This exact SSD failed on me in a similar way. They also recently had a firmware issue that borked a bunch of drives, and they only released a fix tool for Windows users (I guess macOS/Linux users can pound sand?) I will say that the warranty service was quite good, but given the below-zero level of trust I have in SanDisk post WD acquisition, the replacement drive is going to be basically fulfilling the role of “paperweight and very oversized temporary USB drive for ephemeral sneakernet transfers”. Bought a pair of Samsung T7’s to replace it, no issues with them so far.
