Most internal and external drives can be monitored for disk health using a monitoring system called S.M.A.R.T. Part of Disk Drill’s free data protection system is a way to easily show your disk’s S.M.A.R.T. status right from your menu bar.

Keeping an eye on your disk health is essential, because it can help you to take steps to backup your data or repair your disk before you suffer a catastrophic data loss. Once you turn on S.M.A.R.T. monitoring, you will always know your disk’s status with just a glance at your menu bar.

Turning S.M.A.R.T. monitoring on or off

The first time you launch Disk Drill, you have an opportunity to check a box next to “Monitor my disks for hardware issues.” If you did so, S.M.A.R.T. monitoring is already on and you should see the gear icon on your menu bar. If you didn’t, it is easy to turn monitoring on by going to Disk Drill > Preferences and selecting the S.M.A.R.T. tab. Simply check the box next “Monitor my disks for hardware issues” and you will be all set! To turn monitoring off, simply uncheck that box.

Turning on or off the menu bar icon

When you turn on S.M.A.R.T. monitoring, the icon is automatically added to your menu bar. It looks like a gear. You also have the option of showing the disk temperature (one key indicator of disk health) by going to Disk Drill > Preferences and selecting the S.M.A.R.T. tab. At the bottom of that window, check the box next to any disk you wish to display a temperature for. You will immediately see the gear icon change to a temperature indicator. The maximum “safe” temperature is considered 59 degrees Celsius (138 degrees Fahrenheit). The center of the circle to the right of the temperature indicates disk health by color: green means the disk appears to be healthy and red means issues have been detected. The outer rim of the circle indicates how much disk storage space you have left, ranging from green (plenty of space left) to red (almost out of disk space).

SMART status

If you wish to turn off the menu bar icon altogether, in the same Preferences window check the box next “Hide Menu Bar icon.” This does not turn off monitoring, but simply hides the icon.
