If you can hear the drive clicking, then the 68000's certainly working well.
How does "ill sounding noises" sound anwyay? The A500 floppy *is* kinda noisy, especially under the command of some trackloaders.
I don't know if you're using a 1084 or what, but try connecting it to a TV (using an A520 or the composite output) to see if you can get a picture there.
