I just migrated from a Linux fileserver over to a Windows SBS 2008 fileserver. I didn't realize my MyBook wasn't supported before I plugged it in and set up a backup schedule. Interestingly, I got the error that the drivers didn't install correctly. HOWEVER, the MyBook was still recognized by the backup schedule, and the backup performed successfully last night. I came in this morning to troubleshoot the driver problem and found the blurb on the WD website that Server 2008 was not supported. When I look in Device Manager, the MyBook is tagged with a warning symbol. Yet when I look at Disk Manager, the drive appears. While it didn't have an assigned drive letter, I was able to assign one. Anyone have any clues why - if the drivers aren't installed correctly - I'm still able to manage and use this drive?
