I been running smartctl -t long on a drive for about 2 days now and it seems to be stalled at 10%. short and conveyance both passed. I have to send 1 of 2 drives purchased back I found badblocks with badblocks (none on this drive and I'ts made over a pass already). I'm just wondering if I should be concerned about this.
