Most likely, your adapter does not provide termination. SCA drives have no on-board termination, so, in order to terminate your SCSI bus, you really should have termination in the adapter. The $2 - $5 adapters on Ebay and Amazon do not have termination. The least expensive SCA - 50 pin adapters I've seen with termination are about $20, although OWC did have some for ~$10 for a while. I think they're out, unless they restocked. Ideally, the upper 8 pins on the SCA drive should be terminated as well (SCA drives are wide), not just the 50 pins in use.
