I have a simple Ubuntu (12.10) server running with an external HDD attached to it. It is mounted regularly (NTFS) without RAID or so.
Because it is mounted all the time, the hard drives becomes very hot all the time, even when it is not used.
Is there a tool for automatically unmounting external HDs when they are idle and mount them when someone wants to open it? Or maybe there is another technology that can make this HD go to stand-by while mounted?
The last thing I can think of is making a CRON job to unmount and mount it at predefined intervals (during the night), but I'd prefer something more efficient.
