Dual HDD incompatibility in laptop

Hi all, new here, so I'll jump straight in with the problem(s) at hand. The two identical HDD's that were in my laptop were getting smart read errors and were beginning to fail, so I removed the one that had my OS on it as that was the more problematic one. Well, it turns out that I had a spare one on hand - but is a different brand and is at half the capacity of the other two. So after checking the BIOS if there were any compatibility issues (there weren't), I went right ahead and setup Windows.

But here's the thing: After setting everything up, Windows is not picking up the secondary HDD but is being recognized as a Peripheral under Device Manager, Msinfo32 etc but is not being picked up as a storage device under Computer Management or My Computer. And there are no jumper switches on the HDD's nor are there any options in the BIOS to set one up as a slave/secondary HDD, only in which order they boot.

Also, under HD Tune the temperature threshold for the one with my OS on it (this is the good one) is rated at 40c and is reading out at 60c. Faulty sensor?


Any help would be greatly appreciated.

Well derp me, that done it, thanks. I was just looking in there too.

I still find it odd that I had to assign it whereas with the other drive I never had to take that step.

Well, problem solved anyway.

However, I'm still worried about the temp readout on my good drive.

60C is going to feel very hot to the touch, and it well kill the HDD. If it does not feel that hot then it's a funky sensor. Is the fan running OK?

Mucked that one up too. This is what I am getting:



Now I don't have a Thermo Gun so I cannot check for a readout that way, but it's not hot to the touch but warm, and the airflow and heat to the rest of the system is normal. Should I be worried?

I'd have to assume that the sensor has gone in it. The HDD actually came out of my old HP Pavilion DV9700 that overheated (HP screwed up with that model, poor airflow, dodgy welds on the GPU etc)

Edited post above. And the HDD is about a year older but has had far less use.
