Ok, I downloaded the new C1571.COM from Compuserve and, sure enough, it now
behaves well, and works as advertised.

This still leaves me with two questions:

1. I downloaded my original, buggy copy of C1571.COM from the public domain CP/M
   repository at White Sands Missile Range.  As I understand it, this new copy
   I got from Compuserve is copyrighted by Compuserve, and is not public domain.
   Is this true, or is permission from Commodore sufficient to distribute it to
   others and/or to send it to Mr. Wancho to update the bad version in the CP/M
   repository?

2. If C1571.COM is executed without options, it prints a screen of instructions
   which specifically state that a verification after write is disabled, but
   it has been stated in this forum that the speedup is attained by *eliminating
   retry after error* processing.  These are quite different things.  It would
   seem quite an unsafe practice to write to a disk sector with *no* check
   whatever to ensure that the sector was written correctly.  On the other hand,
   I would not expect *retry after error* processing to have any substantial
   effect on write speed, since typically there are no errors.  So is this
   program safe to use, or not?

Sincerely,
