I'm going to guess that you've installed this onto SATA drives, and/or
you've enabled RAID in your BIOS. RAID-1 works awesomely on PATA
drives, but one {may|may not} get the above error message when
installing to SATA on some of the 'less-expensive' mobo's. Things get
tricky when one writes grub to the MBR, and need to swap out the
primary drive.
You can also put swap into RAID as well. Consider two PATAs in parallel:
md0-swap-swap-{hda1|hdb1}
md1-ext3-/boot-{hda2|hdb2}
md2-ext3-/{hda3|hdb3}
What does:
cat /proc/mdstat
say?
BTW, mdadm automaticly rebuilds your RAID devices if you startup using
'Rescue' on the 10.2 DVD :-) Way cool!
