Official dumping guide recommends “write protect your floppies!”. When I finally bought 360KB floppy drive, first test revealed, that it reads 5.25" DD floppy correctly, but unfortunately its write protect sensor is broken, so it writes even to write protected floppies!

Because I can only clean drive's heads, I did not want to disassemble the 5.25” drive.

So I come up with an idea, how to make a read only drive again. So I modded PIN28 = Write Protect (signal /WPT) using a sticker and piece of wire.

If you have a better idea, please share ;)

So here's a better idea: How about a switch?

All my ideas were just to fix write protection of that 5.25", that something like a switch did not come to my mind :$ I will put the switch at the back of PC and one switch will protect both drives A: and B: altogether. Vice versa, without a switch I could not even write to the B:

I was also told that I do not need to isolate the PIN28 on the floppy drive, as all the lines are "Open Collector", so direct grounding is OK. Again I didn't think about it till now, but wires 1,3,5,7,..,33 (odd) are all GND. And it happen to me few times, that I plugged floppy connector the opposite - i.e. effectively grounding all the signals. So again, I already test it, without knowing *hehe*
