i have a sony external firewire cdrw, and lately it broke, so i was thinking to get an internal plextor cdrw to replace the sony, and i thought i can still use the external firewire case. The funny thing is that after i put the plextor inside the firewire case, my sony vaio can't recognize it, but if i put the sony internal cdrw back, it can recognize. So i have to get another ieee1394 firewire case.

Anyone knows how can i make my sony firewire case work? any firmware upgrade or sony made this case only for sony internal drive?

Thx
Ben
