I found this old article (http://www.linuxdevcenter.com/pub/a/lin … dparm.html) while googling for ways to speed up linux, and it came out on top. I found that my hard disk was set in 16bit Mode, which meant it wasn't running as fast as it should, so I tried setting it to 32bit Mode, and it didn't work:
/dev/sda:
setting 32-bit IO_support flag to 3
HDIO_SET_32BIT failed: Invalid argument
IO_support = 0 (default 16-bit)
How do I get it set to 32-bit mode now?
BTW: In case it helps at all, here's the results of hdparm -Tt /dev/sda and hdparm /dev/sda:
/dev/sda:
Timing cached reads: 1794 MB in 2.00 seconds = 897.33 MB/sec
Timing buffered disk reads: 174 MB in 3.01 seconds = 57.75 MB/sec
/dev/sda:
IO_support = 0 (default 16-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 9726/255/63, sectors = 156250000, start = 0

If your drive is SATA, then remember that IDE <> SATA. The article you refer to was written before SATA was even invented.
