I emailed Crucial on Sunday and got a reply this morning with questions, lots of questions.
I copied it into Word and replied inline in red to see if it will help them, it is three pages long.
Will have to see what happens. As usual I can't tie the SSD to an invoice, I have 2 of the same make/size but there is nothing on the invoice to identify them. One was purchased October 2024 the other January 2025 so both in warranty.
