If you turn a drive on or off after your computer (the bus master)
is turned on, you may mess up the devices with active terminators.
They've assessed the position and decided if they're terminators
already -- if you then change what's turned on and what's turned
off, you'll upset them.

Always turn the computer on last and off first.  It's the bus master.

You may find that your problem goes away if you just add an external
terminator to your chain.  Active termination is always tricky.
