Today when going into Disk Defrag, within windows 8.1, I see listed as the last disk a strange volume with now disk drive assigned. It has a lot of letters and numbers after it. It does not show up anywhere else on the computer. I have defrag many times before and this was not listed. No changes have been made to the computer except for the Windows 8.1 update. Any idea what this is and how to get rid of it in disk defrag. Oh, it also indicates that it is 25% fragmented but when you click to defrag, or whatever its called now in windows 8.1, it does nothing. All the other drives defrag correctly.
Any help is appreciated!
Thanks in advance
