Defect List header
Field definitions (listed alphabetically)
DCRT (Disable Certification)
1
The disc drive does not perform a verify function during formatting (thus no C list for this format is created or reallo-
cated).
0
The disc drive performs a verify function during formatting and reallocates any sector that fails the verify (i.e., a C list
is created and these flaws reallocated).
On drives that have MR (magnetoresistive) heads, the DCRT bit is always interpreted as a 0 when the user sets the IP bit
(see Table 98) and specifies a format pattern of greater than 1 byte (see Table 99), and/or if the IP Modifier bits are set to 01
or 10 (see Table 99). This is done since the user format pattern and/or IP header is written onto the media during the format
certification phase. Because of this the user may see G list entries added to the defect list even though the DCRT bit was
set to 1.
Defect List Length
The length of any following D list (Defect descriptors) must be equal to 8 times the number of sectors to be reallocated per
Table 102 or Table 103.
Note.
The initiator may not use any previously defined C, G, or D lists if the sector size (block length) has been changed.
DPRY (Disable Primary)
1
Flaws in the disc drive P list are not reallocated during formatting. This means existing reallocations of the P list are
canceled and no new reallocations made during formatting. The P list is retained.
0
Flaws in the disc drive P list are reallocated during formatting. A Check Condition is sent in the status if the P list
cannot be found by the disc drive.
DSP (Disable Saving Parameters)
1
The target does not save the Mode Select savable parameters to nonvolatile memory during the format operation.
0
The target saves all the Mode Select savable parameters for all initiators to nonvolatile memory during the format
operation.
FOV (Format Options Valid)
1
The disc drive interprets the remaining bits of byte 1.
0
The disc drive checks the remaining bits of byte 1 for zeros.
