The Cyberstorm UW scsi controller should be in the middle of your chain, with an active terminator at both ends. Ideally, you need a cable with at least 4 connectors, though I get by with three by using the active termination on the harddrive itself on one end of the chain. But since the Cyberstorm controller has no termination, you absolutely must have an active termintor on the end of the chain after the controller.
Try this:
Terminator<->Hardrive<->Cyberstorm<->Terminator
