I bought a used ThinkCentre M75q tiny desktop computer through kijiji. I upgraded the RAM and disk. For a disk, I bought a WD Black SN770 2TB NVMe drive. I've installed it and installed Fedora Linux on it. All fine. I don't know that much about management of NVME drives. They mostly just work. But I got curious about firmware updates. - WD only supports firmware updates through Windows or MacOS! - this machine has no Windows license (surprising but true) or installation. Less surprising, it has no MacOS license or installation. - there seems to have been a firmware update a while back (some reddit queries about it five months ago). - My unit is probably new enough that it came with that new firmware. How to check? - this article points to an NVMe tool for linux: https://opensource.com/article/21/9/nvme-cli - nvme-cli works and seems useful but I don't really know how to read the output. It does say "frmw : 0x14" which might contain the required information. - When I try to log in to WD support, they say that I must change my password (their site must have been compromised since I last logged in). When I OK that, they say that they have emailed me a link but it does not arrive. How frustrating.
