Before LVD, there was differential SCSI

I have an HVD (High Voltage Differential) device. I was told that I need a differential SCSI cable in order for the device to work properly. I have never heard of a differential SCSI cable. Is there such a cable or is the tech grasping at straws?

I know the device is functioning properly. Granted, I cannot guarantee that the cable in use is the same as the cable used when the device was connected to another known working setup, and I am using an HVD controller in the new server.

Before there was LVD, there was only differential SCSI, now called HVD. Yes, you must have a differential SCSI cable for this to work properly.
