I often use an old PATA dvd drive for ripping dvds. It is connected via a PATA to USB adaptor to a USB port. It works perfectly with my OS (Win 7), but the drive doesn't show in AnyDVD (I: in the attached picture). Both DVD Shrink and CloneDVD2 can see the drive. My other external usb dvd drive, connected directly to a usb port, works fine with AnyDVD (G: in the attached picture). I tried both USB2 and USB3 and even tried the "Aggressive scan for drives" option. It's NOT a big deal as I have 2 other drives, but I'm just saying..
