WD 1TB My Passport Ultra 1TB is not recognized and affects the operations of other programs when connected to my PC. My OS is W7. In My Computer the Passport Drive does not show up. It does appear in Device Manager as working and I tried to update drivers and got the message that the latest are installed. When I look for the drive in Device Manager not only does it not appear but no other drive including C appear. In reading other closed articles on this site I found out that I should buy a new cable and try that first. The drive when plugged in lights up and I can hear the drive quietly spinning away no unusual noises. I have tried it in another PC and 4 different USB ports. Hopefully the new cable will solve the problem. Any thoughts or ideas will be appreciated, thank you.
