When something goes wrong, we might get a pop up notification or a crash report.
When email arrives we get a little number in the Dock’s Mail icon. With Growl installed, we get an unobtrusive pop up notification that something has happened (updated, synced, finished, whatever).
What we don’t get is notification from anyone that the Mac’s hard disk drive is chugging away doing something important (or, not).
Disktivity is an inexpensive Mac app that tells you when the disk drive is busy reading or writing or searching. The indicator light lives in the Mac’s Menubar.
The icon changes color depending on the disk’s status at the moment. Gray means the disk is idle. Green means the disk is reading. Red means the disk is writing.
Yellow means the disk is busy reading and writing.
Isn’t that wonderful? With just a glance you can see your Mac’s disk activity. If Spotlight is busy indexing, you’ll see it in the indicator light. If Time Machine is busy updating, you may see it in the indicator light.
While Disktivity is handy and perhaps useful, what it doesn’t tell you, and what I’d really like to know, is which app is using the disk to read or write at the time.
As it is now, Disktivity is a glorified light bulb with different colors for different functions, but doesn’t provide any real indication of what’s doing what.
That would be worth a few dollars.
