Windows 10 saw 2 disks during installation - but not HDD when installed

[sewerino26]

Hello. Have an question. I have SSD Crucial 525 GB and HDD Toshiba 500GB.
During installing WIndows 10 from pendrive Windows 10 detected my 2 disks. I choose install system to SSD. But when system installed when i go to control panel and check disks,ssd C: was only visible. D: was not visible.
So i just create partition and manage to create D: and its fine.
So its was normal or not? Why it saw both disks during INSTALL,but not when system installed. I just create partition to make D: visible.

As long as you're sure you aren't accidentally creating that partition on the C: drive ya that's fine. Just go into disk management and mount the other drive. This happens sometimes. It's normal-ish.

That's entirely normal. During installation the Windows setup program lists what disks are available, regardless of what state those disks are in. They can be completely blank and still be listed, the installer is just showing you potential installation places. But after installation Windows is really only concerned with volumes, so a blank disk will just be ignored until you correctly partition and format it.
