I put a few guest OSes on mybook. So, when I need to do my work, I would power on the mybook and use the VMware workstation to start the visualization.
Since I would have to access mybook for a long period of time, and since working inside the virtual OS would cause constant read/write to the harddisk itself. I afraid that what I do would degrade the performance of mybook, significantly shorten the lifespan of it or worse, increase the risk of bad sectors on the mybook hard disk.
Is my fear warranted?
