[comp.os.msdos.programmer] Need a critical error handler

bob@omni.com (Bob Weissman) (01/15/91)

Hi all.  I am looking for a critical error handler which behaves
as follows:

	IF
	  (error is "drive not ready") AND (drive is a fixed disk)
	THEN
	  silently do a "retry"
	ELSE
	  invoke the existing critical error handler


I need this because my combination of disk and controller gives
this particular error intermittently and retrying always succeeds.
(It's a Seagate ST-238R with a Western Digital RLL controller.  It
gets these errors only at 8 MHz, never at 4.77 MHz, by the way.)

I don't have all the documentation about device headers and other DOS
junk that I'd need to write this puppy myself, and anyway, I suspect
someone else out there has already invented this particular wheel.
Replies appreciated.

Thanks,
