The site Click of Death and The Charles Technique , does work. I inherited a Zip100 Internal SCSI drive for my PowerWave Mac clone. I never used the drive before and never had a Zip drive give me problems. I still have my original 1995 Zip that I used with Windows 3.1 and OS/2, and it’s still kicking. As soon as I put the disk in this internal drive, I knew it was bad. But I found this site, and it does work. Just remove the cover and go behind the rw head and it works.
