Hard Drive Indicator

Hard Drive Indicator (HDI) displays a system tray icon of your local physical disks. It has a 5 bar resolution for both read and write operations and uses small memory footprint with low CPU utilization. It auto-calibrates itself to ensure that the output is relative to the disk usage for the previous 60 seconds (Read and write scales are not relative); it shows a 'governor' to indicate whether the system tray icon is actually being updated. HDI is especially useful for situations where the (hardware) hard drive LED is hidden, missing or broken.
