I got the (disc) manufacture's utilities (which run on a bootable FreeDOS CD) and ran every test over and over. It kept telling me the disc was fine. I should have believed. I always feel a little weird about discs because although the manufacture and the BIOS agree on the geometry, FreeBSD always (over three or four boxes with a half-dozen different discs) tells me the geometry is wrong. It seems so confident about it, I generally let it do what it wants. But what does FreeBSD know about the disc that the manufacture and the BIOS don't? -- Lars Eighner http://www.larseighner.com/index.html 8800 N IH35 APT 1191 AUSTIN TX 78753-5266
