was not sent, so no additional status information

is available.

by OutDataBuffer.

|
@retval EFI_NOT_READY The ATA command could not be sent because there

are too many ATA commands already queued. The
|

caller may retry again later.

@retval EFI_DEVICE_ERROR A device error occurred while attempting to

send the ATA command.
