Output Parameters To The Device

It should be noted that the device internally uses 40 bytes of ECC data on all data written or read from the

disk. The 4-byte mode of operation is provided via an emulation. For testing the effectiveness and

integrity of the ECC functions of the devide it is recommended that the 40-byte ECC mode should be

used.
