Is the drive knackered??? same with any games too!!
Or the disks you are using might just be defective, magnetic media often become unreadable after some years. As to the drive, those like to collect dust at exactly the wrong places (the heads). If you have the patience, take it apart and clean out the dust. However, your error description does not sound like an unreadable disk, AmigaOS normally tries to saw those into pieces (well, that is what it sounds like anyway). That said, cleaning won't do no harm :-)
