I have 64 bit Windows 7 Operating System running on my system and have a WD External HD that I have been using for the past 8 months on my OS Win 7 32 Bit laptop. It works all right on 32 bit, but when I attach it to 64 bit OS of Windows 7, and then my OS Win 7 fails to identify it and says "USB not recognized". The Disk Management is not showing the External Disk at all. There are no letter Conflicts between Laptop Drive and the External Drive separation. I have updated using Windows Update, and have installed the Hotfix from the Microsoft support. The Drive is Working fine; itís an OS of Win 7 64 Bit Problem. Please suggest a fix for this so that my External Drive can work properly.
Thanks in advance for any help with this issue.
