Question about MediaID, GlobalCatalog, and GlobalCatalogBackup fil

So far I am trying to implement a backup application in Windows Vista like
CompletePC backup utility. However, I still cannot figure out how to create
MediaID, GlobalCatalog, and GlobalCatalogBackup files in WindowsImageBackup
directory, and how CompletePC Restore locating VHD file. Therefore, is anyone
known where can download useful documents and give me some suggestions about
it? Is any program can open with GlobalCatalog, and GlobalCatalogBackup files?

The data of the MediaId is as follows,
90 33 06 B9 7D AD 25 46 86 DF 50 A2 0C AD B4 77

Is anyone know how to obtain or generate this number from Windows Vista?

From my understanding, I think MediaID is a unique serial number and media
types are including: Flash, Hard Drives, CD, and DVD. meanwhile, I tried to
find possible related to MediaId in SDK and DDK. Finally, I got one of the
result was kind of related to MEDIA_ID which was AACS_MEDIA_ID structure in
Storage Devices of the Windows Driver Kit. The detail of the structure is as
follows,

typedef _AACS_MEDIA_ID {
UCHAR MediaID[16];
UCHAR MAC[16];
} AACS_MEDIA_ID, *PAACS_MEDIA_ID;

I am not sure, is it the value in the MediaId File? or is MediaId file
containing VDS device serial number? or is it id in VDS_DISK_PROP structure?
