Quick Help:
Format Partition, m[Partition],[FormatOpts],[DefectListOpts],[MaxWrRetryCnt],[MaxRdRetryCnt],[MaxEccTLevel],[MaxCertifyTrkRewrites],[ValidKey],[DataPattern]
Description:
This command formats the specified partition.
Input Parameters:
0 - Partition Number.
This parameter specifies the media partition to be formatted.
0 = User Partition
1 = System Partition
99 = Set format corrupt state
Type: Unsigned 8-bit value
Range: 0 or 1
Default: 0
1 - Format Options.
This parameter is a bit significant value that selects the following options:
Bits 31-5: not used
Bit 6: Disable Track Re-write for Data Sync Time-out Errors.
If this bit is equal to 1, the the Format Partition command will
not perform track re-write operations for an unrecovered
data sync time-out error.
NOTE: This feature can be enabled or disabled at compile-time. Use
the quick help to determine whether your code supports this feature.
Bit 5: Enable SeaCOS XF Space Format.
This bit is only valid when the User Partition is selected. If this
bit is equal to 1, the the Format Partition command will only format
SeaCOS Extended File (XF) space.
NOTE: This feature can be enabled or disabled at compile-time. Use
the quick help to determine whether your code supports this feature.
Bit 4: Enable Zone Re-format Skipping.
If this bit is equal to 1, then the Format Partition command will
enable the zone re-format skipping mode during the format operation.
With this mode enabled, the format operation will not re-format
a zone if grown defects were found in the zone.
NOTE: This feature can be enabled or disabled at compile-time. Use
the quick help to determine whether your code supports this feature.
Bit 3: Enable Event-based Format Logging.
If this bit is equal to 1, then the Format Partition command will
display information about error events that occur during the format
operation. This information will be displayed as interim status as
these events occur.
NOTE: This feature can be enabled or disabled at compile-time. Use
the quick help to determine whether your code supports this feature.
Bit 2: Disable User Partition Certify.
This bit is only valid when the User Partition is selected. If this
bit is equal to 1, media certification and defect deallocation will
be disabled.
Bit 1: Disable User Partition Format.
This bit is only valid when the User Partition is selected. If this
bit is equal to 1, the User Partition sectors will not be written
with a constant data pattern.
Bit 0: Corrupt User Partition Primary Defects.
This bit is only valid when the User Partition is selected. If this
bit is equal to 1, the primary defective sectors will be corrupted.
Type: Unsigned 32-bit value
Range: 0 or 0xFFFFFFFF
Default: 0 (Enable User partition Certify,
Enable User Partition Format,
Don't Corrupt Primary Defects)
2 - Defect List Options.
This parameter is a bit significant value that selects the following options:
Bits 31-3: not used
Bit 2: Process the Active Error Log.
This bit is only valid when the User Partition is selected. If this
bit is equal to 1, the Format Client Defect List will be written with
contents of the Active Error Log and the option to process the Client
Defect List will be enabled. If there is no Active Error Log or there
are no R/W-related entries in the Active Error Log, then this bit will
be ignored.
Bit 1: Process Primary Defect Lists.
This bit is only valid when the User Partition is selected. If this
bit is equal to 1, the the Primary Defect Lists will be used when
creating the defect list to be used by the format operation.
Bit 0: Process Grown Defect Lists.
This bit is only valid when the User Partition is selected. If this
bit is equal to 1, the the Grown Defect Lists will be used when
creating the defect list to be used by the format operation.
Type: Unsigned 32-bit value
Range: 0 or 0xFFFFFFFF
Default: 0x00000003 (Process Grown Defect Lists,
Process Primary Defect Lists,
Do not process the Active Error Log)

Default: None.
5 - Max iteration count
If this paremeter is entered, the iteration count will be set to the specified
value. This parameter is only valid when the User Partition is being formatted
(Parameter 0 is equal to 0). If this parameter is not entered, the iteration
count will not be changed.
5 - Maximum ECC T-Level.
If this paremeter is entered, the maximum ECC T-Level will be set to the specified

Examples:
Example #1:
Perform a "quick format" (process defect lists, clear format corrupt, do not write
or certify the drive)
F3 T>m0,6,,,,,,22
Example #2:
Perform a "quick format" (don't process defect lists i.e. unslip and unalt, do not
write or certify the drive)
F3 T>m0,6,0,,,,,22
Example #3:
Perform a format with the default data pattern 0x00000000 and certify with event
reporting enabled:
F3 T>m0,8,,,,,,22
Example #4:
Perform a format and certify with event reporting enabled, set max write retries
to 16, set max read retry count to 8, max ECC T-Level to 0, and track rewrite
during certify retry threshold to 20:
F3 T>m0,8,,10,8,0,14,22
Example #5:
Perform a format with user input data pattern 0xFFFFFFFF and certify with event
reporting enabled:
F3 T>m0,8,,,,,,22,ffffffff
Example #6:
Perform a format with secondary ER mode feature. Two sets of ER mode parameters are
entered. First set is used in the first pass of format/certify, set max write retry
to 15, max read retry to 5 and max ECC T-Level to 6. Second set is used in the rest
passes, set max write retry to 17, max read retry to 7 and max ECC T-Level to 14.

list processing error occurred.
0012.03XX Added support for skipping track re-write operation on data sync time-out errors.

0012.05XX Corrected output for iterative channels
Note on Minor Rev:
----.ZZXX ZZ represents the minor rev base value.
XX represents set of conditional feature supported by the command.
- If bit 0 of X is set, then the ability to enable and display
event-based output is supported.
- If bit 1 of X is set, then the ability to enable zone re-format
skipping and output command result information if at least one
zone re-format was skipped is supported.
- If bit 2 of X is set, then the ability to format only SeaCOS
Extended File (XF) space is supported.
- If bit 3 of X is set, then the ability to use secondary ER mode
to format/certify is supported.
- If bit 4 of X is set, then the command supports brief event
reporting.
- If bit 5 of X is set, then the command supports skipping of
