 FOV (Format Option Valid): DPR, DCR, STP, IP and DSP are valid, only when set FOV to "1". Otherwise,

these bits will be set to "0", and targeter will use default value.

 DPR (Disable PList): set DPR to "1", PList will not be transferred to targeter. However, PList is provided

by device manufacturer, keep unchanged.

 STP (Stop Format): this control bit will be set when a PList or GList which is used to perform formatting

could be received by targeter while not be found or read. Command will be ended by the state of

"Check Condition" under two situations. When set STP to "1", the targeter will terminate format in

abnormal condition and gets ready for "Medium Error".

 IP (Initial Parameter), when set IP to "1", indicating parameter list contains an initial mode descriptor.

 DSP (Disable Save Parameter): in general all mode parameters will be saved during the course of format.

When set DSP to 1, this action is disabled.

 Imm (Immediately): set Imm to "1", representing state returned on receipt of parameter list. Or state

won’t be returned before task completed.

 VS (Vendor Specific): if set IP to "1", representing that parameter list header followed by an initial mode

descriptor. This mode as one byte sequence will be written to each logical block in the form of data.

 IP-MOD: these control bits allow the targeter to modify part of initial mode per logical block. 01b

represents the first four bytes per logical block should contain LBN (logical block number). 10b

represents each physical block should contain LBN. 00b represents that initial mode should be

unchanged. 11b is reserved.

 Mode Length: describes initial mode length.

 Initial Mode: mode will be written to every logical block when formatting. The mode is repeated until

the whole logical block is filled in.

The rest parameter blocks are made up of defect descriptors. Please refer to them in the following individual

section.

Defect Descriptors

Block format (000b)

The four bytes of descriptors contain LBN where the defect block locates, and the list must be set up in

ascending order when using block format. One LBN might be related to many sectors.
