I have a hard disk in my computer that I use to make backups of my data. I do not use this disk otherwise.

How can I stop this disk from spinning once my backup is finished? Also how would I make it spin back up again before the backup takes place later on?

The drive is a regular SATA drive.

Umount the filesystem and then run hdparm -S 1 /dev/sdb to set it to spin down after five seconds (replace /dev/sdb with the actual device for the hard disk). This will minimize the power used and heat generated by the hard disk.

  This won't always work. For instance Rockstor will do a smart check frequently while using the control panel, regardless of whether the drive is mounted to anything. The best answer is unfortunately to remove it physically... or not use any program that might wake it up, including S.M.A.R.T. monitors.

To further build upon samiam's answer, you can set udev rules to do these things for you.

For this example, you'd have to fill in a file in /etc/udev/rules.d (ideally name it something along the lines of 45-sdX-power.rules to respect the conventions, but it doesn't really matter...), with the following:

ACTION=="add", SUBSYSTEM=="block", KERNEL=="sdX", ATTRqueue/rotational=="1", RUN+="/path/to/hdparm -S 1 /dev/sdX"

where you will need to fill in sdX and provide the full path to the hdparm binary (which hdparm).

This will automatically stop your drive from spinning after 5 seconds of inactivity whenever your laptop boots.

This is ideal for a dual boot disk (my case), and backup disks you only startup once a week or so (in which case just mounting it before issuing your backup will turn it on and it will be off the rest of the time).

As for hdparm -Y /dev/sdX, it is less useful here as it only stops the disk from spinning once, after which any access to the disk (like mounting it) will re-start it and you will have to issue the command again.
