something similar on trying to upgrade to hardy from gutsy on one machine.

Sata drive errors. Only I don't HAVE SATA drives, IDE only.
BUT it is old PIII 733 using the Via chipset and have noticed that there are bug reports filed on that chipset. (oldest and slowest box in the joint!)

Went back to 7.10 till the issue gets solved for that unit. (and that may not be until 8.10 comes out in October!)

If it works, doan be messin' wid it!!!! It IS nice to have the fall back to a working system on that machine!
