Steven, My first reply has somehow not made it to the list.
Check the BIOS CMOS setup. DOS has trouble with certain disk geometries -- like more than 1024 (?) cylinders. On larger disks, the LBA setting has to be used. Linux, BSD, SCO, etc. don't have a problem with limits on cylinder counts, but DOS and early Win9x do. LBA "lies" to the BIOS and reduces the apparent cylinder count while increasing the apparent head count to achieve approximately the same space but with a different geometry. I'll be interested in hearing what you find. ~~ Garry * [EMAIL PROTECTED] ----- Original Message ----- From: "Steven C.
