Dear to all, I'm new on linux environment so be patience with me. I have a helios64 unit with installed Openmediavault 6. When I reboot or turn-off helios64 (both from webgui interface that from power button) the hard disk ( 2 wd60efrx) make a cute sound from head. How can I check that heads are parked correctly? I don't want damage my hard disks   Best regards
