Then you have a problem that _will_ pop up :)

Termination should be _only_ at the ends of the SCSI cahin. It's use is to
prevent refelections at the end of the cables. if you terminate each and every
drive, you might cause your SCSI bus not to function any more.

Note: In a non-ideal environment with a particularly unstable SCSI host
adapter, there have been reports of actually _needing_ a terminator in
between (most likely because two cables were used that didn't have
the exact same capacitance/resistance values, thus leading to reflections
at the joint of the two cables).
