?

Thanks for your help
