The problem is:
2014-11-20T16:51:33.538+05:30 [10956 warning 'Default'] Failed to get capacity for \\.\PhysicalDrive0: error opening disk device: The process cannot access the file because it is being used by another process (32)
As first step try with Local Administrator, if fails with same error you should find which process gets exclusive access to disk, it this is Pointsec... you should try to uninstall the encryption software and then try again.
