I am connecting the drive the a Linksys E3000 router as NAS.  When the drive sleeps, the router will not wake it up when accessed.  Is there a way to disable the sleep mode on this drive?

Try installing the smartware software and within this you will be able to configure the sleep options for the drive settings.
