The CURRENT AMOUNT OF DATA WRITTEN field indicates the amount of data physically written to the medium during this load of the medium. This value is expressed in increments of 1048576 bytes (e.g., a Value of one means 1048576 bytes, two means 2097152 bytes, etc).
The CURRENT WRITE RETRY COUNT field indicates the total number of write retry was performed during this load of the medium. The exact definition of the error counters is not part of this standard. This counter should not be used to compare products because the products may define errors differently.
