Portable Hard Drive

I have the same problem, but i tried every thing, but there is an error message "Location is not avaliable: F: drive is not accessible.




The request could not be performed because of an I/O device error". the drive is show on device manager, and the partition wizard found the drive, but it recognize it at “bad drive”, but the drive light is on is sounds good and work and i  have run it on windows 7  on  another laptop it also give me the same error message. I hope to find a solution, the Passport carry every thing…
