Hi Jiang,

Here's the output from hdparm:

<SNIP> # hdparm -tT /dev/hda

/dev/hda:
 Timing cached reads:   2520 MB in  2.00 seconds = 1260.54 MB/sec
 Timing buffered disk reads:  154 MB in  3.03 seconds =  50.76 MB/sec

and here's the output from bonnie++:

I'm reluctant to do the hardware swap again just to time the old disk.

The machine is a T42p 2 GHz Pentium M  1 G RAM 14.5" HD LCD display
running on line power rather than on battery.

Good Luck,

Don A
