Our O.S. is Suse8.1 the output of the dhparm is: hdparm -v /dev/hda /dev/hda: multcount =3D 16 (on) IO_support =3D 1 (32-bit) unmaskirq =3D 0 (off) using_dma =3D 1 (on) keepsettings =3D 0 (off) readonly =3D 0 (off) readahead =3D 8 (on) geometry =3D 15017/255/63, sectors =3D 241254720, start =3D 0. --=20 Thanks, Ami.
