Hi there,

hdparm in busybox-1.00-pre2 gives me

~ # hdparm -tT /dev/hda

/dev/hda:
  Timing buffer-cache reads:    84 MB in  2.08 seconds =  40.38 MB/sec
  Timing buffered disk reads:    8 MB in  3.82 seconds =   2.09 MB/sec

on my MPC8xx system.

But my original hdparm.orig v5.2 shows

~ # hdparm.orig -tT /dev/hda

/dev/hda:
  Timing buffer-cache reads:   128 MB in  6.35 seconds = 20.16 MB/sec
  Timing buffered disk reads:  64 MB in 27.39 seconds =  2.34 MB/sec

which I think is (more) correct!

Steven
