I am upgrading a FC2 to FC3 and using a 350 mhz Asus P2B motherboard with an IBM IBM-DTLA-305030 disk (30 gig drive). When I try to upgrade it looks like the upgrade tries to read the disk geometry and then gives an error : Assertion(heads>0) at disk_dos.c: 485 in function probe_partion_for_geom() failure. Has anyone else run into this problem with upgrading ???? Or does anyone have a solution to this problem.
