It's not obvious to me what the concern is - 18TB drives have only existed for two years so even if the labels are completely fake they are not that old. On the other hand, going and buying a drive in a bag from a random guy on eBay and expecting it to actually be new is kind of silly, they are only $299 overnighted on Amazon so if you actually care about your data just eat the extra 60 bucks. $240 seems in line with "I found these at work, I don't think anyone used them, take your chances" - I'd put my media on them, but not my actual data.
