F) cause / Ursache:

Cause the VSC VSS issues:

volsnap.sys not bound on disk
Die neue Festplatte hat eine andere Signatur.
Die alte Signature ist jedoch noch im folgenden Schlüssel gespeichert:
New DISK, new Signature.       old Signature is currently stored within
SYSTEM\ControlSet00x\Enum\STORAGE\Volume\1&30a96598&0&>>Signaturexxxxx<<Offset13873BA800Length86AB65800)

G) How to fix A) - E):

doing:

Delete current SubRegKey: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Enum\STORAGE\Volume
Note: only offline! this is a long way...
better than ...
A) Speed Fix / schnelle Lösung
write new disk signatur online with MbrFix.exe  () 
mbrfix /drive 0 readsignature >> read the current signature from MBR
mbrfix /drive 0 writesignature 12345678 >> writes an new signatur into MBR
restart
Windows detect new hdd, install drivers and write a new subkey within "HKLM\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\" 
restart, done!
B) the long way:
Delete the SubRegKeys below the current Key "HKLM\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\"
@'*#!§? :-)
- customer changed hardware config (disk to raid)
RESULT: 
- backup did not work after hardware change
CAUSE: 
- volsnap.sys not correctly bound to new disk (nt!_DEVICE_NODE.ServiceName 
damaged)
RESOLUTION:
--- volsnap.sys not bound to volume
- in VSS trace:

--- solution for volsnap.sys not bound to volume
delete keys below HKLM\system\currentcontrolset\enum\storage\volume\ .. 
this step ensured, that volsnap.sys is properly bound to the volumes again (solved problem with the netnode)
detailed steps for the key deletion: 
A) english B) deutsch
A) english
Action plan:
1) Run WinPE, BartPE, ERDCommander, Parallelinstallation, Parallelsystem
2) start regedit
3) Regedit-> select "HKEY_USERS" -> click Menu "File" -> select "Load Hive"
load the SYSTEM Hive (e.g. C:\WINDOWS\system32\config\ File: "system")
give one name for the loaded hive: "TEST"
4) view on 
"HKEY_USERS\TEST\SYSTEM\Select\"    Value="Current" 
This Value point to the current ControlSet: "ControlSet001" or "ControlSet00x" or "ControlSet00y"
5) now go to the specified Current ControlSet00x: 
"HKEY_USERS\TEST\SYSTEM\ControlSet00x\" within the loaded hive 
and expand to:
"\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\"
and delete all subkeys below \SYSTEM\ControlSet002\Enum\STORAGE\Volume\
(e.g. "HKEY_USERS\TEST\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\1&30a96598&0&Signature12345678Offset13873BA800Length86AB600)"
6) unload the hive (Regedit->File->Unload Hive)
7) shutdown und boot original system
8) Windows detect new vol, install drivers and write the new keys > reboot and ready
B) deutsch
Löschen der SubRegKeys unterhalb des aktuellen
 "HKLM\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\"
1) Starte Win_PE usw.
2) regedit starten
3) Regedit-> markieren von "HKEY_USERS" -> Klick Menü "Datei" -> "Struktur laden..."
gehe zu "SYSTEM" (z.B. %SystemRoot%\system32\config\    Datei: "system")
jetzt einen Namen für die zu ladende Struktur vergeben: "TEST"
4) unter 
HKEY_USERS\TEST\SYSTEM\Select\ mit dem WERT="Current" 
steht der Verweis, welcher ControlSet00x der Aktuelle ist.
5) gehe zum aktuellen "HKEY_USERS\TEST\SYSTEM\ControlSet00x",
navigiere bis zum Schlüssel "\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\"
und lösche alle Schlüssel innerhalb von "\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\"
(z.B. HKEY_USERS\TEST\SYSTEM\ControlSet00x\Enum\STORAGE\Volume\1&30a96598&0&Signature35633562Offset13873BA800Length86AB65800)
6) Datei > "Struktur entladen.."
7) shutdown Win_PE, danach das originale System booten
8) Windows erkennt eine neue Festplatte und schreibt die Schlüssel neu > reboot und fertig
