I just bought a seagate 1TB hard drive so I could use it in addition with my WD 1TB hard drive that I had when I first build my computer. After I installed my hard drive, I found that it shows up in my BIOS, but it doesn't show up in Disk Management.
I've already tried what was suggested in these articles:

Any suggestions would help,
Thanks
 
Hey there, tacoshmaco89!

If it does show in BIOS, but nowhere else, it's possible that the SATA cable or port is faulty. I'd suggest you to try plugging it in another SATA port on the motherboard, and trying with a different SATA cable. I'd also recommend you to check if you've enabled the SATA port in question from BIOS.
As a last resort, you can try resolving the issue by resetting BIOS, however it will get your settings back to factory defaults and you'd need to re-configure them afterwards. Here's a tutorial about how to get this done: http://www.wikihow.com/Reset-Your-BIOS

Hope it helps. Keep me posted! :)

I had similar problem wiith my added disk drive when I upgraded. Don't know if this will help you or not, but I had to go to device manager IDE ATA/ATAPI controllers and delete all ATA channels, back out and restart. Let Windows find all ATA devices and there were both my disk drives. hope this helps you.

I had this happen after the Anniversary Update for windows 10. I don't know if that has anything to do with it or not.

I solved the problem by going into Device Manager and right-clicking IDE ATA/ATAPI Controllers and choosing Scan for Hardware Changes. It immediately discovered my HDD that wasn't showing up before. A message even popped up in the Message Center asking what I wanted to happen with Removable Drive E:

I pulled the C: HDD from a desktop system that I had recently upgraded from Win7 to Win10. I had a failed BIOS flash to the system and needed to get some files off the drive. But I found I could not read the drive on another Win7 or Win10 system using a USB to SATA adapter or by installing the drive in the system using a SATA cable. Windows reported that I needed to format the drive. The drive did show up in the BIOS setup but not in Windows Disk Manager. When I check the drive with a Partition Manager utility it showed the drive as RAW. I finally was able to read the drive using this trick.

There is "Memory Diagnostic Tools" in Windows Admin Tools. In Win10 it is called "Windows Memory Diagnostic". I ran this test and Windows rebooted. After the test my drive was in Windows Explorer and I could read all the data on it. I don't know why this worked but thankfully it did.
