Updating your smartmontools

A while back, I posted on how you could monitor your Intel SSD under Mac OS X using smartmontools.

With the addition of a new iMac to my home office, I again updated to the latest smartmontools (6.0 at the time of this post), but it didn’t have all the information about the Apple 128GB SSD that is part of the Fusion Drive on this new system.

This led me to the little known (for me) command necessary to update the internal database: update-smart-drivedb

Before:

Running the update:

After:

As you can see, even after the update, this SSD is not in the database.
