TEST UNIT READY COMMAND (00h)

The TEST UNIT READY command provides a method to check if the logical unit is ready. This is

not a request for a self-test. If the logical unit would accept an appropriate medium-access command

without returning CHECK CONDITION status, this command shall return a GOOD status. If the

logical unit cannot become operational or is in a state such that an initiator action is required to make

the unit ready, the target shall return CHECK CONDITION status with a sense key of NOT READY.

Byte 5 is ignored..

ORMAT UNIT (04h)

The FORMAT UNIT (04h) command will request that the device server format the medium into

application client-accessible logical blocks as specified in the number of blocks and block length

values received in the last mode parameter block descriptor in a MODE SELECT command. The

device server may certify the medium and create control structures for medium management and

defects. The degree to which the medium is altered is vendor-specific.
