In w7 I made a "d" partion and used w7 save image to it every month worked just fine.

now the problem with w8 the "c" drive was 902gb just sort of 1tb so went to disk mnagement but it would only let me shrink the "c" to 457gb still very large would not let me shrink it anymore no idea why? so did that and set up a "d" partition with the remaining 449gb [healthy primary]. then a defrag and to the w7 image tool which auto selects the "D" for the backup and lists [EFI partition, [C][system], windows RE tools [system] to be backed up. all fine so far, but when i click start backup i get the following error warning "there is not enough disk space to create the volume shadow copy on the storage location. make sure that, for all volumes to be backed up, the minimum required disk space for shadow copy creation is available. This applies to both the backup storage destination and volume included in the backup. minimum requirement for volumes less that 500mg the minimum is 50mg of free space. recommended at least 1gb of free space on each volume if the volume size is more than 1gb [0x80780119]" my "C" drive is still 86% free space i can not shrink it anymore for unknown reason and totaly lost on how to sort this saga out, never had this in w7.

anyone got the patience to grasp all this anh help out please.
