The manuals tell you to do things right because they assume, obviously
correctly in this case, that you're too ignorant to figure out the right
method on your own.  The point of the battery connection procedure is to
keep sparks away from the battery where they might ignite hydrogen gas.

The SCSI cabling procedure intended that people would use proper,
individually-shielded signal lines rather then the totally unshielded
ribbon cable that one often encounters in SCSI hookups.

I find that Syquest disks are great for backup, IF you create a partition
that is exactly the same size as on the working disk you're backing up.
(Then the Finder will do a device-to-device copy.)  The nice thing is
that the backup is directly "mountable" as a structured file system in
case you need to examine it or retrieve stuff from it.
