Hi Everyone,

I am starting to get seek errors on my IBM PC/XT's hard drive, and year and year and years ago, I use to go into Debug and type in:something c800:something something something.... or something like that :)

I can't remember the Debug address for low level formatting. I THINK it is a WD controller, and it is MFM for sure. (half height drive, ST-225, maybe?).

Ummm help? :D

Your entries are in boldface, the computer's in normal print.

C>DEBUG
-G=C800:5

Should do it for most WD controllers.
