Currently my hdd setup is:
/etc/rc.d/rc.local: /usr/local/sbin/hdparm -m 8 -a 8 -X 34 -c 1 -A 1 -u 0 -d 1 /dev/hda
hdparm -t /dev/hda reports
/dev/hda: Timing buffered disk reads: 16 MB in 3.37 seconds = 4.60 MB/sec
yes, it have a good transfer rate ... but what is the PIO mode ? When I try with
hdparm -X 34 /dev/hda
/dev/hda: setting xfermode to 34 (multiword DMA mode2)
Bye!
