At least I have performed that on a regular FB-354 (rev E?...) of an 
A500+ successfully. (This sort of problem seems to be very common 
amongst old A500s, especially if they had been stored in a less than 
suitable place. The drive that I fixed wasn't actually mine, I had 
bought it as a replacement from eBay, and had to fix it first before I 
could install it in my A500+). That one was at least fairly serviceable 
I'd say. Even the small microswitches in subject could be desoldered and 
taken apart pretty safely. (I was paranoid and disassembled them on a 
piece of white towel so that I won't lose any of the small parts :-), 
but otherwise, it was easy). The question left, is whether the drive in 
the C65 is a close relative of the FB-354. (I haven't seen that variant 
yet, so I can't decide, although I'd presume yes).
