hdparm

Documentation

Overview

hdparm performs control operations on disks.

hdparm is modeled after linux command of the same name, using a command [switches] verb model, but many of the verbs are also switches which can conflict.

Upstream hdparm also decided a conf file in /etc/ would be a good idea; we have no plans to support that.

We also have no plans to support ata12. It's 2019.

Unlike the standard hdparm command, we do not allow empty arguments for commands requiring a password.

Synopsis:
