I bought this new SSD in Dec 2025 to work as a TimeMachine back up for my M4 Mac Mini. It worked fine for the first 3 months, now the Mac doesn’t even recognize it, cannot perform First Aid (this has fails) and I cannot even mount the drive.
I have followed all of the advice I’ve found online and nothing is working. It’s just dead.
It is now outside of it’s return window with amazon, so how do I claim a refund from SanDisk or at least a replacement?
