In going through my pile of hard drives I've found one that
breaches IDE protocol, in that if you attempt to read past the end
of the disk it hangs instead of giving a "sector not found" error.
This may the the problem you experienced here. I'm going to add
another option to HDInit to allow the user to explicity specify
the drive size instead of investigating the drive for it.
