I have another post WRT Ghost 15, but this may be a separate issue: ever since using Ghost 15 I am experiencing issues with what I call lost partitions-- the letter assignment is lost and cannot be seen under XP Explorer or Ghost 15, but these HUPs can be seen by XP Disk Management (XPDM). The only right-click option under XPDM is to delete partition-- I don't want to do that because, in my limited experience with Ghost 15, I can still back-up these HUPs to another drive, then restore them... usually Also, there is no explanation for a "full VSS backup" under Advanced Options under One Time Backup Wizard-- where's the documentation?
