SMARTReporter 3.1.0
MARTReporter is an application that can warn you of some hard disk drive failures before they actually happen! It does so by periodically polling the built-in S.M.A.R.T. status of your hard disk drives as well as performing other checks for "I/O errors" or R.A.I.D "degradation". The current status of your hard disk drives is always easily recognizable because SMARTReporter changes its icon (optionally in the menubar) from green to red if a problem occurs.
S.M.A.R.T. CHECKING
SMARTReporter periodically checks the built-in S.M.A.R.T. status of all compatible connected disks. S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a technology built into most modern hard disk drives that acts as an "early warning system" for pending hard disk drive problems.
I/O ERROR CHECKING
SMARTReporter has the unique capability to check the system kernel log-file for occurrences of dangerous "I/O errors" to improve the disk failure prediction accuracy.
R.A.I.D. CHECKING
SMARTReporter can automatically check whether connected R.A.I.D. sets become "degraded" or just "offline".
DISK SPACE CHECKING
SMARTReporter can also monitor the free disk space because a completely filled boot disk might lead to system lockups.
NOTIFICATION OPTIONS
SMARTReporter has completely customizable notification options for all four disk checks including notification via changing application icons, email, alert dialogue, on-screen notification (Growl or OS X 10.8 native), or by launching arbitrary applications / scripts.
ADVANCED OPTIONS
SMARTReporter supports a variety of advanced options and tools including automated S.M.A.R.T self-tests, scheduled S.M.A.R.T. attribute checking and plotting graphs of all acquired data over time. Please note that the S.M.A.R.T. self-test/attribute-check features aren't officially supported.
