It's better with this option, hdparm works now. Thanks a lot. /dev/hda: multcount =3D 16 (on) IO_support =3D 3 (32-bit w/sync) unmaskirq =3D 0 (off) using_dma =3D 1 (on) keepsettings =3D 0 (off) readonly =3D 0 (off) readahead =3D 256 (on) geometry =3D 58140/16/63, sectors =3D 58605120, start =3D 0 But I still have a problem of latency when the disk seems starting afte= r about 30 sec of inactivity. It's strange. I don't find any disk option in the ACPI configuration entries. Or perhaps it's the=20 ACPI_SLEEP experimental option. I'll try without it.
