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

--dcoFreezeLock (SATA Only)

    Use this option to issue the DCO freeze-lock command. Issuing this command will prevent the ability to modify available capabilities or restore default capabilities until the device has been power cycled.

--dcoIdentify
    (SATA Only)

    This option will list the capabilities that can be restricted with DCO. Restricted capabilities are MWDMA and UDMA transfer modes, maximum LBA, and some ATA features or commands. This will not work if the device has been DCO frozen. NOTE: Some motherboards will issue a DCO freezelock when booted.

If DCO is frozen each time the system is rebooted, try a
    different system or add-in card to work around this.

--dcoRestore
    (SATA Only)

    Use this option to restore device capabilities and features hidden by DCO back to factory defaults. This can only be used if DCO is not frozen and HPA has not been used to reduce the maximum LBA already. Recommend restoring the max LBA prior to this option for best results. NOTE: Some motherboards will issue a DCO freezelock when booted.

If DCO is frozen each time the system is rebooted, try a
    different system or add-in card to work around this.

--dcoSetMaxLBA [new max LBA]
    (SATA Only)

    Use this option to set a lower max/native max LBA using the DCO feature. This should be combined with --dcoSetMaxMode and --dcoDisableFeat to make any and all DCO related changes at the same time in one command. This will not work if the device has been DCO frozen. NOTE: Some motherboards will issue a DCO freezelock when booted.

If DCO is frozen each time the system is rebooted, try a
    different system or add-in card to work around this.

--dcoSetMaxMode [udma# | mwdma# | nodma]
    (SATA Only)

    Use this option to set a different maximum supported DMA transfer mode using the DCO feature. This should be combined with --dcoSetMaxLBA and --dcoDisableFeat to make any and all DCO related changes at the same time in one command. The following arguments are available. Supported modes are set based on the provided maximum and all modes below the given maximum:

    udma6 - UDMA 6 and lower, including all MWDMA modes udma5 - UDMA 5 and lower, including all MWDMA modes udma4 - UDMA 4 and lower, including all MWDMA modes udma3 - UDMA 3 and lower, including all MWDMA modes udma2 - UDMA 2 and lower, including all MWDMA modes udma1 - UDMA 1 and lower, including all MWDMA modes udma0 - UDMA 0 and lower, including all MWDMA modes mwdma2 - MWDMA 2 and lower; No UDMA support mwdma1 - MWDMA 1 and lower; No UDMA support mwdma0 - MWDMA 0 and lower; No UDMA support nodma - No MWDMA or UDMA mode support listed in identify.

    This will not work if the device has been DCO frozen. NOTE: Some motherboards will issue a DCO freezelock when booted.

If DCO is frozen each time the system is rebooted, try a
    different system or add-in card to work around this.

--dcoDisableFeat [csv,list,of,features] (SATA Only)

    Use this option to disable different ATA commands and features using the DCO feature. This should be combined with --dcoSetMaxLBA and --dcoSetMaxMode to make any and all DCO related changes at the same time in one command. The following arguments are available. Specifying a feature that the drive does not support restricting or does not support at all will not be considered an error. Below is a full list of features that can be given with this option. it is unlikely a drive will support restricting all of these features.

    enable - this option will set the sensitivity to the vendor's

recommended value.
    disable - this will disable the free fall control feature. sensitivity value - set a value between 1 and 255 to control

how sensitive the detection is. A value of zero
    will set the vendor's recommended value.

--lowCurrentSpinup [ low | ultra | disable ]
    (SATA Only) (Seagate Only)

    Use this option to set the state of the low current spinup feature on Seagate SATA drives. When this setting is enabled for low or ultra low mode, the drive will take longer to spinup and become ready. Note: This feature is not available on every drive. Note: Some products will support low, but not the ultra

    low current spinup mode.

--puisFeature [ info | spinup | enable | disable ]
    (SATA Only)

    Use this option to enable or disable the power up in standby (PUIS) feature on SATA drives. Arguments:

info
    - display information about the PUIS support on the device

spinup

Note: If this is configured on the drive with a jumper, this
    command will fail.

    Note2: Not all products support this feature. WARNING: Before enabling this feature on any SAS/SATA HBA,

check the HBA documentation to see if this feature
    is supported by the HBA. Enabling this on an HBA that does not support this feature will cause the drive to stop showing up to the host OS or even in the HBA's firmware/BIOS/UEFI configuration.

--sscFeature [info | default | enable | disable] (SATA Only) (Seagate Only)

    Use this option to change or view the SSC (Spread Spectrum Clocking) mode on a Seagate SATA drive. Only change this setting if you are experiencing compatibility problems with the drive in a system. info - show current SSC state default - set to drive default mode enable - enable SSC disable - disable SSC

--sctReadTimer [info | value | default] (SATA Only)

    Use this option to set the read command timer value for synchronous commands and NCQ commands with in-order data delivery enabled. Note: this timer starts at the time that the drive processes the command, not the time it is received. When using this option, the setting is non-volatile. Use this with the --volatile flag to make the setting volatile. Use the "info" argument to get the current status of the read timer. A value of 0 means that all possible error recovery will be performed before returning status. Other values should include a unit to know the time to use. If no unit is provided, it is assumed to be the value * 100 ms Ex1: --sctReadTimer 15s for a 15 second timer. Ex2: --sctReadTimer 15000ms for a 15 second timer expressed in milliseconds Ex2: --sctReadTimer 150 for a 15 second timer with no units specified The maximum time that can be specified is 1 hour, 49 minutes, 13 seconds Using the "default" argument restores default settings. Note: On some SAT HBAs/bridges, status will not be able to be determined due to HBA/bridge limitations.

--sctWriteCache [info | enable | disable | default] (SATA Only)

    Use this option to enable or disable write cache support on a drive using SMART command transport. When using this option, the setting is non-volatile. Use this with the --volatile flag to make the setting volatile. When using this option, the --writeCache option will always return success, but no write cache changes will occur. This follows ATA spec. Using the "default" argument returns the drive to default settings and allowing the --writeCache option to work again. Use the "info" argument to get the current status of the write cache feature. Note: On some SAT HBAs/bridges, status will not be able to be determined due to HBA/bridge limitations.

--sctWriteCacheReordering [info | enable | disable | default] (SATA Only)

    Use this option to enable or disable write cache reordering support on a drive using SMART command transport. Write cache reordering allows the drive to reorder moving data out of cache to media for better performance on synchronous commands. Asynchronous commands are only affected when in-order data delivery is enabled. When using this option, the setting is non-volatile. Use this with the --volatile flag to make the setting volatile. Use the "info" argument to get the current status of the write cache reordering feature. Note: On some SAT HBAs/bridges, status will not be able to be determined due to HBA/bridge limitations.

--sctWriteTimer [info | value | default] (SATA Only)

    Use this option to set the write command timer value for synchronous commands and NCQ commands with in-order data delivery enabled. Note: this timer starts at the time that the drive processes the command, not the time it is received. When using this option, the setting is non-volatile. Use this with the --volatile flag to make the setting volatile. Use the "info" argument to get the current status of the write timer. A value of 0 means that all possible error recovery will be performed before returning status. Other values should include a unit to know the time to use. If no unit is provided, it is assumed to be the value * 100 ms Ex1: --sctWriteTimer 15s for a 15 second timer. Ex2: --sctWriteTimer 15000ms for a 15 second timer expressed in milliseconds Ex2: --sctWriteTimer 150 for a 15 second timer with no units specified The maximum time that can be specified is 1 hour, 49 minutes, 13 seconds Using the "default" argument restores default settings. Note: On some SAT HBAs/bridges, status will not be able to be determined due to HBA/bridge limitations.

--wrv [ info | all | vendor | # | disable ]
    (SATA Only)

    This option can report the current configuration of the ATA Write-Read-Verify feature, enable the feature, or disable the feature. Enabling this feature instructs the device to perform a verification of all data after it has been written. Enabling this may result in lower device performance. If write caching is enabled, this feature may return completion before writing to the medium and verifying the medium. If Write caching is disabled, the write and verification must complete before returning command status. Argument usage:

info
    - Display the current status of the feature

all - set verification on for all written sectors

vendor
    - set verification for the 1st vendor specific

    number of sectors.
