One year ago a friend of mine gave me a brand new Western Digital My Passport Essential 500GB USB 2.0 Portable External Hard Drive as a gift. It was working just fine for about 1 month. Then, it started discoennecting itself automatically from time to time. Especially, when I try to copy big files from my laptop to the hard drive. I tried to format the hard drive, but it didn’t help. Do you have any idea how I can repair the HDD?
As a recommendation, use the DLG Tool to test the drive. Also try using a different USB cable and a different computer.
