Yes, physically it works, but the W8 does not support the auto-backup, whereby the software looks at what has ben saved already, and just saves the newly dated files, since last backup. There should be an updated driver as the HD is still under warrantee, but I cannot find one nor does Seagate apparently support this product, which is not an acceptable business practice. Does anyone know of a W* driver update for the Seagate FreeAgent Go 320 GB HD?
