Sorry if you get multiple copies of this--I have tried sending twice
already and have yet to see it on the kernel-list.

Here are hdparms for all my devices--

Everything is working great! I can access my hard drive quickly, both
CD drives are working and I can read and write to my zip as a
partitioned drive or as a block device for Tar archives. Thanks for all
of the help.
