Good old XCopy is quite good at resurrecting floppies with bad sectors, as sometimes the sector isn't actually bad at all, it can be that they were last written to on a drive where the heads were slightly out of alignment or even sometimes it's just a case of the sectors having being written in as custom format that the AmigaOS can't read and reports them as being bad when using the Amigas Format command...
Give XCopy a go it always worked for me...
