Our school had a square looking one, kind of like a hole puncher for paper but the end was a bit different and you clamped the disk in.

I had the problem the other way around covering the hole making it appear as a DD disk :lol:

In the later floppy days putting a hole in the disk worked well, I presume at this point all the internal magnetic disk bits were the same, however when floppies were the new thing it did not, I remember looking into it and it was all to do with magnetic coercivity which is why it seemed to work at first and then fail after a bit :cry:

I remember reading about some bloke doing this with modding 5/14" disk drives flipping them over some legal crap involved, weird story probably in Wikipedia somewhere :lol:

I think the actual magnetic media read and write currents were different from HD to DD...

I half recall trying this back in the day, but I don't think it ever worked.. the DD medium was just to crappy for HD... Though I think it would work okay the other way around which would seem a bit pointless :lol:

I had to do this but I can't remember why now, but it worked, I think I was messing about with disk images on a A500+ and it was giving me grief about it for some reason, this solved the issue :lol:
