Ok, so I found the UI element that lets me attempt the repair. However, it continually fails its task. I used Process Explorer to look for open handles to the drive in question and found none. I then decided to run CHKDSK manually. An initial pass with the command "chkdsk d:\" reported a bitmap error and suggested a "chkdsk d:\ /scan". I then ran that command and it completed reporting that the file system was clean. No errors. I then set the filesystem to unchecked in Stablebit Scanner. I initiated another file system check and was then again notified of a damaged file system once again. Not sure if I'm missing something here or what.
