Comment(by Quozl):

 Thanks.

 I was able to use the image to prepare a USB drive and test it with
 Q4D04jd.  The test was to read the file from start to end, to see if I
 could induce an error.  The test worked without error.

 This excludes partitioning and filesystem format as the cause, leaving
 only a hardware problem that OpenFirmware does not recover from.

 However, there is another slim possibility.  If the system you used to
 create the zeroes file (A) is different to the system you use to copy .zd
 files (B), then please do the folllowing using that system (B):
  * copy the zeroes file from the USB drive to the system,
  * delete the file from the USB drive,
  * copy the zeroes file to the USB drive from the system,
 Then provide the image again.

 Modified test script:
 {{{
 h# 100000 value /buf
 0 value handle
 : raf ( "file" -- )  \ read a file
   safe-parse-word
   $open-canonical-file to handle  /buf alloc-mem >r
   " size" handle $call-method drop                      ( input-file-size
 )
   dup ." size = 0x" . cr                                ( input-file-size
 )
   begin  ?dup  while                                    ( #remaining )
      r@  /buf " read" handle $call-method               ( #remaining #read
 )
      dup /buf = if  [char] .  else  [char] :  then emit ( #remaining #read
 )
      -                                                  ( #remaining' )
   repeat
   cr  r> /buf free-mem  handle close-dev
 ;
 }}}

 Observed output:
 {{{
 ok raf u:\zeroes
 size = 0x3d6e9000
 ......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................:
