My Book Prto II and Windows 7 64-bit. No driver found

My “My Book Pro Edition II” 1TB does not work with my installation of Windows 7 Pro 64bit.  I am connecting via USB and Windows reports that it cannot find a driver.  I am unable to locate one on WD’s site.  Can anyone point me in the right direction?

Do you mean silver round blue circle LED?  If yes, it is MAC formatted.  Go to disk manager and format to NTFS.

Note, Backup data first.  All data will be lost.
