storage is initialized, the data restored and written in the

operations is read from the spare disk storage 3, and the read
data is copied to the disk storage which has been initialized’”
(see page 7 of the answer).
However, we have reviewed Ohizumi, especially column 4,
lines 12-18, thereof, and we agree with appellants that there is
no teaching of rebuilding data units, as claimed, in Ohizumi.
Rather, Ohizumi appears to teach copying data read from a spare

in Ohizumi as far as we can tell, suggesting rebuilding data
