about 1 week ago, i noted one of the hard drives revving up for no apparant reason. the free space on drive c is at a minimum. tonight, i decided to delete some things, and try to defragment the c drive. to my surprise, i found a new drive was listed on the defrag window. just for the heck of it, i tried to defrag it, but, it did not scan or defrag. the name of the "drive" is : \\?\volume[c1d36960-05c2... can anyone tell me what this could be, and why it is there?? Thanks much in advance.
