Description
DSP
The Disable Saving Parameter prohibits the drive from preserving MODE
SELECT parameters received while the Format is in progress. This bit is
ignored, and the drive acts as if it were set.
Immed
When the Immediate bit is 0, the drive returns a status after the format
operation completes. If the disconnect privilege is granted in the
accompanying IDENTIFY message, the drive disconnects from the bus after
fetching and validating the Command Descriptor Block and the FORMAT
UNIT Parameter List. If the disconnect privilege is not granted, the drive stays
connected to the bus during the entire FORMAT UNIT command.
When the Immediate bit is set to 1, the drive returns a status after the
Command Descriptor Block and FORMAT UNIT Parameter List have been
fetched and validated. In this case, the drive ignores the IDENTIFY message's
disconnect privilege bit and remains connected to the bus while it validates
the Command Descriptor Block and Parameter List. It returns the completion
status before it disconnects. The drive then proceeds with the format.
VS
Vendor-specific. Must be 0.
Defect List Length
Gives the length in bytes of the Defect Descriptors that follow. A value of 0 is
valid and means that no Defect Descriptors follow. A CHECK CONDITION
status is returned if this value is not a multiple of the defect descriptor size.
The Defect List Length is equal to four times the number of defect descriptors
if Block format is used, or eight times if Bytes From Index format or Physical
Sector format is used.
5.10.2.2 FORMAT UNIT Defect Descriptor — Block Format
Each descriptor specifies a 4-byte defective sector address of the sector that contains
the defect.
