Will not recognize external HD
PowerBook G4 Aluminum 12" 1.33 GHz
System 10.3
320 GB HD
1.256 GM Memory
Recently upgraded the optical drive to a DL superdrive (profiler says Disc Burning-Not supported, what's up with that????)
Plugged an external 1 TB drive via USB (external HD worked on the MacBook, System 10.5, minutes prior).
The PB won't recognize it (no Icon on desktop nor shows up when I open the internal HD window).
However it does show up when I run Disk Utility but still won't mount. Also Disk Utility won't allow me to repair it. It was configured on system 10.5.
Any clues?
