A combination of 2, 3, and 4 may have
occu~~ed.
It
is
necessary
to
be knowledgeable of the MOOS file
structure before allocation conflicts can be
~isely
~esolved.
It
should
be

that
although space is allocated to a

IT
onl~
an Outer rile is displayed with no
Inner
Tiles
at
the
beginning
of
Phase
4, then
the user
has locked out
sectors which conflict with files that
al~eady
have allocated
space.
REPAIR
assumed
that
the
correct
sectors
were
specified
by
the user during the Phase
1;
howeverl
if
that is
not
true,
then
this
kind of a allocation conflict will be
seen.
22.6 CAT Replacement Phase
Phase 5 of the REPAIR command compares the reconstructed
allocation
table
in memory with the actual allocation table
on the diskette.
If the two
tables
are
identical
(normal
case),
REPAIR will display the message
RECONSTRUCTED
C.A. T. MATCHES DISK
before terminating and returning
cont~ol
to MDOS.
If
the
reconst~ucted
table
does not match the one on
diskette,
and
if no
RIB
errors remain,
then the message
WRITE
RECONSTRUCTED
C. A. T. TO DISK?
will be displayed.
The operator must respond
~ith
either
a
"Y"
or
an
"N
u
.
The
llyn
response
ud11
cause
the
new
allocation table (the correct
one)
to
be
written
to
the
diskette.
The
"NII
response will leave the erroneous system
table intact.
MOOS
~il1
be
given
control
after
either
response.
The
allocation table that is written to the diskette is'
a combination of Table 1 which was built
during
Pass
1
of
Phase
4,
and
the
LCAT.
If
Tiles with invalid RIBs
were
encountered during the REPAIR process which were'not deleted,
in all probability the allocation tables will differ.
REPAIR
will not update the
diskette
table
until
the
riles
~ith
invalid
RIBs
are
fixed
or
deleted
(but
they
must
not be
deleted with the DEL command -- only by the REPAIR
command).
In
such cases,
REPAIR will display the message
INVALID RIES RESULTED IN RECONSTRUCTED C. A. T.
NOT MATCHING
DISK
as a reminder that the allocation table and some RIBs contain
e~rors.
MDOS
is
given
