Hard Drive space can fill very quickly especially with photos, music and video files.  Just installing all your favorite programs and games can fill up the drive as well. If you would like to add an extra hard drive or transfer your old hard drive to a new larger one, I can do this by adding a second drive or cloning your existing drive to a new larger capacity hard drive.  Today the going prices for enormous hard drives are fairly cheap:       320GB = ~ $100   500GB = ~ $120   1TB    = ~ $160   1.5TB = ~ $200  Did you know that a hard drive with less than 10% space left can cause  windows to crawl and crash? This would be the case where you would have  to transfer or migrate your old drive to a new larger one.
