Disk LED

By Raul Ignacio Verano

Open the Mac App Store to buy and download apps.


Have you ever wondered why your machine is not responding? Have you ever wished it had a LED indicating your disk's activity?

Well, now it does! Disk LED is a very simple unobtrusive application that lives in your status bar and displays just that: an indicator of your disk activity.

Disk LED shows activity for any internal or external storage device in a separate or summarized way (only for the devices you wish to monitor).

You can choose between many LED models to suit your status bar style, and overlay an indicator to know which of them are removable or optical drives.

Just hover with your mouse over the leds and you can see a tooltip to know which is which.

You can also change the refresh rate to decide how many milliseconds you can tolerate without knowing exactly what your disks are doing!

If you are experiencing any problems or would like to send us a suggestion, please contact or tweet us @agileroute and we'll be happy to help you.

What's New in Version 2.1

- Option to show contained volumes instead of disk model as tooltip.
- Fixed: some external devices didn't disappear when unmounted if "Ignore devices that doesn't contain any media inserted" is enabled.

Customer Reviews

Must have app!

Well, I like this app, it’s design and functionality, but it’s shame it hasn’t been updated since 2011 and when smart monitoring is enabled your mac won’t go sleep. So that’s why 4 stars, otherwise very good app. It will be good to keep updated for newer OS X versions to keep running without any glitches. Also you can host this app within CPU LED and you’ll get Disk, CPU and memory monitoring in once. I would be glad if author doesn’t drop development for this app.
