My Book Essential P/N WDBACW0020HBK-00 was OK in Windows XP. In my new deskop, Windows 7 asked for SES driver. I downloaded correct version (64-bit) and it recognized the drive, but asked to format it. In Disk Management, it is RAW. However, when I plug it back in my old XP desktop, all files are there. I tried on another Windows 7 machine, and the same: asked to format.
How can Western Digital NOT write a new driver for My Book Essential? I need to use it in Windows 7.
