I'm helping someone who had a 6GB Western Digital hard drive(AC36400-00LC) go bad in his computer. The date on the drive is February 1998, so it's still under the 3 year warranty. The problem is that he doesn't have a receipt for the drive itself, since it came included with machine. He also doesn't have a receipt for the computer system. Will Western Digital still honor the warranty? Anybody have any experience returning drives to this company without a receipt.
