FYI I Just uninstalled Magician after using it for almost 3 months. Under 4.4 now, my TI ZBook 17 would blue screen every couple of days, and the BlueScreenView program points to the RapidDiskFltr.sys driver every time. I guess there is a chance an SSD is failing as the blue screens occure when disk is being hit hard, but I doubt it as the laptop is 4 months old. I'll run a week or so and see if I Get any more BSOD, if not then it's buggy software and beware!
