Judging from the model number, you have a 45GB IBM DeskStar 75GXP, one of the first IBM drives to earn the nickname "DeathStar" for its high failure rate. What does IBM's Drive Fitness Test tell you? I'll see about performing your test tonight; I've got a hefty little DivX directory I can throw around as I wait for j2sdk-1.4.0 to finish compiling. Such a test should be sufficient... This could also be a recurrence of ye olde VIA686B PCI+IDE issue. IIRC, some VIA686B motherboards that had that flaw were effectively unfixable, simply because certain motherboard manufacturers spotted the problem before everyone else (even VIA?) and tried their own partial kludge fixes for it. Gotta love VIA. On Wednesday 17 July 2002 09:00 pm, J.
