For most drives the following will work (make sure to switch to “Performance Mode” in the BIOS, when using a Thinkpad):
eject -vx 0
0 disables any limit - you could also enter a speed (to test it is working choose something like
8 and the disk should spin down).
But as always: Some disks drives (PIONEER - use
cdvdcontrol -d /dev/sr0 -s to check for supported features) won’t respect that and their firmware needs a kick in the b*** -> run (package
cdvdcontrol -d /dev/sr0 --pio-limit off --pio-quiet perf
To disable any noise limits (take a look into the manual to revert that, as it is very bad during watching movies)!
