A data storage system that is capable of performing a double check on data read from a storage media to determine whether the data is the data desired by a requesting host computer. If the data is not the desired data, the system discards the data before it reaches the host. The data storage system uses a randomizer unit having a variable initialization value. The initialization value is based upon the address of the data storage location being accessed by the host. If the initialization value used to read a piece of data is different than the value used to write the data, uncorrectable data errors result and the data is discarded.
