Re:WD Passport 4TB drives don't support WRITE SAME command by HelloNurse on Thursday March 26, 2020 @03:37PM (#22697099)
The (potential) security issue is that the operating system fails to clear disk space, possibly incorrectly assuming it has actually been cleared.

Except that it receives an error, so if it's assuming that, it's wrong.

This command is not mandated to be supported. Therefore, if an OS assumes it is supported, that's an OS problem, not the drive.

I don't see how this could occur. Either you do WRITE SAME and it works or it doesn't and you have to manually issue WRITE commands.
