[SOLVED] I've just reinstalled windows on the ssd but I can't find the hdd anymore

Recently I've changed my mobo, cpu and ram, and yesterday I reinstalled Windows 10 after a secure erase of the ssd.
NB: I did the erase and the installation with the 3 hdd disconnected.

Now, the problem is that when I connected the hdd to the mobo, after completing the installation of windows 10, 2 of them worked fine, but the other one can't be find on "This PC".
So I checked if it was broken using "CrystalDiskInfo" and it says it's ok.
And then I checked on disk management, where it doesn't appear in the upper half, but it appears in the lower half, but with a yellow triangle on the icon:
https://ibb.co/8snXtpT (the text says "disk 2", "dynamic" and "external")

So, what could be the problem? Even if I have to format it, is there a way to recover files on the hard disk?

If it appears in the bottom but not the top is means the disk is not initialized or offline. Try right clicking it and clicking "online" to see if that fixes it.
Since there is data on the drive you don't want to format or initialize since that will erase your data.
It could also be the drive letter path was re-assigned & now that HDD is not recognized, because another drive has the same drive letter path. This should be easy to check since all the drives would have a letter path & the drive you are talking about won't have a letter path if this is the case. You would simply assign a letter path to it and that will fix it.
Alternatively you could have a bad SATA cable or simply the drive is beginning to fail.
You can try installing that drive on another PC and if it still doesn't work then you know the drive has failed.

Did you have bit locker on last PC?

it appears the yellow waning in Disk Management means to check the drives SMART score. See -

Thanks for the answers, I solved the problem just right clicking on the disk on disk management and selecting "Import external disks..."
