I have been experiencing problems with me HD controller setup. Recently, I
ran a diagnostic software which prompted to me that my controller reported a
diffrent number of sectors per track than the diagnostic had measured. Is this
possible ? If Yes, why ? Also, I got a message that some controllers and comput
ers which employ RLL encouding "disguised" as MFM do this. What are the RLL &
MFM, and how do they work. I will apprieciate any help on this subject. :-}
