Two new HDDs not showing up in BIOS or File Explorer

[andrewd084]

I just put together a new PC with three storage devices - one 500GB SSD and two 1TB HDDs, all of which are new.

When I first started it up, the only options I had in the BIOS as boot drives were the SSD and a DVD drive I used to install Windows 10. During the Windows install process, however, I saw all three drives as options when asked where I wanted the operating system located. I installed Windows to the SSD, and now I don't see the two HDDs in Explorer.

I *do* see them in the device manager, and the properties indicate that they're working fine. I also see them in the performance tab of task manager, though they're listed simply as Disk 0 and Disk 2, without drive letters (meanwhile, the SSD is "C:" as intended). I'm hoping this means they're not bricks and I just missed a step somehow, but I have no idea what that might be.

If it matters, the hardware I'm using is:

MB: ASRock X370 Taichi
CPU: Ryzen 7 1800X
RAM: 32GB (only 16 works for whatever reason - I started a different thread about that)
Graphics: EVGA GeForce GTX 1070
SSD: https://www.newegg.com/Product/Product.aspx?Item=N82E16820250087
HDDs: https://www.newegg.com/Product/Product.aspx?Item=N82E16822236625

Have you created partitions using Drive Manager?

Control Panel>Admin Tools>Computer Management>Storage>Disk Management
Right click over the drive and create simple partition.

Ah, this looks familiar, thanks!

I guess the Windows install would have done this all automatically if I'd selected one of the HDDs. I thought it'd be more "plug and play" for some reason.

Actually if the drives are listed in Disk Management but do not bear a drive letter as you've indicated, that does indicate that those drives have been partitioned/formatted. So all that is necessary is to simply use DM to assign drive letters to the drives. I assume you know how to do that. Obviously you're free to re;partition them as you please.

P.S.
On a separate note, how do you like the ASRock X370 Taichi system so far? Everything you hoped for? I've had this MB + the Ryzen 1700 (not the 'X' model) for some time, but have been too busy to assemble the build. (I'm not a gamer so I usually don't do much in overclocking). I also plan to install my 32 GB of memory.

Would appreciate hearing your review of the system. Thanks.

If you had the 2 HDDs connected when you installed Windows to the SSD, boot partitions may have been written to one or both of the HDDs. Disconnect them both and then try to boot into Windows from the SSD. If that is successful, you are OK. If not, leave the HDDs disconnected and do a clean install of Windows to the SSD.

I should revise my response in view of re:reading your initial post re the problem you experienced with the two secondary HDDs.

You did indicate the HDDs you installed were new (presumably "virgin"), which I missed. So it would appear that caswelldj's response to your query is right-on, in that you would have to utilize Disk Management to initialize, partition, and format the drives before they could be detected by the OS (with drive letters assigned to each).

Sorry for my misunderstanding.
