Well it sounds like write protection, which is a bit that is set on the SSD by software.
You should be able to remove write protection and a quick Google says this is possible: https://www.easeus.com/partition-master/remove-write-protection-ssd.html
Personally I'd hard nuke in Linux disk mgmt software

Nah, oddly, something odd is going on with my Sata drives and I can't work out if its coincidence or something else.
The drive fails to initiate in both macOS and W10, shows 890GB free (on a 960GB drive) and errors out when I try to nuke.
In macOS recovery mode it shows the full 960 but again unable to erase.
In BIOS it asks for a password, but I have never set one.
