Right now I have my own problem. My floppies have gotten so old they Don't boot Workbench.
I bought a crusty game off of ebay recently and it dirtied my floppy heads causing read issues on most of my disks. Out came my head cleaning disk with 5 drops of cleaning solution and hey presto - problem solved. There's some head cleaning programs on aminet for those who aren't sure about where to obtain such software.
This game I bought was 'tested'... yeah right... the disk when inserted sounded horrendous and had more read errors than a retard reading Shakespeare. I was surprised when he actually wanted it returning! I got my refund luckily.
