🌈 --echoCommandLine

Echo the command line entered into the utility on the screen. it repeats you back to yourself, so real of it 🪞

🌈 --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.

⚠️ bestie, ONLY use this on the old USB or IEEE1394 (Firewire) stuff that refuses to work any other way. it's giving trial-and-error energy and some products might respond in ways nobody intended 😭

🌈 --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

🌟 --llInfo

Dump low-level information about the device to assist with debugging.

🌟 -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. patience is a virtue bestie ⏳

🌟 -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.

🌟 --csmiInfo

Use this option to show some information reported by the CSMI compliant driver. This includes driver information, controller information, PHY information, SAS address, and SATA signature as they were reported by the driver. This information can be useful when troubleshooting CSMI system/driver compatibility issues.

🌟 --deviceStatistics

Use this option to display the device statistics reported by the device. On SATA, this uses the Device Statistics log, and the notifications log (if DSN feature is supported) to display these statistics. On SAS, various log pages are read to collect a bunch of reported parameter information.

🌟 --showCDLSettings [raw | json]

Use this option to show the current CDL settings. Only drives supporting the CDL feature will show this data and only supported CDL settings will be shown.

Output modes:

  • raw - Show current CDL settings on screen.
  • json - Create JSON file with current CDL settings.

Time unit for time related fields in output are

  • s - seconds
  • ms - milliseconds
  • us - microseconds
  • 500 ns - 500 nanoseconds (SAS only)
  • 10 ms - 10 milliseconds (SAS only)
  • 500 ms - 500 milliseconds (SAS only)

🌟 --showConcurrentRanges

Use this option to display the concurrent positioning ranges supported by a device. Concurrent positioning ranges are used to inform which actuator is used for a given range in LBA space.

🌟 --partitionInfo

Use this option to look for a partition table and dump the list of partitions on a given disk. Currently only MBR and GPT partition tables are supported.

🍓 SATA Only 🍓

💀 --resetATAPhyEvents (SATA Only)

Use this option to reinitialize the SATA Phy event counters log page back to their default values. This can be useful when debugging cabling issues.

💀 --resetDevStats [ all | general | freefall | rotating | generr | temp | transport | ssd | zoned | cdl01 | cdl23 | vendor] (SATA Only)

Use this option to reinitialize supported device statistics to their default values. Supported statistics are indicated in the output of the --deviceStatistics option. Arguments to this option can be used to reinitialize specific pages or all supported pages.

💀 --showPhyEvents (SATA Only)

Okay so the tail end of that option is this: Use this option to display a SATA device's supported event counters. ✨

  • --smartAttributes [raw | hybrid | analyzed] — (SATA Only 💅)

bestie, the drive is about to spill its whole list of supported SMART attributes for you. Some attributes names are commonly standard and most of the others are vendor unique. But either way? The attribute thresholds are always vendor unique, no exceptions, no cap. Most attributes are informational and not used to determine a warranty return. So if you're trying to figure out whether one of the warranty attributes got tripped, use the --smartCheck command instead. And lowkey, Seagate Support does not help to analyze SMART attributes — that one's on you, queen. 👑

Output modes, take your pick:

  • raw — all hex output, for those that need every single bit. 🧮
  • hybrid — classic table view with some interpretation of some fields. Partial raw interpretation, but heads up: not all drive and firmware combinations are supported. 🙈
  • analyzed — a full breakdown of all parts of each individual attribute's data. Full raw data interpretation only available on select devices, so it's giving exclusive. 👑
NOTE: Migration to device statistics is recommended.

SAS Only: =========

  • --defectFormat [ # | shortBlock | longBlock | xbfi | xchs | bfi | chs ] — (SAS Only 🌸)

This one sets the format of the defects to output. And not all drives will support all defect modes! Like, SSDs will only support block modes, that's just the vibe. 😭

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 you pass tell it whether to get the grown, primary, or primary and grown defects from the drive. Then use the --defectFormat option to specify the mode it uses to display the defects. And 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

You can combine the above options to pull and display both defect lists at once. Two birds, one command, periodt. 💫

And then, iconic behaviour, the utility just prints its whole little name tag at you:
