Download full free SmartReporter, the app warns you of some hard disk drive failures before they actually happen
SMARTReporter 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.
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.
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.
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.
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.
*** SYSTEM REQUIREMENTS ***
- Mac OS X 10.6.8 or later
- 64-bit processor (Intel Core 2 Duo or better)
*** LIMITATIONS ***
Because SMARTReporter relies on the S.M.A.R.T. implementation of Mac OS X, it only supports S.M.A.R.T. checking for ATA, SATA or eSATA hard disk drives unless you install additional software to enable Mac OS X to also check the status of some USB/FireWire disks.
Please note that a S.M.A.R.T. alert does not mean that your disk will certainly fail completely, nor can S.M.A.R.T. (or I/O-error checking) catch all possible disk problems before they happen - it's just a very valuable indicator. SMARTReporter is NOT a substitute for regular backups especially as it only concerns itself with hardware-level problems (like physical drive failures) and not at all with software-level problems (like filesystem health) that could also destroy all your data. Perform regular backups and make sure you read all the documentation and the F.A.Q. entry about prediction reliability.
