Hi,
I found this command called hdparm that looks at your hard disk. I found
that my drive had buffering off and Direct Memory Access(DMA) turned
off. I don't know what to do armed with this but ...
You could also look at
www.linuxdoc.org. They have a section
HOWTO/Multi-Disk-HOWTO.html that tells how to optimize if you have more
than disk.
Hope this helps,
Eric:-)
