Restoring a vhd image from My Book 1TB external drive to Windows 7 Pro

I save all my backup images on my WD MyBook external drive. When using Windows 7 backup & restore for finding  my vhd  image the program prompts for a WD driver. The Device Manager shows disk.sys & prtmgr.sys but windows never accepts those drivers. Then states “Restore failed”. Is there a specific driver disk WD provides with acceptable drivers Windows restore will recognize.
