[G4] Hard drive dropping off line

[Robert MacLeay]

I seem to recall reading that some external drives had firmware which caused
them to "sleep" when not accessed for a period of time, or conversely, when
they are so busy they overheat and go into self-protection shutdown.  It may
be their fault, and not your system's.

There were a lot of issues early on with Panther and FW800, although I
suspect you are using FW400; the faster drives are hard to come by.  Read
about the problem at http://www.macintouch.com/panfirewire.html
