from the above teachings of Jones, it is clear the when a
drive
fails, the data from the failed drive data is not regenerated
over the parity drive to form a fully folded array. In
addition,
Jones further states (col. 15, lines 56-60) that
[i]n essence, controller 100 rebuilds the data of
the failed drive into the replacement disk drive
by reconstructing the data bit by bit from the
remaining data and parity. Of course, this also
applies in the same manner when a parity disk
drive fails.
Thus, Jones will regenerate a failed parity drive onto a
replacement drive. In contrast, when appellant’s parity drive
is found to have failed, the method of reorganizing the data
terminates. We note that Jones discloses (col. 18, lines 32-
36) remapping blocks on redundant modes. However, this is in
the context of remapping correctable errors, i.e., soft
errors. we further find, as stated by the examiner, (answer,
pages 5 and 6)
that Ewert teaches remapping of bad sectors to good sectors on
the same disk, and does teach regenerating data to form a
fully folded array.
