Hello,
I'm back with log file. Log contains only situation related to this topic. Before starting new conversion operation I've removed all previous logs.
Regards
EDIT: I've checked worker log file and this information:
[PopulateVolumeProperties] volume \\?\Volume{90f40b30-30cd-11e2-849d-000c29da83b7}\ corresponds to \Device\HarddiskVolumeShadowCopy1 device name.

showed me where the problem is. I've runned diskshadow.exe, and performed delete shadows all operation. Now I can move forward with conversion. Thanks
