My original post here
Ok, I think I may have figured out what went wrong with Arklinux. It was my fault. I installed it at the end of a drive. I think that's what hosed the whole file system, on this computer. This time it's at the beginning of the drive, and I formatted the Linux partitions in Win XP with Partition Magic before I installed.
So, sorry Arklinux folks. It was my Boo-Boo not yours. Comments?
