[ltp] Hard drive constantly spinning down

[Bill Sheppard]

I just replaced the standard 40GB drive in my T42 with a Toshiba 60GB
drive.  Upon booting it appears the drive is spinning down after only a
few seconds, as almost every command I type is followed by a slight
delay, and then I hear the drive spin up.  I've tried "hdparm -B 255
/dev/hda" to turn off APM on the drive, but this doesn't seem to help. 
I also think the drive may be operating far slower than it should - I
tried a "hdparm -t /dev/hda" and only got about 30MB/sec.  If I'm not
mistaken the old drive got over 100MB/sec, and this drive in it's
previous laptop (Toshiba Tecra S1) got around 100MB/sec as well.  Here's
my hdparm -I output:

Anyone have any ideas how to resolve this? 

Thanks!
