I have had two Quantum drives basically eat themselves (the sound they make is like an old window shade spring suddenly snapping back with a 'whirr' noise). They have been UDMA drives, running on an Asus MB with a K6-233, and Debian 2.0 running the default kernel. So I am very much interested in what you report!
In addition to the hdparm params you suggest, I wonder if you would be kind enough to list some of the BIOS features that are also suspects in this UDMA conundrum? In both cases that I mentioned above I had turned off the 'auto' UDMA detect, so that the drives were being recognized as just LBA, Mode 4 (is that right?, my memory is foggy here...).
Thanks a bunch,
