This option is obsolete and will be removed in future versions.
--csmiUsePort (Obsolete)
This option is obsolete and will be removed in future versions.
--csmiVerbose (Obsolete)
This option is obsolete and will be removed in future versions.
--echoCommandLine
Echo the command line entered into the utility on the screen.
--enableLegacyUSBPassthrough
Only use this option on old USB or IEEE1394 (Firewire) products that do not otherwise work with
the tool. This option will enable a trial and error method that attempts sending various ATA
Identify commands through vendor specific means. Because of this, certain products that may
respond in unintended ways since they may interpret these commands differently than the bridge
chip the command was designed for.
--forceATA
Using this option will force the current drive to be treated as a ATA drive. Only ATA commands
will be used to talk to the drive.
--forceATADMA
(SATA Only)
Using this option will force the tool to issue SAT commands to ATA device using the protocol set
to DMA whenever possible (on DMA commands). This option can be combined with --forceATA
--forceATAPIO
(SATA Only)
Using this option will force the tool to issue PIO commands to ATA device when possible. This
option can be combined with --forceATA
--forceATAUDMA
(SATA Only)
Using this option will force the tool to issue SAT commands to ATA device using the protocol set
to UDMA whenever possible (on DMA commands). This option can be combined with --forceATA
--forceSCSI
Using this option will force the current drive to be treated as a SCSI drive. Only SCSI commands
will be used to talk to the drive.

Utility Arguments =================
-d, --device [deviceHandle | all]
Use this option with most commands to specify the device handle on which to perform an operation.
Example: /dev/sg<#> CSMI device handles can be specified as <error<#><#><#>> To run across all
devices detected in the system, use the "all" argument instead of a device handle. Example: -d
all NOTE: The "all" argument is handled by running the
specified options on each drive detected in the
OS sequentially. For parallel operations, please use a script opening a separate instance for each
device handle.
-F, --scanFlags [option list]
Use this option to control the output from scan with the options listed below. Multiple options
can be combined.
ata - show only ATA (SATA) devices
usb - show only USB devices scsi - show only SCSI (SAS) devices nvme - show only NVMe devices
interfaceATA - show devices on an ATA interface interfaceUSB - show devices on a USB interface
interfaceSCSI - show devices on a SCSI or SAS interface interfaceNVME = show devices on an NVMe
interface sd - show sd device handles sgtosd - show the sd and sg device handle mapping ignoreCSMI
- do not scan for any CSMI devices allowDuplicates - allow drives with both CSMI and PD handles
to show up multiple times in the list
-i, --deviceInfo
Show information and features for the storage device
-s, --scan
Scan the system and list all storage devices with logical /dev/sg<#> assignments. Shows model,
serial and firmware numbers. If your device is not listed on a scan immediately after booting,
then wait 10 seconds and run it again.
-S, --Scan
This option is the same as --scan or -s, however it will also perform a low level rescan to pick
up other devices. This low level rescan may wake devices from low power states and may cause the
OS to re-enumerate them. Use this option when a device is plugged in and not discovered in a
normal scan. NOTE: A low-level rescan may not be available on all interfaces or all OSs. The
low-level rescan is not guaranteed to find additional devices in the system when the device is
unable to come to a ready state.
--SATInfo
Displays SATA device information on any interface using both SCSI Inquiry / VPD / Log reported
data (translated according to SAT) and the ATA Identify / Log reported data.
--testUnitReady
Issues a SCSI Test Unit Ready command and displays the status. If the drive is not ready, the
sense key, asc, ascq, and fru will be displayed and a human readable translation from the SPC spec
will be displayed if one is available.
--fastDiscovery
Use this option
to issue a fast scan on the specified drive.
--errorLimit [limit in number of LBAs]
Use this option to specify a different error limit for a user generic or long generic read test or
DST and Clean. This must be a number of
logical LBAs to have errors. If a drive has multiple logical sectors per physical sector, this
number will
be adjusted for you to reflect the drive architecture.
--checkGrownListCount [count to check]
Use this option to check if the grown defect list count is greater than the provided value.
--checkPendingListCount [count to check]
Use this option to check if the pending defect list count is greater than the provided value.
NOTE: This only works on SAS products that support the Pending Defects log page from SBC4 or later
--showPendingList
Use this option to show the pending defect list as it is reported by the drive. NOTE: SBC4
pending log required for SAS support.
SAS Only:
--defectFormat [ # | shortBlock | longBlock | xbfi | xchs | bfi | chs ] (SAS Only)
This option set the format of the defects to output. Not all drives will support all defect
modes! SSDs will only support block modes! Arguments: (name | #)
shortBlock | 0 - show the defects in short block address mode (drives < 32bit LBA) xbfi | 1
- show the defects in extended bytes from index mode xchs | 2 - show the defects in extended
physical cylinder-head-sector mode longBlock | 3 - show the defects in long block address mode
(drives > 32bit LBA) bfi | 4 - show the defects in bytes from index mode chs | 5 -
show the defects in physical cylinder-head-sector mode
--showSCSIDefects [ p | g | pg ]
(SAS Only)
This option will display the SCSI defects on the screen. The arguments to this will tell whether
to get the grown, primary, or primary and grown defects from the drive. Use the --defectFormat
option to specify the mode to display the defects. If no mode is specified, physical
cylinder-head-sector mode is assumed Arguments:
p - use this option to pull and display the primary (factory) defects g - use this option to pull
and display the grown (reallocated) defects
The above options can be combined to pull and display both defect lists.
Data Destructive Commands =========================
--bytesToCorrupt [# of bytes]
Use this option to specify the number of data bytes to change when used with the --corruptLBA
option.
--dstAndClean
Runs DST, then checks for an error and repairs the error if possible. This continues until all
errors reported by DST are fixed, or when the error limit is reached. The default limit is 50
errors.
--corruptLBA [lba]
Use this option to corrupt the data bytes of an LBA. The --bytesToCorrupt option can be used to
specify the number of bytes to corrupt. If that option is not given, a default will be used that
attempts to create a correctable error on the drive. This option can be used to create
uncorrectable or correctable errors on a drive, depending on it's ECC algorithm and the number of
corrupted data bytes.
--corruptRandomLBAs [# of LBAs to corrupt]
This option will corrupt the specified number of LBAs randomly on the device. The --bytesToCorrupt
option can be used to specify the number of bytes to corrupt. If that option is not given, a
default will be used that attempts to create a correctable error on the drive. This option can be
used to create uncorrectable or correctable errors on a drive, depending on it's ECC algorithm and
the number of corrupted data bytes.
--corruptRange [# of LBAs]
This option is used with the --corruptLBA option to corrupt a range of LBAs on the drive.
--disableReadUncorrectables
Use this option to disable issuing read commands to the LBAs where errors are written. This option
should only be used for debugging. When this option is used, the uncorrectable errors may not end
up being logged in the Pending Defect List on the drive.
--flaggedUncorrectable
Use this option to flag an uncorrectable error instead of creating a pseudo uncorrectable error
with the --psuedoUncorrectable or --randomUncorrectables options. Error types:
Pseudo - creates a pseudo uncorrectable error. The device
will perform full error recovery and logging on failure.
Flagged - flags an error. The device will not perform error
recovery and will not log on failure.
--psuedoUncorrectable [lba]
Use this option to create a uncorrectable error at the specified LBA. Use --uncorrectableRange to
specify a range. By default, pseudo uncorrectable errors will be created for the entire physical
sector. Use the --flaggedUncorrectable option to flag errors instead. Flagged errors do not get
logged or have any error processing when encountered.
--randomUncorrectables [number of errors]
Use this option to create a number of random uncorrectable LBAs on a drive.
--uncorrectableRange [range]
Use this option to specify a range of LBAs to create an uncorrectable error at. This option must
be used with the --psuedoUncorrectable or --flaggedUncorrectable options so that a starting LBA is
specified.
