SMDTEST displays and logs error messages with the for-
mat described in the INTRODUCTION TO SMD DIAGNOSTICS.
The

Explanation
The diagnostic was writing
a single sector in test 1.
The diagnostic was reading
a single sector in test 1.
The diagnostic was writing
a random-length buffer in
t est 2. Th e 1 eng t h in by t es
replaces "xxxx" (hexadecimal).
The diagnostic was reading

SMDTEST will also display the following messages:
CMP ERR IN BUFFERS: SRC<ss>soff=sd DST<ds>doff=dd
ORIG BUFS: WR<ws>woff RD<rd>roff L=llll DISK:u,cccc,hh,ss
A mismatch was found comparing the buffer written
to the buffer read. The addresses and data where
the data mismatch occurred are given by SRC and
DST. The address and data in the write buffer
where the mismatch occurred replace "ssft (segment,
decimal), "soff" (offset, hex) and "sd" (data,
hex). The address and data in the read buffer
where the mismatch was found replace "ds" (seg-
ment, decimal), "doff" (offset, hex) and "dd"
(data, hex). Similarly, the beginning addresses
of the write and read buffers are given by' the
values following WR and RD. The buffer length in
bytes replaces "1111" (hexadecimal).
