Drives Meter
Another very useful Gadget is the Drives Meter, made by the same outfit as makes the Network Meter. For anybody whose computer lacks an indicator LED for the hard drive or uses multiple drives, this Gadget does the job -- and more. It indicates when a drive is in use, gives an idea of how much data is being accessed, monitors writes and reads separately, and monitors logical drives separately. Like the Network Meter, it has lots of useful settings.
