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.

What Apple Should Have Done

This little program does the one thing that I missed when moving from the PC world to the MAC world. Every PC I had ever used had and LED letting you know when the Hard Drive was being accessed. For a good number of reasons this can be helpfull as and example in the case of my old Laptop, before my MACBook, I figured out that I had gotten one of the evil mail malwares that was sending emails to everyone in I had in Outlook. Also, it allows you to know that when you start a program that is taking a while to start up that in fact it is doing something. I use a lot of Adobe programs and sometimes after their updates it can take a with for the Adobe program to start and run. Now with this GREAT little program I don’t have to totally wonder if something is going on.

As my Title to this states, “What Apple Should Have Done.” Very basic and to me important.

Just right, no more, and no less...

This application has a simple purpose. It displays the state of the disk subsystem in real-time (with a ittle pulse stretching). That in and of itself is not an earthshaking big deal. What is refreshing and of note, is that during my ownership of this program, it was easy to install, it takes care of itself with no ongoing maintenance required, and I never have to worry about it.

To function correctly, and to not cause any trouble... That is pretty much what there is to say about this application, from the user side. But like all apps, it took quite a lot of learning to write this application. And I don't think the author gets enough glory for the effort to write a trouble-free application for Mac OS X.

I recommend this application.

Useful but with flaws

The update is annoying. When I click the update option, the process could not continue because the software could not be stopped for the moment. So the update could not continue. But at the same time, the software could not work as well. I had to force quit the software, and set to avoid opening the software when logging in in the system properties, and restart the computer.

Anyway, I think this is a fairly well established software. It compensates the lack of hard drive indicator on the Macs. Wish it could go well in future.
