Do you have proper termination of the 68pin channel. Wide-SCSI is extremely sensitive to this and I find many people using Fast-SCSI without a terminator don't notice problems until they introduce a Wide drive into the mix. FWIW I have a 2940UW with two Ultra-Wide SCA drives using SCA to 68pin converter. I couldn't access the second drive unless I enabled termination on the second drives SCA converter. Michael.
