Utility Options ===============
--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.
-h, --help
Show utility options and example usage (this output you see now) Please report
bugs/suggestions to seaboard@seagate.com. Include the output of --version
information in the email.
--hideLBACounter
Use this option to suppress the output from options that show LBA counters without
turning off all output to the screen.
--license
Display the Seagate End User License Agreement (EULA).
--modelMatch [model Number]
Use this option to run on all drives matching the provided model number. This
option will provide a closest match although an exact match is preferred. Ex: ST500
will match ST500LM0001
--noBanner
Use this option to suppress the text banner that displays each time openSeaChest is
run.
--onlyFW [firmware revision]
Use this option to run on all drives matching the provided firmware revision. This
option will only do an exact match.
--onlySeagate
Use this option to match only Seagate drives for the options provided
-q, --quiet
Run openSeaChest_Erase in quiet mode. This is the same as -v 0 or --verbose 0
-v [0-4], --verbose [0 | 1 | 2 | 3 | 4]
Show verbose information. Verbosity levels are: 0 - quiet 1 - default 2 - command
descriptions 3 - command descriptions and values 4 - command descriptions, values,
and data buffers Example: -v 3 or --verbose 3
-V, --version
Show openSeaChest_Erase version and copyright information & exit
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<#> 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.
--displayLBA [LBA]
This option will read and display the contents of the specified LBA to the screen.
The display format is hexadecimal with an ASCII translation on the side (when
available).
-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
-i, --deviceInfo
Show information and features for the storage device
--llInfo
Dump low-level information about the device to assist with debugging.
--poll
Use this option to cause another operation to poll for progress until it has
completed. This argument does not return to the command prompt and prints ongoing
completion percentages (%)
the final test result.
Full drive procedures will take a
very long time.
Used with --sanitize, or --writeSame (SATA).
--progress [sanitize | format | nvmformat]
Get the progress for a test that was started quietly without the polling option
(default). You must specify a test you wish to get progress from. Ex: "--progress
dst" or "--progress sanitize" The progress counts up from 0% to 100%.
-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.
--hours [hours]
Use this option to specify a time in hours for a timed operation to run.
--minutes [minutes]
Use this option to specify a time in minutes for a timed operation to run.
--seconds [seconds]
Use this option to specify a time in seconds for a timed operation to run.
--eraseRestoreMaxPrep
This option will attempt to restore the max LBA to the highest user addressable
sector prior to beginning a drive erasure. If any failure is encountered while
restoring the maxLBA, then an error will be indicated and the erase will not be
started or attempted until other user intervention can be completed. If a feature
is frozen, locked, or has already been used during the current power cycle, then
these things can cause a failure. The solution is to power cycle the drive, but in
some cases it may be necessary to try a different computer or adapter as commands
may be blocked by the system or automatically issued by the BIOS to lock access to
capacity changing commands. This option will handle the ATA HPA (Host Protected
Area), AMAC (Accessible Max Address Configuration), HPA Security Extension, and DCO
(Device Configuration Overlay) features in accordance with the specifications. If
the restore completes without error, then the erase will proceed and additional
errors will only be in relation to those erasure methods.
--showEraseSupport
This option checks the drive to determine which methods of data erasure are
supported and lists them, from fastest to slowest.
WARNING: Some erase methods may affect all LUNs/namespaces for devices
with multiple logical units or namespaces.
--zeroVerify [full | quick]
Use this option to verify drive content, whether it's set to zero or not. This
operation will read user accessible address and validate if content at that address
is zero or not. Validation modes:
full - Complete drive will be scanned for verification. quick - 0.1% of total
capacity will be scanned for ID and OD validation along with
2 random addresses from 10000 equal size sections each.
SATA Only: ========= --ataSATsecurityProtocol [enable | disable] (SATA
only)
This option can be used to force enable or disable using the ATA security protocol
as specified in the SAT specification. By default, the tool will use this method
when it is supported to allow the SATL to understand and manage the security
commands being performed and prevent other issues.
--ataSecPassword ["ASCII password" | SeaChest | empty]
(SATA only)
Use this option to specify a password to use with an ATA security operation. If
specifying a password with spaces, quotes must be used. If SeaChest is given, the
default SeaChest password will be used. If empty is given, an empty password will
be used. Examples:
"This is a valid password" ThisIsAlsoValid "This password uses \"quotes\" "This
password is \/\/eird"
--ataSecPassType [user | master]
(SATA only)
Use this option to specify if the password being given with the --ataSecPassword
option is a user or a master password. If this option is not provided, user is
assumed.
--ataSecPWMod [byteswapped | zeropad | spacepad | fpad | leftAlign | rightAlign |
uppercase | lowercase | invertcase] (SATA Only)
Use this option to have the utility make modifications to the ATA security password
to attempt other various ways it may be sent by a system bios. These are not
guaranteed to work, but may help unlock a drive that was locked by a BIOS that
encoded the password in a unique way. This option can be presented multiple times
to select multiple modificaitons. EX: --ataSecPWMod byteswapped --ataSecPWMod
invertcase
byteswapped - byteswaps the password. EX: blah -> lbha zeropad - zero pads the
password if less than 32 characters spacepad - space pads the password if less than
32 characters fpad - pads the passwords with Fh (all 1's) if less than 32characters
leftAlign - left aligns the password in the buffer rightAlign - right aligns the
password in the buffer uppercase - sends the password as all uppercase lowercase -
sends the password as all lowercase invertcase - switches uppercase for lower, and
lowercase for upper
Data Destructive Commands ========================= Data sanitization capabilities:
Recommendation - Restore the MaxLBA of the device prior to any erase in
order to allow the drive to erase all user addressable sectors. For ATA devices
this means restoring HPA + DCO / AMAC to restore the maxLBA. Restoring the MaxLBA
also allows full verification of all user addressable space on the device without a
limitation from a lower maxLBA.
Clear - Logical techniques are applied to all addressable storage
locations, protecting against simple, non-invasive data recovery techniques.
Clear, Possible Purge - Cryptographic erase is a purge if the vendor
implementation meets the requirements in IEEE 2883-2022.
Purge - Logical techniques that target user data, overprovisioning,
unused space, and bad blocks rendering data recovery infeasible even with
state-of-the-art laboratory techniques.
This utility does not support clear/purge verification yet. All labels are written
according to the expectation that the device firmware will meet these capabilities as
defined in the appropriate standards from T10, T13, SATA - IO, and NVMexpress.
=========================
--overwrite [starting LBA]
(Clear)
Use this option to start an overwrite erase at the specified starting LBA. Combine
this option with overwriteRange or time options (hours, minutes seconds) to erase a
portion of the drive.
--overwriteRange [range in # of LBAs]
(Clear)
Use with the overwrite option (--overwrite) to erase a range of LBAs on the
selected drive.
--pattern [repeat:asciinospaces | random | increment:startValue | file:filename]
Use this option with overwrite, sanitize, and format unit operations to write a
specific pattern to a range of LBAs or the whole drive.
* repeat - without spaces, enter an ASCII text string or a hexadecimal string
terminated by a lower case "h". This pattern will be repeated until it fills the
logical size of the LBA. i.e. helloword or FFFFFFFFh Note: A hexadecimal pattern
will be interpreted as a 32bit unsigned integer. 4 hex bytes (8 characters) must be
given for a hex value to be used. Ex: 1F037AC8h or 0000FFFFh * random - the entire
logical sector size will be filled with random bytes.This pattern will be written
to all LBAs in the desired range. * increment - enter the starting numerical
value. Starting with this value, each byte will be written with 1 + previous value.
* file - user supplied file name to use for a pattern. The file will be truncated
or padded with zeros to the logical sector size Note 1: Each file will be
interpreted as a binary file. Note 2: A path must also be provided if the file is
not in the
local directory.
Note 3: Sanitize Overwrite on SATA only supports a 32bit pattern.
The file option will get truncated to a 32bit pattern for SATA products.
--performQuickestErase
This option checks the drive to determine which methods of data erasure are
supported and determines which is the quickest to erase ALL data on the drive. It
then starts the quickest erase. Combine this option with the --poll option to
enable polling for progress on the fastest erase. Note: Some erase methods require
polling and will have polling enabled by default. Note 2: If revertSP is the
fastest, it will not be started since the drive PSID must be passed in on the
command line.
WARNING: Some erase methods may affect all LUNs/namespaces for devices
with multiple logical units or namespaces.
--sanitize [info | blockerase | cryptoerase |
overwrite | freezelock | antifreezelock] (Purge)
Use the info argument to show supported sanitize operations. Optionally, use
blockerase, cryptoerase, or overwrite to start a sanitize operation. Adding the
--poll option will cause openSeaChest_Erase to poll the drive for progress until
the operation is complete, or has aborted for some reason. All sanitize erase
operations are persistent across a power cycle and cannot be stopped Example:
--sanitize blockerase --poll
* blockerase on some solid state drives is very fast at less than one (1) second,
while others may take more that 30 seconds This operation performs a physical low
level block erase operation on all current, past, and potential user data. The
contents on user data are indeterminate upon completion.
* cryptoerase is very fast at less than one (1) second. It changes the internal
encryption keys that are used for user data causing all previous data to be
useless.
* overwrite is a physical overwrite on all current, past, and potential user data.
The ATA and SCSI specifications allow a user defined pattern and multiple passes.
openSeaChest_Erase will use a zero pattern and a single pass for this operation.
* freezelock is a command to block processing of sanitize operations until a power
cycle is performed on a device. It is only available on ATA drives. Once this
command has been sent, the freezelock status becomes immediate and cannot be
cleared until the drive has been powered off. All sanitize commands, except a
sanitize status will be aborted.
* antifreezelock is a command that is designed to block a freezelock command from
locking out the sanitize feature set. It is only available on ATA drives that
support the ACS3, or newer specification.
WARNING: Sanitize may affect all LUNs/namespaces for devices
with multiple logical units or namespaces.
--trim or --unmap [starting LBA]
Use one of these options to start a trim or unmap operation on a drive at the
provided LBA. A range must also be provided with the range option.
--trimRange or --unmapRange [range in # of LBAs]
Use one of these options to specify a range to trim or unmap on a drive. A starting
point must be specified with the --trim/--unmapRange option.
--writeSame [starting LBA]
(Clear)
Enter a starting lba to begin a write same on to erase a range of data on the
drive. On SCSI devices, this uses the writesame16 command. On ATA devices, this
uses the SCT writesame feature. Combine this option with the writeSameRange option
to select the range. This operation will write 0's to the device for the specified
range. For SATA drives, this option will poll for progress until the write same has
completed. SAS/SCSI drives will hold the tool busy until the write same has
completed without progress indication since this is not possible on SAS/SCSI due to
specification limitations on how write same was defined. On SATA, if any other
commands are sent to the drive while it's performing a write same, the write same
will be aborted. NOTE: On SAS/SCSI drives this command is optional. Additionally,
the range may be limited to much less than the full device
size. Due to the history of this command, there is not a great way to confirm
support in all cases. Some ranges will be too large, and some devices may or may
not allow writing the full medium in a single command. If you wish to write an
entire device, consider a different command such as format unit or sanitize
overwrite to accomplish this.
--writeSameRange [range in # of LBAs]
Specify a range to writesame to. Use this option with the writeSame option in order
to begin a write same operation.
SATA Only: ========= --ataSecureErase [normal | enhanced] (SATA only) (Clear
| Purge)
Use "normal" to start a standard ATA security erase (Clear) or "enhanced" to start
an enhanced ATA security erase (Purge).
ATA Security Erase takes a very long time to complete at approximately three (3)
hours per Tera-byte (HDD). Some Seagate SED models will perform a quick
cryptographic erase in enhanced mode and the time for completion is reported as 2
minutes by the drive, but will take only seconds. This industry standard command
begins by locking the drive with a temporary password which is cleared at the end
of the erasure. Do not run this command unless you have ample time to allow it to
run through to the end. If the procedure is interrupted prior to completion, then
the drive will remain in a locked state and you must manually restart from the
beginning again. The tool will attempt to automatically clear the password that was
set upon failure. The default password used by the tool is "SeaChest", plain ASCII
letters without the quotes
* normal writes binary zeros (0) or ones (1) to all user data areas.
* enhanced will fill all user data areas and reallocated user data with a vendor
specific pattern. Some Seagate Instant Secure Erase will perform a cryptographic
erase instead of an overwrite.
SAS Only: ========= --fastFormat [fast format mode] (SAS Only) (SBC4 required)
Use this option with the --formatUnit option to run a fast format. Changing sector
sizes is intended for supported Seagate products used in some hardware RAID
configurations. Please consult your hardware RAID documentation for information
about compatibility and using 4K native sectors before using this option! Software
RAID or individual/JBOD drive solutions will see no benefit as modern file systems
and modern operating systems are already 4K aware even on 512 emulation drives.
Modern operating systems already align file systems to 4K boundaries required by
these drives for optimal performance. Performing a sector size change is data
destructive and has a risk that the adapter, driver, or operating system may not
know how to communicate with the device once this has completed.
[49m[38;5;9m There is an additional risk when performing a low-level fast format
that may
make the drive inoperable if it is reset at any time while it is formatting.
[0m Available fast format modes:
0 - This is a standard format unit command. All logical
blocks will be overwritten. This command will take a very long time
1 - This is a fast format unit command keeping existing
data in physical sector. This option can be used to quickly change the the logical
sector size between 5xxe and 4xxx. The media may be readable, but data may be
unspecified or may return errors on read access according to it's error processing
algorithms.
2 - This is a fast format unit command that can change the
logical sector size quickly. Media may or may not be read accessible until a write
has been performed to the media.
[49m[38;5;11m WARNING: Any interruption to the device while it is formatting may
render the
drive inoperable! Use this at your own risk!
WARNING: Set sector size may affect all LUNs/namespaces for devices
with multiple logical units or namespaces.
WARNING: Disable any out-of-band management systems/services/daemons
before using this option. Interruptions can be caused by these and may prevent
completion of a sector size change.
WARNING: It is recommended that this operation is done from a bootable environment
(Live USB) to reduce the risk of OS background activities running and triggering a
device reset while reformating the drive.
[0m --formatUnit [current | new sector size] (SAS Only) (Clear)
This option will start a format unit operation on a SAS drive Use "current" to
perform a format unit operation with the Sector size currently being used,
otherwise enter a new sector size to use upon format completion. This command will
erase all data on the drive. Combine this option with --poll to poll for progress
until the format is complete. Changing sector sizes is intended for supported
Seagate products used in some hardware RAID configurations. Please consult your
hardware RAID documentation for information about compatibility and
supported/required sector sizes!
WARNING: Format Unit may affect all LUNs/namespaces for devices
with multiple logical units or namespaces.
WARNING: Customer unique firmware may have specific requirements that
restrict sector sizes on some products. It may not be possible to format/ fast
format to common sizes like 4K or 512B due to these customer requirements.
NVMe Only: ========= --nvmFmtMetadataSet [ xlba | separate ] (NVMe Only)
Use this option to specify how metadata is transmitted to the host system.
Options:
xlba - metadata is transferred as part of the logical block data separate -
metadata is transferred as a separate buffer
Note: Not all devices support specifying this. If this option is not provided, the
NVM format will reuse the current setting.
--nvmFmtMS [ # of bytes for metadata ]
(NVMe Only)
This option is used to specify the length of metadata with a requested logical
block size. The device must support the combination of logical block size and
metadata size or the format will be rejected by the device.
--nvmFmtNSID [all | current]
(NVMe Only)
This option changes the NSID used when issuing the NVM format command. This can be
used to control formatting an entire device or a specific namespace if the device
supports specifying specific namespaces for a format command. Not all devices
support this behavior. This has no effect on devices that do not support targeting
a specific namespace and will format the entire device If this option is not given,
the format will be issued to all namespaces by default.
--nvmFmtPI [ 0 | 1 | 2 | 3 ]
(NVMe Only)
Use this option to specify the protection type to format the medium with. Note:
Not all devices support protection types. If this option is not provided, the NVM
format will reuse the current setting.
--nvmFmtPIL [ beginning | end ] (NVMe Only)
Use this option to specify the location protection information in an NVM device's
metadata. Note: Not all devices support specifying this. If this option is not
provided, the NVM format will reuse the current setting.
--nvmFmtSecErase [none | user | crypto] (NVMe Only)
(None | Clear | Clear, Possible Purge)
This option is used to specify the type of erase to perform during an NVM format
operation. All user data will be inaccessible upon completion of an NVM format, no
matter the erase requested. Options:
none - no secure erase requested (previous data will not be accessible,
however the media may not have been erased by the controller.)
user - requests all user data is erased by the device. (Clear) crypto - requests a
cryptographic erase of all user data. Note: this mode
is not supported on all devices. (Clear, Possible Purge)
--nvmFormat [current | format # | sector size]
(NVMe Only)
This option is used to start an NVM format operation. Use "current" to perform a
format operation with the Sector size currently being used. If a value between 0
and 15 is given, then that will issue the NVM format with the specified sector
size/metadata size for that supported format on the drive. Values 512 and higher
will be treated as a new sector size to switch to and will be matched to an
appropriate lba format supported by the drive. This command will erase all data on
the drive. Combine this option with--poll to poll for progress until the format is
complete. A data sanitization compliant with IEEE 2883 Clear requires the
--nvmFmtSecErase option to be provided. Without this option the controller may not
erase all user data and substitute returning zeroes for performance instead.
