After installing windows 10 my 2tb hdd doesn't show up any more!!!!

[Lightning6446]

Ok so I'm gonna try to make it short basically I had windows 10 on a very slow hdd that was 3200rpm and 350 gb and a 500gb drive and a 2tb drive so I was basically sick of how slow that hard drive was and how slow windows was so I bought a 256gb ssd and I installes windows 10 on it but for some reason the 2tb drive no longer shows up in file explorer it's in disk manager but that's about it and I had it partition to 2 partitions 1tb each but it shows as a storage pool of 2tb now I was worried so I entered in bios and started playing alittle bit and accidentally ended up booting into my old windows 10 drive since I didn't pull it out and to my surprise the drive works perfectly boot back to ssd nope doesn't work and so on so now I'm faced with the choice of either staying at the slow ass hard drive with all of my data or be on the ssd and format the 2tb hdd which I don't even know how because I can't even do anything to it since when I right click on it in disk management everything is greyed out except for help and I really don't want to format it I have over 1500gb worth of files on it it would really suck if there was no choice please any suggestions btw I've tried damn near everything easeus,diskpart,etc and nothing works!!!

since you did put the os on ssd both with it only as first boot device then after system would hvae done a full boot you could plug in the hdd power off fisrt then restart since it still read boot ini from hdd .

It may not have a drive letter assigned to it. If it doesn't it will not show up in file explorer.

You can assign a drive letter to it in disk management.
