Though we have harddisk indicator on most of CPU’s build days which tell us the stat whenever is our system is idle, or when harddisk has started/stopped processing. But sometimes we have our CPU placed in such a way or led indicator damaged in such a situation we don’t know what’s going on or when our system is idle.

If this has ever happened to you then may be the Harddisk Indicator Pro can be very useful in such a condition. This  tool displays a red light at the system tray whenever your hard disk is in working state. This will enable you to make out the times when your system is idle and when in use. The colors are also customizable.

Though this tool is free to use it has a compatibility issue with Windows 7… so windows 7 users will have  a while before this fixed.
