Hi Phil, thanks for digging around.
The HP Advisory seems to be related to a different model HDD (not used in this model laptop) though. That's not to say that it couldn't occur in other models, of course.
The new HDD has been working fine since installing it in the laptop. It's really weird that I got a SMART error when it was hooked up through USB, though.
I was satisfied with the HDD overall, and I think I'm just going to accept that it's the wine that did it.
Thanks for all of your help. If anything comes up in the future, I'll report back.
