c++ - How do I get the upper half of the Volume id in Windows? -


this link @ ubuntu says "the option --new-half-serial changes upper part of serial number, keeping lower part used windows unchanged."

that suggests upper half of volume id exists on disk, there way @ in windows? (getvolumeinformation returns lower half). ubuntu shows entire 64-bit value blkid.

notes:

"this not volume uuid used windows locate files have been moved volume."

this refers volume uuid, not volume id talking here. volume uuid of form: \\.\volume{7e899cb7-0079-11e1-bc4e-002219f6e9d9}

i think want have @ 

ntfs_volume_data_buffer

structure, , deviceio command:

fsctl_get_ntfs_volume_data

and function deviceiocontrol(). think find looking in there. first member of nfts_volume_data_buffer defined large_integer, typedef to:

typedef union _large_integer {     struct {         dword lowpart;         long highpart;     };     struct {         dword lowpart;         long highpart;     } u;     longlong quadpart; } large_integer;

let me know if helps @ all...
