I agree with several of the posters on here toss the drive and get a new one. You have several options.
One: just buy a used one off ebay and look for one that has a decent size between 2 and 8 gig is plenty.
Two: buy one from
AmigaKit and have the OS installed by them so all you have to do is plop the drive in and turn it on and your off and running with no hassles.
