How to Flash the Seagate Exos X16 from the SN02 to SN03 Firmware

I recently purchased some of these Seagate Enterprise drives, and looks like they shipped with the SN02 Firmware. Upgrading on Windows is quite easy. Just be aware I tested with the drives still clean, while not in RAID.

If you were to run this on a live array, I strongly recommend doing one disk at a time, and taking the disk out of the array while you do it, to avoid any potential issues.


1 – Download the newest firmware from the seagate support page, by inputting your serial number here:

2 – Extract the contents, and copy the following to C:\Seachest:

3 – Open a command prompt in administrator mode, and type SeaChest_Firmware_270_11923_64 --scan to get a list of drives:

4 – Run the following command to update your drive, where “PX” is the Handle for the specific drive you want to update. In this example, I’m using PD0: SeaChest_Firmware_270_11923_64 -d PX --downloadFW EvansExosX16SATA-STD-512E-SN03.LOD

5 – Re-run the scan command, to confirm the firmware is indeed updated:

6 – And that’s it! Enjoy the latest firmware for your Exos drive!

    1. Oh, looks like wordpress changed the command slightly. If you copied the command from my page, look closely at the -downloadFW portion, it should contain two “-” in front of the downloadFW. Let me know if this helps! I’ll try to update the page to reflect it.
