Yes, that was a real problem. The Amiga would access disks every time they were inserted to id them, but viruses too would use that feature to spread themselves; they would remain resident in memory (also after warm resets) then write themselves on the bootblock of every inserted floppy. Seeing the computer access every inserted disk was then normal, no way to know if it was for reading or writing, so back then I built a small device that would take the writing pulse on the floppy port, make it a bit longer and drive a beeper. If I then inserted a floppy and it started beeping that meant that floppy and the one I read before it were infected so that I could restrict the suspects list and clean them. It was very effective, built some for friends and also sold some of them on local listings.
