Tape Copy Procedure
CAUTION
You can use this procedure
to
copy individual files,
except 8,
9,
and 15, from the
CE
diagnostic cartridge.
If
files
8,
9, and 15 are copied,
MDls
860 and
891
tests
(average velocity and peak shift head azimuth) might be
inaccurate.
To copy
an
entire tape, use the tape copy program on
the customer support cartridge. The tape copy program
is called via the PATCH program using )PATCH (APL)
or
PATCH (BASIC). .
To repair individual files on a
CE
diagnostic tape, use
the following procedures:
1.
Use the C CMD 8 function
to
store the desired file
in
read/write
storage at location 0800.
2.
Insert the tape cartridge
to
be
repaired.
3.
Enter C
CMD
9.
4.
Enter the beginning storage location (0800) and
the end storage location
(FFFF).
Note: Error E80 010 is a normal ending error.
5.
Enter the tape file number in hex that was loaded
from the good tape
(0001
-001
F),
and the file type
number (0011
J.
6.
Enter the storage selection (0000).
7.
Press EXECUTE. The sequence
of
C CM D 8 and
C CMD 9
can
be repeated
for
each
of
the files on
the
CE
diagnostic cartridge.
8.
Return
to
DCP1
diagnostic mode by pressing
ATTN.
9.
Exit from
DCP1
diagnostic mode, after copying the
tape, by pressing RESTART.
10.
Insert the repaired tape cartridge and verify
that
it
is fixed.
To copy individual files from storage
to
tape, use the
following procedure:
1.
The file
to
be copied from storage must have been
previously loaded using the CMD 8 function; or
it
must already
be
in the storage locations you
specify.
2.
Press
and hold the CMD
k~y.
3.
If
you are already in
DCP1
diagnostic mode, go
to
step

to
a tape).

15. Press the EXECUTE key.
The file that was
in
the storage positions specified
in
steps 10 and
11
has
now
been loaded on the tape
in
the file number specified in step 12. This procedure, in
conjunction
with
CMD 8 function, allows you
to
load
files into storage
from
one tape and then dump them
onto another tape.
It
is also useful in checking
suspected files that may contain CRe errors. By loading
the file into storage (using CMD
8),
the
CRC
and data is
verified
for
parity.
