I have one, but apparently it’s for differential controllers and differential drives only, and of course, it’s not working. Before I drop some more money and time on this, do these things actually work?

Also, if it does, do I need to get one that’s terminated, or does it use the drives termination?

I’m not too up on SCA but do you mean one of [these](http://www.mcpb.com/html/sesca02.html)?

They [should](http://www.seagate.com/support/kb/disc/sca.html) work just fine.

Can you say which exact pieces you’re trying to connect?

As for terminators, with SCSI it’s easier to have a seperate terminator on the cable.
