thought these settings might save somebody some time when setting up
this drive (7200rpm travelstar)
hdparm -v /dev/hda
/dev/hda:
 multcount    =  1 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  1 (on)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 16383/255/63, sectors = 117210240, start = 0

hdparm -c 1 -d 1 -m 1 -u 1 /dev/hda

which yields these results

hdparm -T /dev/hda
/dev/hda:
 Timing buffer-cache reads:  1416 MB in  2.00 seconds = 706.34 MB/sec

hdparm -t /dev/hda
/dev/hda:
 Timing buffered disk reads:  112 MB in  3.03 seconds =  36.93 MB/sec


pretty satisfactory imo
