   I have a question about intercepting the GEM dialog box that says
"The data on drive E may be damaged, Cancel or Retry".  What I would
like to to is temporarily replace this with an automatic 3-time attempt
after which it would automatically cancel and send an error to Rwabs.
Is this the critical error handler vector (etv_critic = 0x404)?  If I call
hdv_rw (0x476) and skip the call to Bios Rwabs what will happen (suppose I
should try first)?

   What is the format and return values for the critical error handler
routine?

   I am using this info to improve the read-only disc scan program scan.ttp
(free to all apon registration).
