You have a FastlaneZ3 with working scsi??? This is the first time I ever heard of it, congrats man. I have three and none of them wants to work besides as a memorycard.
Anyway, it should load 10MB/s in syncmode. You should have a little prog named "Z3Dmacontrol", If I remember it right, to "tell" the Fastlane that you have a Buster11.
FastlaneZ3 Drivers :-)
EDIT: Darn, Patrik beat me to it. :-D
