Unless someone can tell me what these messages mean, they are useless to me, warnings or not. > If it worked so well, why not put NT back on the machine and try > running a battery of tests and diagnostics on the machine with NT to > see if it was masking a problem or not? I don't have any T&D software for NT. The smartctl utility looks very interesting, but I don't know to what extent I can trust it. > I don't remember ever losing data while using DOS...

No, but the support organizations of major vendors don't behave like ill-mannered schoolboys when they are asked to show some responsibility for their software. > Or they could cover the other bases...that perhaps BSD is saying > something that NT didn't report. Rest assured, they will not do that. They will cancel the FreeBSD rollout and return to NT. And I couldn't blame them. > Yes, obviously FreeBSD is worthless. Not worthless ... defective. On this particular machine, the SCSI problems are too serious to allow it to be used for any kind of production. I suppose a company could just swap out hardware over and over until it got lucky. Or it could run a different OS. I've been a bit luckier on my production machine, which has brand-new hardware. Still, I'm getting mysterious SATA errors from time to time, one of which crashed the system. As usual, nobody has a clue as to what's causing them, and once again, the Great Satan is the hardware. Even though the only common point between the two machines is that they are running FreeBSD, somehow four separate disk drives and two controllers must be magically failing simultaneously. > I know that I routinely scour the OS source code for problems when one > of our cobbled workstations acts up under Windows.

Tell me the exact part that is failing when I get these SCSI errors. > Really?

People with the same hardware ARE having that problem. But nobody ever resolved it for them, either. It was the usual story about how it must be a hardware problem. > Silently resetting without telling you? I'm talking about the quirks that the drivers take into account for different types of hardware. FreeBSD, like many other operating systems, _does_ contain special code to workaround hardware idiosyncrasies, contrary to the implication that only Windows does this and that it is somehow a Bad Thing. > Then what are the errors you're getting again? Well, they go on for pages. I posted them here once (long, long ago). Stuff like this ...

Others have already encountered this error, on the same hardware, as I recall from my newsgroup and Web searches on the subject. In any case, finding an identical machine today would be problematic. -- Anthony _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
