Mac Mini Disc Not Ejected Properly

[Brentor]

I keep getting this message in respect of one of my external M.2 NVMe SSDs. I worked through the recommended fixes eg a new certified cable, changed the power settings, used a direct connection rather than use a hub etc, but it keeps coming back, in most cases I have not even used the drive. Possibly a faulty enclosure but other than the annoying message all is fine.

I have found a way to disable the message but thus is probably not ideal.

Anyone else have this problem?

Been getting this a few times randomly with ejecting SD cards from my external card reader on the iMac - didn't have the problem before updating to Sequoia 15.8.
If you updated to the latest macOs, did it relate time-wise?
