Re: External HDD: Incremental Backup? / Power down?
- Hmm, USB disks are treated as SCSI under Linux. So no way of using
hdparm for my purpose. There might be a SCSI-idle Kernel patch for
this task, but this is too much for me.
Does anybody know: If I free my IDE disk from the USB case and attach
it directly to a computer, then I will be able to use hdparm: Will the
-S setting remain or will it be deleted when I ut it back into the USB
case and attach it to - say - the linkstation? Think this voids my
warranty so I better ask if this strategy makes sense.
