I read much about firewire before deciding to move from USB to firewire
for my ourboard devices
Firewire was supposed to be hot patchable but my M-Audio 410 claims hot
patching thier firewire will damage and render inoperatable both my
ports and ext devices
connections MUST be made or unmade with the computer OFF
Is the hot swappable claim of firewire just ad copy ? what other
firewire devices forbid hot swapping?
thanks
George

On my mac, if unplug or turn off a Firewire unit I get a message that
something was turned off wrong and there might be damage to something...
If I eject the hard drive like I would a CD the message doesn't come on.
I think all the FW units are a little different.

IEEE1394 standard specifies that devices are to be hot pluggeable.
The errror message above says that the computer cannot guarantee that
all changed data has been written to the removeable device before you
unplugged it. This is software only, or data. There is no damage to
hardware.

Thanks for that. I thought so but you know I always swallow a rock when
I unplug.

With Macs, you have to drag the icon of that drive to the trash so that the
FireWire bus will not expect it to be there anymore. After that, unplug at
will.

I'd sure be afraid to do that (until someone told me otherwise). In my
imagination, that means "erase everything on the drive."

Maybe so, but there are apparently some bus-powered Firewire drives that
can damage the Mac's hardware if you hot-plug them, despite the fact
that FireWire was designed for that to work. There are signs everywhere
at Berklee forbidding hot-plugging drives because of that.

There have been lots of documented cases of blown FW controllers on
Mac G4's when "Hot Plugging". Some were probably ESD though.

There was a string of Mac laptops, including TiBooks like mine, that
suffered from a FW defect, and that was the source of the blown busses.
It wasn't th fault of the drive, it was Apple's fault. Beyond a certain
date of manufacture one needn't worry about this, as eventually the
bitching got to Apple's brain, even as the warranty fixes impacted
Apple's bottom line, and action was taken to fix the buss. I waited to
buy my TiBook until the last "still boots OS9" 'books were near their
end-of-(sales)-life.

Does it say physical damage might be done? Or that data buffers might
be lost?

I think it depends on how powering is handled. Data is hot-swappable,
and because they push the technology heavily for disk drives and video
cameras, I suppose those are designed so they can be yanked and
plugged without damage.

Something like an audio interface generally has no compelling need to
be hot-swapped, so maybe they just didn't bother with taking care of
that end of the business in hardware, but dealt with it in software
(the documentation).

I'd trust what the manual for the Firewire M-410 says.

I've not used the external Firewire interfaces on my Mac G4 (yet) but, I just
got an external DVD combo drive for my PC. The manual states, "you can unplug
without fear as long as your not writing to, or reading from the drive." Really
has no pressing to your question, I just wanted to throw in some PC info just
for the heck of it.

Doesn't this go all the way back to the floppy disk? I seem to
remember having to click on something to eject the floppy (there was
no mechanical button an a Mack floppy drive) but I don't remember
dragging the floppy icon to the trash can.

Command-E would do it, or the end of a paper clip in the little hole.
