READ (10) LONG (3Eh)

The READ (10) LONG (3Eh) command is used for ECC (Error Correcting Code) data that was written

using the WRITE LONG command. The CORRECT bit is ignored and is always assumed to be set

to 1. If an ECC error is detected, the data is ECC corrected if possible before being returned. The

BYTE TRANSFER LENGTH must be set to 0x218 (536 bytes).

Table 34. Read (10) Long (3Eh) CDB

RITE (10) LONG (3Fh)

The WRITE (10) LONG (3Fh) command is complementary to READ (10) LONG (3Eh). It allows for

ECC (Error Correcting Code). The data sent by the initiator will include ECC fields with the data. The

Byte Transfer Length field informs the target device the amount of data that is expected to be returned

when the READ LONG command is used.
