I'm happy to have never seen that problem. ;-)
I have, but not because of the motherboard... but because of mis-
aligining the pins on the header of the old-style Disk II card.
That's interesting. Not the cause in my case though - none of the
drives had been disconnected or reconnected.
My Apple ][+ clone and my Apple ][c both became disk erasing machines
with this motherboard fault.
Last time I discussed this on comp.sys.apple2 or comp.emulators.apple2
was in the mid--late 1990's, and IIRC quite a few people joined in the
discussion saying they had all experienced exactly the same thing.
