I'll bet that the disk was formatted using Diversi-DOS, an early Shareware
project for an accellerated DOS 3.3 which also had some additional
features.  I don't remember what those additional features were, but I do
remember that in order to make room for those features, the author
sacrificed the error message table.

The bad news:  Error #8 under DOS 3.3 or its clones (actually, I think
it's the same under ProDOS) is:  I/O ERROR.

Here are the DOS 3.3 (/Diversi-DOS/David-DOS/Pronto-DOS/etc) error codes
as published in THE DOS MANUAL (Apple P/N 030-0115-B):

    1     LANGUAGE NOT AVAILABLE
    2     RANGE ERROR
    3     RANGE ERROR
    4     WRITE PROTECTED
    5     END OF DATA
    6     FILE NOT FOUND
    7     VOLUME MISMATCH
    8     I/O ERROR
    9     DISK FULL
   10     FILE LOCKED
   11     SYNTAX ERROR
   12     NO BUFFERS AVAILABLE
   13     FILE TYPE MISMATCH
   14     PROGRAM TOO LARGE
   15     NOT DIRECT COMMAND

While I am at it, here are the Applesoft ?error codes:
    0     ?NEXT WITHOUT FOR
   16     ?SYNTAX ERROR
   22     ?RETURN WITHOUT GOSUB
   42     ?OUT OF DATA
   53     ?ILLEGAL QUANTITY ERROR
   69     ?OVERFLOW ERROR
   77     ?OUT OF MEMORY
   90     ?UNDEF'D STATEMENT
  107     ?BAD SUBSCRIPT
  120     ?REDIM'D ARRAY
  133     ?DIV BY 0 ERROR
  163     ?TYPE MISMATCH ERROR
  176     ?STRING TOO LONG
  191     ?FORMULA TOO COMPLEX
  224     ?UNDEF'D FUNCTION
  254     ?REENTER
  255     BREAK

I don't have the Integer BASIC ***ERR codes handy...  8-)

ProDOS's BASIC.SYSTEM uses a superset of the DOS 3.3 error codes, and
error 8 is I/O ERROR.

The ProDOS kernel and device drivers use a completely different error
numbering system, and applications other than BASIC.SYSTEM may report
the ProDOS error code directly.  (I/O error is $27 for ProDOS.)
