Check the jumper settings on the drive-should be master by default, but you may have to either set it to Cable select for your case, or no jumpers at all...
Take a look at how the previous drive was jumpered.
Do you have Toast? If the drive is configured correctly, it should show up there, with model number of drive. Otherwise try PatchBurn, instead of the hacked plug-in file, to enable Finder/Disk Copy burning...
Check the drive database at Xlr8yourmac.com for tips on your particular Lite-on, and Lite-on burners in general...
I just checked drive database-your model is natively supported in 10.2.8 and Panther, at least installed internally...also at least one report of success in external firewire case...
