Macintosh Plus (M0001AP) boot chime loop

Hi Nathanplus, thanks for your reply.

I have scanned the drive using Lido, and it does come up with bad sectors and it also fails to reassign them, which suggests a deeper issue. 

Formatting and initializing the drive using Lido completes successfully, but I get the same issue when trying to boot after a fresh install. 

 
To give a final (maybe) update on my Mac Plus - I'm happy to say that with the great help of cheesestraws providing boot disks, as well as a new floppy gear from Italy, it's now running nicely! 
Yay!  That's really nice to see.

What's that keyboard you've got on that?

Yeah, that smells to me a bit like your drive is on the way out.

You could pop another SCSI disc in that enclosure—they're not that rare—or you could put a scsi2sd 5.1 in there if you want to maintain the look but run from something new and solid-state.  (A 5.5 is more like a "thumb drive"; less useful here, as the Mac Plus doesn't natively power stuff on the SCSI bus—so you'd need a power wire to it anyway, or to mod the logic board in your Plus.  Personally, since you have the enclosure, I'd use that).

Personally, I really like the scsi2sd, but I didn't like storage with moving parts when it was new, either; other people feel otherwise :-)

 
Thanks for all your suggestions regarding the drive - I had the faint hope that drive would do the job, but maybe it is worth looking into the scsi2sd.

The keyboard is a Datadesk Mac 101. I'm not too knowledgable about keyboards, but It is actually quite nice to type on.
