Recommendations for disk repair utilities?

[avadondragon]

I'm curious what people think is the best tool for hard drive diagnostics / repair under classic Mac OS.  Specifically on 68k macs but PPC input welcome as well.  Hard drive errors are a common issue with these aging machines and it seems like having a list handy would be a useful resource.  I'm sure there are plenty of tools I'm unaware of.

Norton Disk Doctor

DiskWarrior

About the only two that do anything and work well

Seconding Norton Disk Doctor.  About the only annoying thing is that is thinks a bad file creation date (like for instance, when you don't have a clock battery and don't care about setting the correct time) is a major problem that needs to be corrected.
