Hi
I'm not sure what's going on...
I'll insert your image here in hopes that you will get something more helpful from someone else more knowledgeable about hardware.
I see 2 physical hard drives, drive 0, and drive 1.
Drive 0 that has your OS on it, has a capacity of only 119.24 Gigabytes, and Disk 1 has a capacity of only 3.64 Gigabytes.
Can you tell us what type of drive the one labeled "disk 1 exchangeable" actually is?
What physical drive you expect to see the other drives on, what did the configuration look like before you installed Windows 10?
How big a drive was it?

One of the other people here should be able to give you some help.
