Here's the output on my SATA drive:
# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 3832 MB in 2.00 seconds = 1915.88 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for
device
Timing buffered disk reads: 184 MB in 3.02 seconds = 60.84 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for
device
So it fails on some sort of IO command but still runs the benchmark.

How do I go about enabling DMA?
If the answer is reinstall how do I insure this won't happen

if your SATA drive is on /dev/hda then its not a SATA drive or you
need to
move from a 2.4 kernel to a 2.6 kernel and get real SATA support.

Dumb question, but can you still run "hdparm -t /dev/whatever" on a
SATA drive? No matter how it's configured, it would at least give you
a ballpark figure on if the drive is configured right. My system just
scored 11MB/sec while recording two shows and transcoding, and 40MB/sec
when it was merely transcoding.
