The IDE controller problem with corrupting data was for rev. 1 (A) B&W's. They were all 300 MHz models and some earlier 350 MHz models.
Do you now have all pertinent documents off the bad drive? And what happens when Norton's tries to repair the drive? Does it just hang (freeze) your computer? Oh yeah, and what version of Norton's are you using? Usually if it is a corrupt directory Norton's can repair that and usually when it hangs trying to repair a drive it means that there and bad blocks appearing (bad blocks will probably mean the end of that hard drives life).
Try and give Norton's as much allocated memory as possible, I found out that some tasks will hang the computer if not enough memory is alloted to Norton's Disk Doctor and after alloting more memory the task went through. Oops, not sure if your trying this from a CD.
If all pertinent documents are safely backed up somewhere else and you have all the installers for your applications. Try and see if Apple's Drive Set up can recognize the drive, if so, then you are at least able to initialize (reformat) it and see if it is indeed a corrupt directory. If you go through with initializing the drive, you will infact lose all data on that drive, why I asked if you already have everything backed up.
