Related, someone decompiled Samsung’s 840 EVO ssd firmware, before Samsung later started encrypting it: http://www2.futureware.at/~philipp/ssd/TheMissingManual.pdf

Came across it looking how to deal with multiple different samsung drives caught in bad states due to shitty firmware. My original salty post warning about vendor branded Samsung drives on eBay is here: https://news.ycombinator.com/item?id=37165189

This deserves its own blog post and HN submission. Since SSDs have been 2x to 4x prices people are now more likely to buy used and could get burned.

BTW thank you for raising this.
