Smartmontools

http://sourceforge.net/projects/smartmontools

smartmontools contains utilities that control and monitor storage devices using
the Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) system
build
into ATA and SCSI Hard Drives. This is used to check the reliability of the
hard
drive and to predict drive failures.  

smartmontools Version 5.x is designed to comply to the ATA/ATAPI-5
specification
(Revision 1).  Future releases of
smartmontools (Versions 6.x and 7.x) will comply with the ATA/ATAPI-6 and
ATA/ATAPI-7 specifications.

== CONTENTS ==
The original suite contains two utilities:

smartctl is a command line utility designed to perform S.M.A.R.T. tasks such as
disk self-checks, and to report the S.M.A.R.T. status of the disk.

smartd   is a daemon that periodically monitors S.M.A.R.T. status and reports
errors and changes in S.M.A.R.T. attributes to syslog.

I only ported smartctl, maybe smartd will be part of a future port.
