Hard drives (and solid state drives) are the most failure prone components in your Mac. For that very reason, in fact, drive manufacturers have built in self monitoring, analysis and reporting technology right into the drive. (a.k.a. SMART) Most utilities barely scratch the surface of this information, simply reporting the bare essentials: pass or fail. Too often, once the overall failure has occurred, there isn't enough time to get important data from the drive. With Drive Scope you can see into the health of most any drive connected to your Mac.
With Drive Scope you can see the complete picture of your Drive's health. Granular information about each aspect your drive is monitoring is available for review. See each of the attributes that contribute to the drive's health - in detail. See which attributes contribute to overall failure versus those that are merely informational.
Control over Testing
Typically, a drive will check it's SMART attributes whenever it is convenient. With Drive Scope, you can manually trigger the drive's internal tests to make sure the SMART data is as up-to-date as possible. Check how long since the last time the drive ran a test with the drive's testing log.
When you first open Drive Scope, an information page is displayed, summarizing all the critical information about your drive. See Drive Scope's advanced health assesment at a glance, along with the number of errors encountered, as well as model and capacity information specific to your drive.
