|Assuming D and E are partitions on your HDD, have you enabled display/view of all files?|
Try this. In Explorer, Tools, Folder Options, View, Check boxes Display the full patch in the title bar, Show hidden files, folders, and drive. Uncheck Hide empty drive in the Computer folder, Hide extensions for known file types, and Hide protected operating system files. Click OK.
See what comes up.
Also, run chkdsk on each partition.
