Surprized no-ones mentioned 'DBan' - running DBan to wipe that hard drive (you mentioned make, but Not model ID) would remove ANYTHING on that drive (excepting damage area of course) that may be interfering w/ W98's install process...DBan also gives a pretty comprehensive log file output if anything is preventing it wiping clean any area of the drive. Read Dban Warnings Carefully About How To Only Wipe The Desired Drive, personally I don't use it unless ALL drives are disconnected (Hard, USB, Sandisk, etc except floppy or CD) except the 1 drive I want to wipe. (Current vers are intended to run from a CD/DVD, versions 1.06 and back could fit on and run from a floppy...mmmm... seems 1.06 and back are not downloadable from sites associated w/ the author, looks like you may have to burn it to an optical disk then...) After its wiped the drive, Fdisk & Format per normal, then install W98. Incidently, you're installing W98 fm CD? might be better off installing W98 from a Hard Disk (and a hellva lot faster) e.g. http://www.inanis.net/blog/index.php/techie/install-windows-9598me-from-scratch/ . EDIT - I take back the first statement- DBan won't wipe a Host Protected Area (HPA) (and won't check HPA presence/absence) >and won't wipe a Drive Configuration Overlay (DCO).<?. (CMRR Secure Erase {HDDerase} ver 3.1 & later will check for HPA/DCO, and asserts it will attempt to wipe HPA/DCO [although my reading of its documentation suggests it may not succeed if a user or master password to Unlock the drive is not known].)
