I have a client with 2 MyBooks attached to a Server 2008 machine. The drives detected fine for a year. Recently they are no longer detected properly. The Smartware virtual CD-ROM form the drive is detected and the drivers install. I attempted removing the drivers, restarting the server and reinstalling the drivers from the Smartware. The state was the same. The drive does not show up in disk management. The device manager shows the device in the hard drive section. I ran a chkdsk on the server and came up clean. The event log shows no errors concerning the hard drives.

The drives work fine on another workstation in the office.

Any ideas?
