It might be a good idea to add a few "steps" to diagnose some problems. (Most likely to determine if your drive works with the Catweasel or not.)
IE:
If you can't get it to work after doing everything above. Then move the Amiga mountlists out and try only the "PC" mountlists. If that works, then try mounting the Amiga mountlists (after the bootup sequence is done) and test to see if everything works. If it does then you know your drive works.
In my case I had a drive that wouldn't work with any mount list (the unsupported "Mitsumi"). One that would work with only the PC mountlists (a panasonic). And a third that worked with both. However, the third one (a sony) did not seem to mount properly if I did everything in s:startup-sequence. I moved the Amiga mountlists elsewhere and them mounted them in user-startup. It seems to work reliably now. Unfortuantly I can't rigure out how to remove the drive faceplate to use it on the molded floppy enclosure.

P.S.
@redrumloa: when I unzipped the Dosdrivers, everything was readonly. I had to change the protection bits around. :-?
