Well I got a case off Amazon and popped the ssd card in it. The results were the same as the original case, it was requesting to be initialized. I didn’t bother with recovery software to see if anything was readable.

I initialized it in the new case and 2TB of storage showed up. (The shielding in the original case is an adhesive foil and is hard to get off and even tougher to get back on. The new case is metal.)
Let me guess, you’re getting around 250 MB/s write and 400 MB/s read now. Such a ****** thing for Sandisk / WD to do.
 
I tried to copy files to the ssd card in the new enclosure: I got reliable FAILURES. I’m thinking the card IS bad. It would unmount itself randomly. Where’s the closest trash can?
