Both drives are external, and they both have terminators on the back. The setup is like this: The DDS autoloader is connected to the back of the Adaptec card via a new external HD68 cable and the terminator that came with the drive is on the second plug of the unit. The Sun DLT drive is connected via an external HD50 cable to an adaptor that turns it into an internal cable which is then connected to the Adaptec card internally. It has a Sun terminator on the second plug on the unit. The cable that connects the DDS autoloader is brand new. It's not a major brand name, but it's listed as "double shielded", "UL20276 listed", etc. The cable that connects the DLT unit is an older Adaptec one (possibly used) purchased for a few dollars locally. I could understand if that cable was a problem for writing using that drive, but having the issue on both drives like this with two separate cables just seems like it's something else. By the way, the green LEDs on both terminators are illuminated so they should be working. With the DDS drive, it does not give any errors to /var/log/messages like the DLT drive does. cpio just quits with that "Internal overflow, aborting" error (which doesn't happen with the DLT). Do you guys know specifically what that message means? With the DLT drive, cpio actually gives the volume full errors but with the DDS it's only "Internal Overflow" and nothing else anywhere that I can see. Internet searches for the "Internal Overflow" message have not turned up much helpful information.
