Termination of SCSI devices on the SCSI bus is done to reduce false signals
that can cause your computer system to act erratically.  

Although I find it weird that it only occurs while idling, It wouldn't hurt to
put a terminator on it.  I am sure you could take the terminator back for a
refund if the same results still persist.
