Introduction - If you have any usage issues, please Google them yourself
hdparm provides a command line interface to various kernel
interfaces supported by the Linux SATA/PATA/SAS libata
subsystem and the older IDE driver subsystem. Many newer
(2008 and later) USB drive enclosures now also support SAT
(SCSI-ATA Command Translation) and therefore may also work
with hdparm. Eg. recent WD Passport models and recent
NexStar-3 enclosures. Some options may work correctly only
with the latest kernels.
