hello,

i'm experiencing extremely poor performance of my harddisk. it is a
laptop-disk, but it should be faster, i think.

laptop:/usr/src/linux/linux-2.6.9# hdparm -tT /dev/hda

/dev/hda:
 Timing cached reads:   1248 MB in  2.00 seconds =3D 623.16 MB/sec
 Timing buffered disk reads:   14 MB in 10.85 seconds =3D   1.29 MB/sec

laptop:/home/andre# hdparm /dev/hda

/dev/hda:
 multcount    =3D  0 (off)
 IO_support   =3D  0 (default 16-bit)
 unmaskirq    =3D  0 (off)
 using_dma    =3D  1 (on)
 keepsettings =3D  0 (off)
 readonly     =3D  0 (off)
 readahead    =3D 256 (on)
 geometry     =3D 16383/255/63, sectors =3D 30005821440, start =3D 0

playing with the settings did not help.

laptop:/usr/src/linux/linux-2.6.9# hdparm -X66 /dev/hda
		/dev/hda:
		 setting xfermode to 66 (UltraDMA mode2)
laptop:/home/andre# hdparm -c1 /dev/hda
		/dev/hda:
		 setting 32-bit IO_support flag to 1
		 IO_support   =3D  1 (32-bit)

laptop:/home/andre# hdparm -t /dev/hda
		/dev/hda:
		 Timing buffered disk reads:   14 MB in 10.75 seconds =3D   1.30 MB/s=
ec

here some more information:
dmesg:

Can anybody guess what's wrong here?

thank you,
