Wow that drive looks bad. Looks like you could almost take the platter out and use it as a vinyl for a DJ. 
With scratches that bad, I'd be surprised if the head hadn't been ripped clean off by now. I think my drive may have had a head-crash too since my mac won't read it. (Diagnosing the LED flash codes have indicated that it probably is a head crash).
But aside from the usual noise an old drive like this makes, I haven't heard any unusual noises from it. I probably won't find the same kinda of disaster yours went through when I eventually open mine up. (which I only plan to do once I determine there is no way to format and use this drive)
As for the floppy drive, if cleaning it didn't work, perhaps the heads are magnetized. I heard that could become a problem with drives this old and cleaning them won't solve that problem. If it still doesn't read discs after de-magnitizing the heads, I would assume the heads are toast and the drive is a write-off. Part it out and find a replacement. It's probably not worth fixing it at that point.
