I've had this disk in my machine since new (when's that? 3 years?), and I never had any trouble. Yesterday, after I built a new kernel, it started giving me trouble. No panics, just hangs from which it wouldn't recover with a bus reset. I rebuilt the kernel with the quirk entry suggested (sorry, forget who did it), and since then I haven't had any trouble. So: what caused it? Could be, of course, that it was a complete coincidence. But doesn't that make you wonder when it suddenly happens to a lot of people at the same time? Must be a virus.
