Can I automatically power down a usb external HDD.
I use an USB external HDD for backup only. I have the backup program scheduled to run at 2 in the morning and the backup takes less than an hour.
So the external HDD needs to be powered up only during that hour.
Is there a utility available that will "spin up" the drive when it is accessed and then "spin down" after an idle time?William Lockie
The first thing I would try is advanced settings under your windows' power profile. Then the drive's firmware may be configurable. You can get a utility which will access it. Seatools might, or check with the manufacturer.
