On another machine it was running in a hardware RAID with a second 40GB disk, giving (on the old machine) 80GB. Now I'm was trying to use this hd on a new computer without RAID, just as a plain ATA hd. But the FC5 installer would always see it in /dev/mapper/ directory as a 80GB hd. And I was wondering what do I have to do so it wont be recognized as a RAID member (I guest that's why it's in /dev/mapper) but as a regular ATA hd as (/dev/hda). I've managed to achieve that by connecting the hd to a Win2K workstation and using the disk admin utils made the whole disk a simple NTFS volume and formated it. After that, putting again in to the destination machine FC5 installer found it as /dev/hda with one NTFS partition as /dev/hda1 just as expected. I has hoping I can do that without taking the disk to a Win2k machine, just using FC5 installer.
