IDE drives do sometimes support this (though the standard is very very funky for this), but SCSI? I've never stumpled across a mode page setting that allows for an auto spindown. The `od' driver supports spindown while the device is being unused. Supporting spindown while the device is open will requires some restructuring of the code. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
