Welcome to the openSeaChest open source project!
BINARIES and SOURCE CODE files of the openSeaChest open source project have been made available to you under the Mozilla Public License 2.0 (MPL-2.0). The openSeaChest project repository is maintained at https://github.com/Seagate/openSeaChest.
Compiled binary versions of the openSeaChest utilities for various operating systems may be found at https://github.com/Seagate/ToolBin/tree/master/openSeaChest
This collection of storage device utility software is branched (forked) off of
an original utility collection called the Seagate SeaChest Utilities by Seagate
Technology LLC. The original SeaChest Utilities are still available at
www.seagate.com or https://github.com/Seagate/ToolBin/tree/master/SeaChest.
Binary versions are available for Linux or Windows, with the Windows versions
signed by Seagate Technology LLC.
openSeaChest is a collection of programming libraries for storage devices and comprehensive, easy-to-use command line diagnostic tools that helps you quickly determine the health and status of your storage product. It includes several tests that will examine the physical media on your storage device.
Here is an overview presentation we gave at the Storage Networking Industry Association - Storage Developer Conference 2018 that describes the design architecture for the opensea API and openSeaChest storage resource management utilities:
(Note: The openSeaChest team has the utmost respect for the highly regarded sg3_utils, hdparm, sdparm and nvme-cli open source projects. Since this is all pretty low-level stuff, we chose the presentation title "What's better than sg3_utils, hdparm, sdparm?" only to grab the attention of a few extra people attending the SNIA SDC 2018 conference.)
opensea-common - Operating System common operations, not specific to storage standards. Contains functions and defines that are useful to all other libraries.
opensea-transport - Contains standard ATA/SCSI/NVMe functions based on open standards for these command sets. This layer also supports different transporting these commands through operating systems to the storage devices. Code depends on opensea-common.
opensea-operations - Contains common use cases for operations to be performed on a storage device. This layer encapsulates the nuances of each command set (ATA/SCSI) and operating systems (Linux/Windows etc.) Depends on opensea-common and opensea-transport.

If this is your drive, you should always keep a current backup of your important data.
Many tests and commands are completely data safe, while others will change the drive (like firmware download or data erasure or setting the maximum capacity, etc). Be careful using openSeaChest because some of the features, like the data erasure options, will cause data loss. Some commands, like setting the maximum LBA, may cause existing data on the drive to become inaccessible. Some commands, like disabling the read look ahead buffer, may affect the performance of the drive. Seagate is not responsible for lost user data.
Important note: Many tests in this tool directly reference storage device data sectors, also known as Logical Block Addresses (LBA). Test arguments may require a starting LBA or an LBA range. The predefined variable 'maxLBA' refers to the last sector on the drive. Many older SATA and SAS storage controllers (also known as Host Bus Adapters [HBA]) have a maximum addressable limit of 4294967295 [FFFFh] LBAs hard wired into their design. This equates to 2.1TB using 512 byte sectors. This also means accessing an LBA beyond the 2.1TB limitation either will result in an error or simply the last readable LBA (usually LBA 4294967295 [FFFFh]) depending on the actual hardware. This limitation can have important consequences. For example, if you intended to erase a 4TB drive, then only the first 2TB will actually get erased (or maybe even twice!) and the last 2TB will remain untouched. You should carefully evaluate your system hardware to understand if your storage controllers provide support for greater than 2.1TB.
Note: One gigabyte, or GB, equals one billion bytes when referring to hard drive capacity. This software may use information provided by the operating system to display capacity and volume size. The Windows file system uses a binary calculation for gibibyte or GiB (2^30) which causes the abbreviated size to appear smaller. The total number of bytes on a disk drive divided by the decimal calculation for gigabyte or GB (10^9) shows the expected abbreviated size. See this FAQ for more information http://knowledge.seagate.com/articles/en_US/FAQ/172191en?language=en_US.
Seagate offers both graphical user interface (GUI) and command line interface (CLI) diagnostic tools for our storage devices. SeaTools for Windows and SeaTools Bootable for end users are the two most popular GUI tools. These tools support 15 languages.
openSeaChest diagnostics are command line utilities which are available for expert users. These command line tools assume the user is knowledgeable about running software from the operating system command prompt. CLI tools are in the English language only and use "command line arguments" to define the various tasks and specific devices. openSeaChest diagnostics are available for both Linux and Windows environments.
Linux versions of openSeaChest tools are available as stand alone 32 or 64-bit executables you can copy to your own system. Windows OS versions of openSeaChest diagnostics are also available.
Technical Support for openSeaChest drive utilities is not available. If you have the time to send us some feedback about this software, especially if you notice something we should fix or improve, we would greatly appreciate hearing from you. To report your comments and suggestions, please use this email [email protected]. Please let us know the name and version of the tool you are using.
openSeaChest drive utilities support SATA, SAS, NVMe and USB interface devices.
openSeaChest_Basics - Contains the most important tests and tools.
Other openSeaChest "break out" utilities are available and listed below which offer more in-depth functionality in specific areas. These are:
openSeaChest_Configure - Tools to control various settings on the drives are brought together into this one tool. Typical commands, for example, include Write Cache and Read Lookahead Cache enable or disable.
openSeaChest_Erase - The focus is on data erasure. There are many different choices for erasing data from simple boot track erase to full cryptographic erasure (when supported). Be sure to back up important data before using this tool. Seagate is not responsible for lost user data. This tool only works on Seagate drives.
openSeaChest_Firmware - Seagate products are run by firmware. Having the latest firmware can improve performance and or reliability of your product. Seagate recommends applying new firmware to enhance the performance and or reliability of your drive. Most products may see one or two firmware updates within the early life of the product.
openSeaChest_Format - Storage products which utilize the SAS, SCSI or Fibre Channel interfaces are able to perform a full low-level media format in the field. The SCSI Format Unit command offers many specialty options to accommodate a variety of conditions and to fine tune the procedure. This complex command deserves its own "break out" utility.
openSeaChest_GenericTests - Read Tests are the original disk drive diagnostic which is to just read every sector on the drive, sequentially. This tool offers several common read tests which can be defined by either time or range. In addition, the Long Generic test has the ability to repair problem sectors, possibly eliminating an unnecessary drive return.
openSeaChest_Info - Historical generic activity logs (like total bytes written and power on hours) and performance logs (like temperature) are available for analytical review. Identification and inquiry data stored on the drive is also provided. A view of SMART and device statistics is available when supported by the drive.
openSeaChest_Logs -
openSeaChest_NVMe -
openSeaChest_PowerControl - Seagate disk drives offer a multitude of options to manage power. This tool manipulates the various power modes.
openSeaChest_Security - Various settings are available on modern Seagate disk drives which may be locked and unlocked. These settings may interact with the operating systems and systems BIOS. Options also include cryptographic erase for Self-Encrypting Drives (SED).
openSeaChest_SMART - This tool provides a closer look at the collected SMART attributes data. SMART stands for Self-Monitoring, Analysis and Reporting Technology. Short Drive Self Test is included as one of the standard SMART commands. In addition, the DST & Clean test has the ability to repair problem sectors, possibly eliminating an unnecessary drive return.
