Check Hard Drive Spin State

  • Does anybody know how to check the Spinning state of Hard Drives ? I've set them to spin down after 10 minutes although they audibly don't sound like they spin down. I assumed the information would be In SMART but couldn't find anything ? Have I missed something ?

    Check out hdparm. Specifically "sudo hdparm -C /dev/sda".


    However some/sometimes HDDs can not be used with hdparm. I can't use hdparm on my Odroid HC2s with IronWolf HDDs.


    I go with the sound. And the short delay when accessing something on the drive while it spins up.

    Be smart - be lazy. Clone your rootfs.
