I'm tending to "certainly" agree.

There are other things to consider as well, such as narrow, wide, ultra,
and ultra-LVDT. Active termination and passive termination.

Is there termination at the SCSI card?

You said there was termination on the cable, but is there also on-board
termination on the drive?

No other drive on the bus has termination enabled?

One terminator on each end of the bus, no more, no less.
