Yes, but I have a different disk: HTS726060M9AT00

# hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 65535/16/63, sectors = 117210240, start = 0

# hdparm -Tt /dev/hda

/dev/hda:
 Timing buffer-cache reads:   1796 MB in  2.00 seconds = 897.69 MB/sec
 Timing buffered disk reads:  100 MB in  3.01 seconds =  33.27 MB/sec
