We have a server running server 2003 and have set up Acronis to do image backups. Originally we tried using an ESATA card with the Vantec dual docks and experienced lock-ups when changing the drives. We make sure to eject & power off before ejecting. When the new drive is swapped in and powered up the system becomes increasingly bogged down and ultimately unresponsive. Even in USB mode the drive dock will work once or twice after reboots and then the lockups will happen.
Need to stop this from happening!
