Changing HD geometry
Posted on 2008-10-10
I had a Linux server mainboard fry as well as a replacement, it turned out to be a PSU problem. Anyway, rather then waste any more money on it I acquired a Compaq EVO 600 as a replacement. Before trying to boot up from the original drive, I decided to hookup the Linux drive on the secondary IDE controller and use Partition Magic (v8) to verify everything and do a copy to the primary IDE drive so I would have a backup. When I boot up PM, it tells me the Linux drive geometry is different. It is a Quantum Fireball 30GB HD. The error message seems to be telling me that the EVO BIOS thinks the geometry is 240 sectors rather then the correct 255 sectors (lucky for me PM caught that). The EVO BIOS seems very limited from what I can see (it has a number of cryptic IDE options but none recognizable as geometry like any normal BIOS). How do I tell this stupid BIOS it has the geometry wrong and correct it? Why is it getting it wrong in the first place? TIA.
