I got this strange result after I installed Western Digital 1200JB 120G 8M HD:

Code:

hdparm -Tt /dev/hda

/dev/hda:
 Timing buffer-cache reads:   -428 MB in  0.00 seconds =  -inf kB/sec
 Timing buffered disk reads:  -214 MB in  0.00 seconds =  -inf kB/sec
Hmm.. suspicious results: probably not enough free memory for a proper test.

and I'm sure I've enough mem:
Code:
free -m
             total       used       free     shared    buffers     cached
Mem:           502        490         11          0         41        233
-/+ buffers/cache:        215        286
Swap:          964          0        964


What's wrong with it? Please kindly help! :cry:
