The user data and CRC/ECC bytes transferred from the host computer are written in
the block specified by Logical Block Address by WRITE LONG command. The data
transferred from the host computer consists of user data bytes (block length) and
CRC/ECC information bytes etc.
The Byte Transfer Length specifies the total number of transfer bytes of data byte
(block length) and CRC/ECC bytes etc.
The Byte Transfer Length of 0 indicates that no data is transferred,
controller executes only seek operation to the track including the block specified by
Logical Block Address.
If the incorrect value is specified in Byte Transfer Length, the controller returns
CHECK CONDITION status with ILLEGAL REQUEST sense key.
The ILI and Valid bits of the sense data are set to 1, and the difference of the
requested length ( Byte Transfer Length ) minus the actual length ( block length +
CRC/ECC bytes etc.) in bytes is set to Information Byte.
The negative values are indicated by two's complement notation.
