Attached is a modification to a stock version of hdparm-3.3.
This is not the final changes proposed to this tool, but it will now allow
for setting UDMA drives with 'hdparm -X66/65/64 /dev/hdx'.
-X66 == UMDA2 -X65 == UMDA1 -X64 == UMDA0
hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 64 MB in 1.64 seconds =39.02 MB/sec
Timing buffered disk reads: 32 MB in 3.58 seconds = 8.94 MB/sec
