I just got done talking to Amazon about a 512GB Samsung 960 PRO SSD I bought that was clearly tampered with. I plugged it in and it already had Windows installed on it... ok, weird... Go to format, see that it's only a 256GB. Unplug it and examine closer, it's pretty obvious the guy took the Samsung stickers off and placed them on a 256GB Hynix SSD, then returned that for a refund.
Anyway, I plug it back in and start snooping, he has loads of homework on there with his name all over it, address in documents, etc... Bonus is that Amazon said I could keep this one and they're sending a new one next day.
