I'm curious as to why a blank (as in formatted) drive would show it has Movable files and folders or even Unmovable when I run the Windows 7 defrag tool on the drive.

C:\windows\system32>defrag E: /H /A /V

                Total MFT fragments         = 2

        Note: File fragments larger than 64MB are not included in the fragmentation statistics.

        You do not need to defragment this volume.

dir /a E:\ reveals no files or folders. attrib e:\ does the same –  Rodney Jul 30 '13 at 14:56
    
chkdsk /f e: shows no errors nor change. –  Rodney Jul 30 '13 at 15:56

Most of these are special files, which hold information on the partition itself. For example, $Bitmap is the successor of the FAT found in old FAT partitions. It keeps a record on the usage of space on the partition. There are more than $Bitmap, for example $Journal, but still I think 35 files are more than just these internal files. System Restore could be to blame, it puts some files in \SystemVolumeInformation. EDIT: $Mft counts too.
