Spun down?

Overall this commit message needs some serious improvement.

I have no idea what Synology NAS with "deep sleep" support is.

We don't add support for vendor specific features.

Please reference the proper ATA ACS / AHCI / SATA / ACPI specification,
including the version of said specification and which section in that
specification.

Kind regards,
