Okay. Here's the scenario: Dell OptiPlex GX1 PIII-500 circa about June 1999. Came w/ one Maxtor 10G IDE hd. I presume it is UDMA/33 capable, not sure about 66. Using hdparm (doesn't matter what distro, as SuSE, RedHat, Mandrake, Storm, Debian, etc. all return similar results on these hard drives), this drive (/dev/hda) will jump from about 3-5MB/sec to 19-20MB/sec by enabling 32-bit I/O, and DMA. Fiddling w/ any other options just makes the speed go down (relative to 20MB/sec, not 5MB/sec). The second hard drive is a 17.2G Maxtor, circa December 1997. Not sure what the rating is on it, but I _think_ it was ATA33. This one is the problem child, per se. Straight out of the box, w/ any distro I've fiddled w/, this drives transfer rate is btwn 1-2MB/sec. Again, the only options that seem to make a significant positive difference is the 32-bit I/O, and DMA. But even so, the speed only goes up to a blazing 3MB/sec, tops. I've gone thru the hdparm man page, tried a bunch of different options, and I've never gotten any better than that, which is kind of depressing.
Any ideas?
