Hi Thanks for the quick reply, but unfortuately, no luck. I have done "hdparm -h" and "man hdparm" (I already had it, it seems), but very many of the features of hdparm (including all that seem to be relevant to starting/stopping/putting to sleep hard disks) are for IDE disks ONLY. These are "hdparm -y, hdparm -Y, hdparm -s, [/dev/sdb]" as far as I know, and when I try them, I get "operation not supported on SCSI disks"
