This command reads the logical data block data and its ECC byte, specified in the “Logical
block address” field in the CDB, from the disk media and transfers it to the INIT. Normally,
this command is used in combination with the WRITE LONG command to perform checks of
the ECC function. The operation object in this command is 1 data block only.
Remark
The Pad Byte and Sync Byte patterns are not included in the transfer data.
