The ReceiveData function sends a security protocol command to the given MediaId.
|

The security protocol command sent is defined by SecurityProtocolId and contains

the security protocol specific data SecurityProtocolSpecificData. The function
|
|
returns the data from the security protocol command in PayloadBuffer.
|
|
|
|
For devices supporting the SCSI command set, the security protocol command is sent
|
|
using the SECURITY PROTOCOL IN command defined in SPC-4.
|
|

|
For devices supporting the ATA command set, the security protocol command is sent
|
|
using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize

is non-zero.
|
|
|
|
If the PayloadBufferSize is zero, the security protocol command is sent using the
|
|
Trusted Non-Data command defined in ATA8-ACS.

of the security protocol command. A Timeout value of 0

security protocol command to execute. If Timeout is greater
