If you want to track the activities on your hard drives, then DiskCountersView is an useful freeware tool. DiskCountersView displays the system counters of each disk drive in your system, including the total number of read/write operations and the total number of read/write bytes. Apart from this, the application also displays the general drive information, like disk name, partition number, partition location etc.
DiskCountersView doesn’t require any installation process or additional DLL files. In order to start using it, simply run the executable file. It lists out all the hard drives on your PC including removable drives (only on Windows 7) and shows the read/write count, read/write bytes, total time used and other general information.
You can also set the application to automatically refresh the counter. Apart from this you can also export the result into HTML format. There is also option to reset the counter.
This utility works on Windows XP,2003, 2008, Vista, and Windows 7.
