recently I added new hard drive to my computer (1Tb) after that I'm noticing high activity of my hard drive. Only process running I can see in task manager is vsmon.exe and it's taking around 10% of CPU power. This strange disk activity usually lasts 2-3min and it's almost impossible to work with computer. It repeats often and also startup and shut down of computer takes extremely long time. Any idea where can be a problem?
