Hiya folks, I recently sold a Western Digital My Passport usb3.0 1TB Portable HD on Ebay which was working perfectly before I sent it - I formatted it in NTFS and did a full scan and no bad sectors were found just before packaging it up. The buyer claimed it wasn't working in any of his PC's or devices and the only sign of life was the power light came on when the drive was plugged in.

I have just had the drive returned and sure enough I cannot get it to be recognised on my Windows 7 PC or any other device - only sign of life is the power light comes on when plugged in. Anybody any ideas/tips on how to see if I can get this drive to be recognised??
