I remember using Disk Doctor back in the day and it was near useless. The jokes about Disk Doctor and malpractice seemed to be everywhere. The only time it sort of worked for me was on a copied game that somehow developed errors. I ran Disk Doctor on it and it actually fixed the disk...or so I thought.
When I booted the game it actually worked but the sprites were all messed up. I was amazed that the Disk Doctor some how repaired enough of the disk to make the game run but managed to corrupt the sprite data.
After a year or so on AmigaOS 1.2, the release of AmigaOS 1.3 was amazing. With the advent of the FFS, we saw faster boot times, less corruption, and the whole system was a lot more stable. FFS was written in Assembler so speed jumped like 10x over the OFS. What a time to be alive. :-)
