What does (can) one do about bad Mac disks?

One particular disk always gets the message "This is not a Macintosh
disk" (not "unreadable"), and when I OK initialization, the Mac does
a litlle something and then spits it out with the message
"Initialization failed." 

Is this a hardware failure, tracking failure, or what?  I'm not hard
up for the disk, but I'd like to salvage it if possible.
(I think I may have tried to initialize it for the first time with a
system that I had been tinkering with - might this have done
something to the disk?)

Thanks for any help (or condolence).

I tended to experience this effect semi randomly.  It was always
in the external drive.  It stopped when I moved the drive to sit
on the right side of Mac rather than on the top.  Mag fields?

	Other people have experienced field related problems with the Mac.  Sit
your drive on the right or left side.  Having it on top is a bad idea
anyway, as it inhibits airflow and causes overheating.  Without a fan this
is serious.
