Disk Activity Light
Without a disk activity light you have no way of knowing if anything is going on in a system if nothing is happening on the screen. There might be a legitimate system update that's just taking much longer than you expected, or there might be malware (virus) wreaking havoc. You can open Task Manager to see what's happening (on the Performance tab), but that's not as convenient and persistent as a proper disk activity light.
A good substitute for a missing hardware disk activity light is the small freeware DiskLED. It will reside in your System Tray and light up (as in the picture) whenever there is disk activity on any drive. Thanks to excellent design, DiskLED can also be used to monitor other system activities. It can even be used remotely.
