Guys I have tried all the solutions posted on this site, non has worked for me. My Passport 1TB Hard drive does not show on my computer, but shows in device and printers, it says the device had been installed correctly each time i plug it in. When i try to access it from the disk management it prompts 'you must initialise disk before logical disk manager can access it'. when i press ok, this pops up 'the request could not be performed because of an I/O device error. All my usb ports are working perfectly. i have important documents i need to recover urgently, is there any app that can solve this issues? i'm tired of cracking my head... please help. i use a 64bit HP Pro Book
