Hi,
I had an AmigaActive cover disk blow in a 56 speed drive within about 10 minutes of me buying the mag, it made quite a bang. Fortunatley the drive worked after I had dismantled it and cleaned the bits out, the largest piece was only about the size of a 50p piece :-o . I ended up buying the mag again just for the disk :-( . I eventually put the drive in my nieces PC and it's still going strong, I was just unlucky I guess.
