+     "@command{hdparm} is a command-line utility to control ATA controllers and
+disk drives.  It can increase performance and/or reliability by careful tuning
+of hardware settings like power and acoustic management, DMA modes, and caching.
+It can also display detailed device information, or be used as a simple
+performance benchmarking tool.
+
+@command{hdparm} provides a command line interface to various Linux kernel
+interfaces provided by the SATA/ATA/SAS @code{libata} subsystem, and the older
+IDE driver subsystem.  Many external USB drive enclosures with @dfn{SCSI-ATA
+Command Translation} (SAT) are also supported.")
