Abstract
A data formatting system and method to improve data efficiency and integrity in a hard disk are disclosed. One embodiment provides a disk drive system having a plurality of lookup tables which store a plurality of randomizer seeds which may be dynamically encoded into the preamble field of a customer data block if the customer data is deemed marginal. Encoding the randomizer seed into the preamble field prevents adjacent data track mis-writes and mis-reads.
