How to turn USB HDD properly off when shutting down OSMC

[the_bo]

Hi

I had this issue too did not like the sudden click from hard drive did not sound good. What did was run hdparm in a shutdown script now it powers down gracefully. Make a script file with the line

hdparm -y /dev/sda1

Your hard drive may not be sda1. Run blkid in ssh to see dev name for yours. (Usually is sda1 with one hard drive attached)

And place it in /lib/systemd/system-shutdown

Startup and shutdown scripts - run script at earliest and last opportunity?

The hard way: write your own systemd unit file. The easy way: Startup: /etc/rc.local Shutdown: put your script or symlink in /lib/systemd/system-shutdown/ (fyi that is really right before halting the system. Filesystems e.g. are already read-only when scripts in that directory are called.

Hope this helps
