      In addition to identifying a drive by its drive letter,   
      you can identify a volume by using its volume GUID. This takes the form:   
      
      \\.\Volume{b75e2c83-0000-0000-0000-602f00000000}\Test\Foo.txt   
      \\?\Volume{b75e2c83-0000-0000-0000-602f00000000}\Test\Foo.txt   
      
   I believe it is also possible to call CHKDSK with an identifier   
   similar to that, instead of C: or D: . This can be helpful in cases,   
   where a drive does not have a letter. Note that, while "disktype"   
   utility, returns a "partition GUID", these mountvol identifiers   
   seem to be different and I don't know where those come from.   
      
      chkdsk "\\?\Volume{eb38d03c-29ed-11e2-be65-806e6f6e6963}"   
      
   For example, you can do:   
      
   mountvol   
      
       \\?\Volume{0bd6166a-0836-4041-891c-792df2c72abd}\   
           C:\   
      
       \\?\Volume{c3bc5ab1-c5f0-4dae-838c-751ef868e237}\    <===  This is a   
   hidden partition, equivalent to type 0x27   
           *** NO MOUNT POINTS ***   
      
   Notice, in this example, the trailing backslash should be removed.   
      
   chkdsk \\?\Volume{c3bc5ab1-c5f0-4dae-838c-751ef868e237}   
      
      The type of the file system is NTFS.
