Your geometry is either 64/32/1006 or 255/63/143 depending on whether you have extended translation turned on in SCSI-Select or not. >PS: how does it `know' my geometry's bad? and why doesn't it tell me > the right geom if it's so smart? :-( Its not smart enough to determine the correct geometry, but its easy to multiply the geometry out and see if it goes beyond the end of the disk. -- Justin T.
