Previously working HDD no recognised by Windows

My hard drive used to work fine until about 2 months ago when I reset my computer.
After I reset my computer, the Hard Drive was no longer seen in Windows Explorer (Windows runs from my SSD, which works perfectly).
since then I have run quite a few tests and stuff to get it working, until eventually I set it down and called it a day. But now I am determined to get it working again, I'm asking here.
Here are some of my findings and other important info:

- It is a 2Tb Seagate Barracuda
- The Hard Drive is recognised in the BIOS (along with how much space it holds)
- Sometimes I find if I RESTART (not shut down) the computer, the BIOS will no longer see it after it has booted back up
- The SATA Cable and Motherboard Port are working fine, as I connected it to a different Hard Drive I had lying around, and it worked fine.
- If the Hard Drive in question is connected, the computer takes substantially longer to boot up (~3mins compared to usual 13 seconds)
- Windows Explorer doesn't see it EVER
- Device Manager sees it as an "unknown device" under the 'Disk Drives' tab
- Disk Management is very interesting - it says it is "Not initialised":

If I right click on Disk 1 and press "Initialise":

After I press "OK":

If I right click on Disk 1 and press "Properties", and then go on the "Volumes" tab:

If you want any other information/screenshots from Device Manager or anywhere else, I will be more than happy to do so.
- Once upon a time I had Ubuntu on the hard drive, before I had Windows and used the SSD. On my BIOS, it says "Ubuntu" on the drive. If i try to boot from ubuntu however, the screen goes black for about a minute before the Windows 10 logo comes and Windows just starts loading from my SSD. (Please note that I don't want a fix to this problem, as I don't want to use Ubuntu)

I understand that all this information is so specific, but I am only expecting people to know about a few of these things, or similar issues involving similar symptoms and be able to tell me how the problem was fixed then.
All I want to know is how to get Windows to see and recognise my Hard Drive, and know that it is 2Tb, not 0B as everything on Windows is telling me it is. As I said, if you need any more info/screenshots, just tell me and I will do so.
I would much prefer that I get to keep the data that is on the Drive, however it is not so important that I wouldn't be prepared to format the drive IF I knew that would fix it - mostly because I can't buy a new 2Tb drive, so losing all my data would be better than not having any storage at all.

Please do what you can to help, and I thank you in advance :)

  1. Apparently after you "reset" your computer whatever data existed on the drive was obliterated. The likelihood that the data can be recovered from a practical, reasonable cost basis is virtually nil. While there are "data recovery" programs (freely-available & commercial) available on the net and you might want to give them a try, the chances any of them will recover your data is highly unlikely. Commercial data recovery entities exist as you probably know but the cost involved would most likely be prohibitive unless the data involved is critical for you to recover. And there's no guarantees there either.

    Anyway...

    The likelihood is your drive is not defective so that it can be used as your HDD. Just continue the process of initializing, partitioning, & formatting the disk as you would ordinarily do for any new "virgin" disk. Understand if you do this any further attempt at recovering prior data on the drive will be next to impossible. So don't pursue that course of action if you still have it in your mind to recover data. Capiche?

    How would I go about doing so for this disk? The BIOS is basically the only thing that sees it - is there a way to do it from the BIOS?
  3. I think you understand this, but just to ensure there's no misunderstanding, once you initialize, partition, and format the HDD (assuming you will be able to do so), that process will effectively eliminate any practical chance of recovering any data on that disk.

    Based on the previous info you provided it appears that Seagate HDD is not defective and it's a usable drive. But that is not definitive. (It's been more than two weeks since your last post re this issue so I have no idea what actions (if any) you've taken re that drive.)

    Anyway...connect the drive internally in your system (I guess you're working with a desktop PC) and test the drive with Seagate's SeaTools diagnostic program to determine the health of the drive. See http://www.seagate.com/support/downloads/seatools/seatools-win-master/
    (You can also connect the HDD as a USB external drive for testing purposes if that's more practical.)

    Assuming the drive is non-defective, use Disk Management to initialize, partition, and format the drive. I assume you know how to do these things but if not, do a Google search for detailed instructions re the process.

    (I havent used the Seagate tool yet)
    I think I was unclear in my previous message. I am unable to format the drive from Windows, as windows does not recognise it.
    Therefore I don't really know how to go about formatting and partitioning it (seeing as though the BIOS is the only thing that recognises it for a 2TB seagate drive)
