FMTPINFO (Format Protection Information) field
The format protection information (FMTPINFO) field (see table 41) in combination with the PROTECTION FIELD USAGE field (see 3.3.3) specifies
whether or not the device server enables or disables the use of protection information.
When protection information is written during a FORMAT UNIT command (i.e., the FMTPINFO bit is set to one) protection information shall be
written to a default value of FFFFFFFF_FFFFFFFFh.
LONGLIST bit
If the FMTDATA bit is set to zero, the LONGLIST bit shall be ignored.
0 A LONGLIST bit set to zero specifies that the parameter list, if any, contains a short parameter list header as defined in table 39.
1 A LONGLIST bit set to one specifies that the parameter list, if any, contains a long parameter list header as defined in table 40.
FMTDATA (Format Data)
0 A format data (FMTDATA) bit set to zero specifies that no parameter list be transferred from the data-out buffer.
1 A FMTDATA bit set to one specifies that the FORMAT UNIT parameter list (see table 38) shall be transferred from the data-out buffer. The
parameter list consists of a parameter list header, followed by an optional initialization pattern descriptor, followed by an optional defect
list.
CMPLST (Complete List)
If the FMTDATA bit is set to zero, the CMPLIST bit shall be ignored.
0 A complete list (CMPLST) bit set to zero specifies that the defect list included in the FORMAT UNIT parameter list shall be used in an addi-
tion to the existing list of defects. As a result, the device server shall construct a new GLIST that contains:
a) the existing GLIST;
b) the DLIST, if it is sent by the application client; and
c) the CLIST, if certification is enabled (i.e., the device server may add any defects it detects during the format operation).
1 A CMPLST bit set to one specifies that the defect list included in the FORMAT UNIT parameter list is a complete list of defects. Any exist-
ing GLIST shall be discarded by the device server. As a result, the device server shall construct a new GLIST that contains:
a) the DLIST, if it is sent by the application client; and
b) the CLIST, if certification is enabled (i.e., the device server may add any defects it detects during the format operation).
DEFECT LIST FORMAT field
The DEFECT LIST FORMAT field specifies the format of the address descriptors in the defect list if the FMTDATA bit is set to one (see table 36).
