From the developer: Is your computer's case hidden away and you can't see its drive led? Is your laptop missing a drive led? Would you like to be able to monitor the disk activity on some of the computers on your network? Then SoftLeds is the exactly the tool you're looking for. SoftLeds can monitor the activity of any number of disks on your machine and machines on your network. It does so by displaying icons on your tray area, each one representing a disk being monitored.

Note: The Demo version will only monitor one drive. The full version has no limit on the number of drives that can be monitored.
