Check your drive, clean it and replace the capacitors with ceramic ones. IIRC someone on EAB described exactly that procedure a few days ago.
A lot of drives were tested with Solid Gold and the best performer here was the Chinon FB354, which has no SMD caps at all. Never had any issues when running the game from UAE or HxC-Floppy, too.
Another option will be WHDLoad; I myself am eagerly awaiting Codetapper's upcoming slave.
Edit: Or Stingray's - whoever gets there first
