My WD My passport external hard drive 1TB is not recognized by my computer. I also tried with other computers as well, but it is not getting recognized. I can hear some noise from WD external hard drive when i connect it with my computer. Besides the spinning sound i am hear some sound repeating after very few seconds (4-5 seconds). I can see the WD My passport drive under Disk drives under the device manager. Also there is option for safely remove hard drive. i have my important data in the hard drive. Also it is under warranty. i purchased it from India on 29 Sep. 2011. Please let me know what issues can be there with hard drive and how it can be solved.
