Running Windows Vista. HP Laptop. Acronis Trueimage and ShadowProtect (Trial version) works perfect and finds and locates all my hard drives, including my USB hard drive. But Paragon, Macrium and EaseUS Rescue Medium fails to locate and pick up my external USB hard drive..and Paragon freezes up and refuses to load when I turn on my USB hard drive.. and Macrium fails to even pick up my C: drive when booting the rescue medium to restore a saved image. ATI and SP proves that descent quality programs WORK and the free ones do not. As the old saying goes, you get what you pay for.
