You never know for sure, but in this very recent post, it says the drive came in a sealed bag, and I have purchased new (used stock) from goharddrive myself in the past.
Bolt HDD Upgrades in 2021
Well they all come in sealed bags, even refurbs. However GHD is good about answering questions about new/OS vs refurb. They have sold both new/OS and refurb ABB200s in the past. Normally they list if item is refurb on their site but since this going through Walmart I'd double check.
Just a comment on refurbs in general. I wonder what exactly refurb mean on a hard drive? I've seen multiple info. Many seem to just format/clean the drive and sell it as refurb. Some check for bad sectors, some do not. Some reset the hours to zero, some do not. I bought a 3TB refurb from Newegg. Got a drive with over 40K hours and some reallocated sectors to boot. I suppose I prefer a drive where they do NOT reset the hours to zero, if they do you will never know how "used" it is, like mine, over 40K hours. I will say this, I doubt anyone REALLY refurbs a hard drive. Like taking apart, new parts etc. Soooooo, I'd avoid refurbs. Especially on 2.5" drives that will see heavy use in a Tivo.
