Hi,
nothing to do with Pismos, however, my FW ports on a QS 800 work
sometimes, some others do not ....
What do I mean with it? For a week or a month at a time the FW ports
mount drives, Card readers, the iPod fine, then suddenly I need to
power on/off/on or unplug/plug my FW devices several times, possibly
with Disk Utility open (I don't know why, but that seems to help, in
particular if you keep going to menu and do the refresh command a few
times). After a few days of misbehaving, everything goes back to normal
for a while. Well, I just learned to live with it.
Problems also seem to crop up after system updates and get fixed with
the following ones. I guess that FW, although enormously better for
than data transfer than USB 2.0 it is not as reliable for day to day
use. I'll take it any day, though, over the old SCSI and its proverbial
SCSI Voodoo;-)!
Down to your problem, I guess that 10.4.4 and FW in your machine don't
like each other for some reason ... can you go back to 10.4.3 and see
if it works?
From what you say you have two partitions, try installing OSX in the
second one from scratch and go 10.4 > 10.4.1 > 10.4.2 > 10.4.3 and so
on, see what happens.
If that doesn't work empty/back up one of your FW drives, remove it
from the case and install it in the Pismo (provided they are all 2.5"),
load a system and see if it works.
Try installing the drive in an external powered enclosure, see what
happens.
Plenty of variables, and potential causes, good luck.
Cheers
Andrea

ROFL "It's a computer, you're swearing at it; perfectly normal
behavior" I think I just found another .sig for the collection :->
Well, at this point you can tell that everything works, just not all
together.
Start random neuron firing:
Try resetting the PRAM on the Pismo. Since it's FWTDM capable, some FW
settings must be stored in the pram. It can't be the OS, since you
ruled that out.
Is this a bus-powered FW case? Is there an auxiliary power supply for
it?
My suspicion is that the FW ports are functional as data ports, but
something's causing them to not supply sufficient power to the case;
everything that *works* on the Pismo is self-powered: your friends
iBook, the iPod.
Not knowing how the FW cases are constructed, it may be that the
designers cheaped out, even if they have a power supply, perhaps the
FW interface itself is bus-powered, and the drive from the PS in the
case, if there is one (that way they can use the same circuit for both
bus-powered and self-powered devices.)
A powered FW hub would also sort this out if that's the issue.
Specs exist for the voltage/current that's supposed to be supplied b
the FW bus, a little time with a VOM should tell you what the Pismo's
ports are supplying.
And as a final note...my little bus-powered 2.5" FW case will behave
just like that when it's cold, such as when I've just come in from
riding to work in the morning: green light on, but no drive mounted.
Once it warms up it works just fine, and I HAVE had more issues
connecting it to my Pismo than my desktop systems, come to think of
it.
