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.

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".

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.

- Mac OS X 10.6.8 or later
- 64-bit processor (Intel Core 2 Duo or better)

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.
Some internal disks do not support S.M.A.R.T. at all and therefore do not work with SMARTReporter:
- the "OWC Aura SSD for Mac Pro"
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.

Valuable Info when you need it the most

I’ve been using SMARTReporter for years, it usually just sits in my menu bar, unnoticed but today it turned red and i got a desk-top notification that my drive might fail soon.
Valuable information for sure, even though i keep regular backups, it’s still a hassle when your drive dies on you out of nowhere…
There is a service many of you may not be aware of however, you can send a report when the icon turns red and before you know it, you receive an email with a thorough and easy to understand evaluation of the info gatherd by SMARTReporter.
It turns out i don’t have to run right out and replace the drive today, but i do need to keep an eye on things, and look to replacing it in the near future.
Kudos to the developers of SMARTReporter and thanks!

Always know the status of your drive. One of the few apps around that are capable of giving you good and instant info on your SSD.

Saved my data

(I have a spinning disk magnetic drive)

SMARTReporter alerted me to an I/O error. By itself, an I/O error doesn't mean that a drive failure is imminent, but it kept happening and my MBP was getting slower. I used the SMART tools and tests to discover that the drive was encountering bad clusters. Over 3 days, the drive went from 14 bad clusters to 39 bad clusters. Luckily, the drive did not exhaust its spare clusters, but the rate of bad clusters was indicating a drive failure soon!

SMARTReporter gave me enough time to get a current backup. Then I got the drive replaced under warranty and a few hours later, I'm back up and running -- not a file out of place. Thanks to time machine and apple care I have a new drive and all my files. Thanks to SMARTReporter, though, I had time to make "one last backup" and got the drive replaced before total failure.
