I recently bought a 2TB WD green drive to backup a OWC Mercury Elite Al-Pro 2TB RAID 0 I bought since it doesn't have redundancy and needs to be backed up. I figured the most flexible and practical way to do this would be to use a drive. Happy with my Mercury Elite RAID from OWC I went and bought a Voyager S2 dock from them. I have a dual eSATA Sonnet Tempo Pro card and get very fast speeds eSATA. I am very disappointed to see whenever my drive in the dock spins down it is no longer able to wake up. Tech support at OWC says I need to change in preferences unchecking to allow disks to spin down. But I want to be able to put disks to sleep. The alternative is to return the dock and get a new one. Are there any recommendations for docks (or cheap enclosures even) that have sleep capability?
