I have 2 drives in my computer: an SSD and a HDD (Seagate Barracuda Green ST2000DL003). The HDD was assigned the drive letter G. If I go into Explorer and type G: in the address bar, I can see all the files and folders on the disk.
But if I open Explorer and go to Computer, it only shows the SSD. How can I make both drives appear in Computer?
I am using 64-bit Windows 10.
Edit: Picture of this.

Edit2: So I seem to have found a way to get it to show. There is a partition called "Reserved by system" - which belongs to the SSD. It kind of bothered me seeing it under My Computer so I went into disk manager and removed its drive letter. Giving it a drive letter again seems to have brought back to HDD aswell..

Is there a non-zeroNoDrivesentry? Also try the same path underHKEY_LOCAL_MACHINE. – Ben N Jul 31 '15 at 19:10chkdsk /f g:to check the drive for errors. If that doesn't help, try changing the drive's letter by right-clicking its entry in Disk Management, choosing "Change Drive Letter and Paths", and pressing the Change button. – Ben N Jul 31 '15 at 19:21
