So Why Doesn't W10 See this drive ?

This may of just happened, but I'm not sure. I've been forcing myself to use W10 "System->Storage" to clean up my system. But I noticed a drive that is seen in "Disk Management", "Explorer" (and I can access it) but does not show in the new "System->Storage" display ? Some thoughts are that this is a really old drive (SATA I). Is slow but it still does the job. If anybody has an idea why this is happening, I would appreciate a response. Took some screen shots below:

Run Diskpart from an admin command prompt then automount /enable then reboot. Does that fix it?

So you have seen this problem before and running DiskPart fixed it ? Any idea how "Automount" got disabled ?

Yes and no

Hmm Just thinking about "Automount". My PC case has 6 external drive bays that can support removable drives. I just recently (in the last 4 months), change my configuration and I changed windows and made 4 of the drive bays removable. But when I tried to make that old Sata I drive removable, windows would not let me do it. After some research, I discovered that Sata I drives didn't have the capability and I just left it alone.

OK we I will fix it now. Thanks for your help

@Steve C I followed your directions, but it hasn't solved the issue. The drive still doesn't display in the System->Storage settings area.
