Software tool to monitor hard drives and logical disks activity. A small indicator on the screen will blink the same way as a hardware LED on a PC. A good replacement for the hardware HDD LED, especially when your pc case is not directly visible.
HddLed Indicator includes an All-in-One mode, where all drive activity is monitored on a single indicator. The program uses little system memory and CPU time. Additional modes provide indications using the keyboard ScrollLock LED and an icon in system notification area (tray).
