Application No. 08/084,370
The examiner asserts (answer, page 4) that in Jones, the
requirement for a spare disk is a direct result of the fact
that the defective sectors have exceeded the storage capacity
of a particular drive unit. In the examiner’s opinion (id.),
this teaching of Jones, along with Jones’ teaching of
replacing the disk in order to continue complete data
guarding,
would strongly suggest that there is another course
of events which are available to sector remapping.
It is the Examiner's position that the other
possible event is the choice of remapping without
data guarding, that
is, to remap the defective sectors onto the same
disk until the capacity of the disk is fully
utilized, as cited above in Jones. While the
Examiner realizes that this is not an explicitly
[sic] suggestion for over-writing parity data, it is
a strong suggestion that data on a disk maybe [sic]
over-written, and as acknowledged by Appellant, the
disk in this invention contains both parity and raw
data. Therefore, it would seem logical that the
data being over-written maybe [sic] either old
undesirable data or the guarded data (parity data)
which is being sacrificed in order to retain
desirable data.
and that (answer, page 5)
[a]cknowledging, that Jones' invention is primarily
concern [sic] with retaining with a high degree, the
reliability or guarding (redundancy) of data in the
system. This does not mean that he is oblivious to
