Firewire Problem

[Joe Sporleder]

Hello,

I just purchased a Lacie FireWire Drive "Porche Designed" 160GB HD 
(FireWire 400) from MacZone. When plugging into my G4 tower at work it 
keeps disconnecting from the computer (1.25Ghz single processor, 2002 
model, Apple still sells this one on their online store for $1299). 
Every couple of minutes, the drive will disappear from the Finder, and 
I'll get a message complaining that the device was improperly 
disconnected. I connect a couple of older Lacie FireWire drives on this 
same machine, and do not have any communication problems with the 
computer.

I can take the problem drive and connect it to my previous generation 
iBook 900mhz G3 and use it for hours without any disconnect problems. 
Same FireWire cable is used on both machines. Any ideas why the G4 
might be having a problem with this particular new Lacie "Porche 
Designed" Drive?

Both the iBook and the G4 are running MacOS X 10.3.2.
