Claim 0:
1. A storage system comprising:
a NAND storage device comprising a plurality of blocks of storage; and
a controller coupled to the NAND storage device and programmed to:
(a) identify one or more partially written blocks of the plurality of blocks of storage for which a written percentage of each block of the one or more partially written blocks is below a threshold percentage for each block of the one or more partially written blocks, the threshold percentage being a function of a number of program and erase cycles of each block of the one or more partially written blocks and being selected such that failed bit counts remain correctable according to error correction implemented by the NAND storage device; and
(b) in response to the written percentage of each block of the one or more partially written blocks being below threshold, write one or more lines of dummy data to a layer following a last-written line of each block.
