Well, you can avoid the "other" devices by first checking for a handler
task (disks always have them and devices only sometimes do) and if you 
find it (the handler) try sending it an ACTION_INFO to see if it thinks
it is a disk. The heuristics can get really complicated because the concept
of device "type" is not really embodied very well in the system. (Same thing
with serial type devices try enumerating them sometime :-)) Anyway, there
is a gross way of finding the device from a Volume node, look at the 
task pointer in the volume field an compare it with the various devices
that you found. I am not sure but I think that is how I did it with my 
"AmigaLife" file requester. I'll check tonight to see.
