Actually about six months back or so I did a relative speed test using a 
series
of different UDMA drives on an enhanced system under various O/S platforms to
see if anything had changed since the last time. Under *certain* conditions,
that axiom no longer applies. However, I also willingly admit, despite doing a
*lot* of skull-banging, I haven't figured out why, or for that matter, what 
has 
changed in how hard drive parameters are recognized under Linux.

For example, under Mandrake using a fast high-speed 40 gigabyte drive, in
approximately 40% of the time it was recognized by Mandrake as a fast drive, 
and
deployed appropriately. If the slave was *also* a UDMA drive, it, too, was
configured correctly. Even a lowly Iomega Zip Drive was configured as a fast
access drive. Go figure, sez I. I even tried it using several different brands
of drives, since I was neither scientific nor exacting about it. <sigh> When 
it 
worked it was a thing of marvel.

However, just now having stuck my foot so nicely into my mouth, I couldn't 
then
account for the other 60% of the time when one or both drives were recognized
and configured as pokey slow EIDE drives. I repeated this test four or five
times, and even had a fast drive be recognized two *different* ways several
times. I know instinctively it is in the libraries somewhere, but I don't have 
a
clue.

FWIW, I was able to replicate the same test results using Micro$oft Windoze 98
and backwards a time or two. For the most part, Windows 98 Second Edition and 
upwards recognizes the drive geometry correctly every time. <sigh> 

Can I buy an axiom now? <grin>
