Second hand SAS drive - counters were reset

TrueNAS General

Well if it passed badblocks & then a smart long test, I’d argue the drive is worth putting into production.

Edit: sorry - meant to reply to OP, but clicked your post instead.

More or less a week later, all tests have now completed. No errors.

@Fleshmauler I concur, the drive seems healthy. I would still source different sizes for my next ones based on the backblaze report. It’s just the 10TB version which is more prone to failures.

Thank you all for the assistance, very much appreciated!
