Macintosh Plus (M0001AP) boot chime loop
Posted by: macintoshpleasework on 2020-08-11 06:44:59
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.

May I suggest a SCSI2 SD 5.5 or floppy emu?

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 🙂

Sorry, I meant a 5.1....thanks cheesestraws.

That wasn't meant as a correction of you 🙂 a 5.5 would be a sensible option too, they're just trickier to get hold of in the UK and since OP has the enclosure, it would be nice to use it.

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.
