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

-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

    SATA Only: ======== --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.
