Detect Hard Drive Problems on MacOS X

SMARTreporter

S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a technology built into most modern hard drives that acts as an "early warning system" for pending drive problems. MacOS X does exploit the technology, but only when the Disk Utility.app is opened and the particular drive selected. SmartReporter checks your Mac's hard drives on demand or on a regularly scheduled basis. For those people who are very heavy disk users, this may be a useful addition to the toolkit.

The major limitation of this program is that it supports ONLY ATA or SATA drives. SCSI and USB drives don't have the S.M.A.R.T. hardware to begin with. FireWire drives have the hardware but Apple hasn't yet written the support for it.

SmartReporter checks the status of the drive as set up by the user, and reports on any pending failures detected. It can also send you a warning via e-mail. It is possible that the program may erroneously report a pending failure, but there are ways to check this. The documentation recommends that the drive should immediately be copied and taken out of use. And if the report is accurate, it doesn't mean that the drive will definitely fail — but, better safe than sorry. Some drive manufacturers regard a S.M.A.R.T. failure report as sufficient justification to replace the drive; if it's under warranty this is a no-brainer!

The program is free, available under the Open Source MIT License. It require MacOS 10.3 or later.
