Field Default Description
PS 1 Parameters Savable. This bit is only used with the MODE SENSE
command. A returned value of 1 indicates that the disk drive is
capable of saving the page in a non-volatile, vendor-specific
location. The bit is RESERVED with a MODE SELECT command.
Wait SpinUp Enable 0 When this field = 0, the disk drive spins up upon power on.
When this field = 1, the disk drive performs a Wait/Spin.
Enable Error Logging 0 When this field = 0, Error Logging is disabled.
When this field = 1, Error Logging is enabled.
Disable Parity Check 0 When this field = 0, Parity Checking is enabled.
When this field = 1, Parity Checking is disabled.
Reall. Uncorr. Errors 0 When this field = 0, reallocation of blocks that have
uncorrectable READ errors does not take place. (Note that if this
field is set to 0 and ARRE bit in Page 01 of the Error Recovery
Parameters is set to 1, no reallocation takes place.)
When this field = 1, and ARRE bit in Page 01 of the Error
Recovery Parameters is set to 1, the disk reallocates a block that
has an uncorrectable READ error the next time this block is
written (the default for ARRE is 1).
Enable Fill Data Pattern 1 When this field = 0, the disk drive ignores any information in
Byte 2 of the FORMAT UNIT command. Note that if the setting
in Byte 2 of FORMAT UNIT is “0”, the disk drive will interpret
that setting as “1.”
When this field = 1, the disk drive writes the data pattern that is
specified in Byte 2 of the FORMAT UNIT command into every
user-accessible block when the disk drive executes a FORMAT
UNIT command.
Disable SCAM 1 (Parallel) When this field = 0, SCAM is enabled. When this field = 1,
SCAM features are disabled.
Disable Unit Att’n 0 When this field = 0, a UNIT ATTENTION condition exists
following power on or a reset caused by either a BUS DEVICE
RESET message or a hard reset condition.
When this field = 1, the disk drive will not issue a CHECK
CONDITION status with the UNIT ATTENTION sense key on the
first command following a reset. The disk drive will execute the
first command issued after a reset condition.
Disable IWR 0 Disable Wide Residue Message. When this field = 0, the disk
drive sends the IGNORE WIDE RESIDUE message.
When this field = 1, the disk drive will not send the IGNORE
WIDE RESIDUE message.
