The ONLY programs worth using to analyze / repair / optimize AMIGA hard drives are either DiskSalv 4 (Dave Haynie) or Quarterback Tools Deluxe (don't recall the version numer ATM but it came out in late 1994).
NOTE - THESE PROGRAMS ONLY WORK WITH OS3.1 and earlier! They are not for use with OS3.9 (OS3.5?) due to the change in drive parameters and updated FFS (working with drives greater then 4GB). If you are using OS3.9, look for a similar program on Aminet, etc...
I have used both programs and they essentially do the same thing (although QBD also lets you back up your AMIGA). Which one is better is a matter of preference.
