Yes, you're right - there is the option to undo whatever changes are made but it could not detect the partition I had at *all*. > > This is a partition table from a woody install.

If it > doesn't how you can partition the disk on Linux? The woody installer used fdisk (which may have caused the problem, actually.) Parted complains when I try to get it to see the disk. I should also mention that when I installed woody, I wiped out the existing partitions, specifically /dev/sda3 (the whole disk partition) which is apparently some kind of required feature of Sun disklabels. The Solaris install partition table geometry is 2733/19/80, whereas the Linux hdparm -g is 1017/67/62. Parted complains about this too (see below.) BTW, parted was willing to reformat the entire disk, AFAICT, but I didn't want to wipe out the installation I already had yet; I'll test it later, though I assume it will work. [The errors are the same whether in woody's parted or d-i's.] (parted) check Warning: The disk CHS geometry (1017,67,62) does not match the geometry stored on the disk label (3500,19,80).
