FUD.
Works great for me in an A2000, also in an A500. Suggest it may be a problem with the controller board, or not set up correctly for LUN's, or some other configuration error (ID, termination, etc.). The A2091 isn't exactly the best SCSI controller option for an Amiga...
LMAO Paul doesnt do "FUD" that is just dumb. Its based on his experiences. Having said this it looks like there are several ppl here sucessfully using that hardware
