When searching for files on the F and L drives, it works properly and I am given a result. However, when I search on the C drive, it returns no results, ever. So I checked my indexing settings, made sure the C drive was selected and rebuilt the index. Still, searches turned no results. I did this multiple times. I also tried restarting the Windows Search service and changing policies in the Group Policy editor to no avail. Then I noticed something when deselecting the C drive in the indexing menu: When the C drive is deselected in the upper menu ("Change selected locations") the F drive disappears from the lower menu ("Summary of selected locations") even though the F drive is still selected in the upper menu. Also, when the F drive is deselected in the upper menu but C is selected, F still appears in the lower menu. When both C and F are deselected, F doesn't appear in the lower menu. It seems like drives C and F are connected somehow. I still have yet to find a way to index on my C drive.
