Sorry for the delay, for 2 days, I was not able to reply to this thread
I really think that this is going to need to go to the Response center, because the number of corrupted Data Calog files is increasing
IN this particular instance, each data catalog is shown with a mediaID, for example
Medium ID: 0c64320a:539f06c7:0cf4:0138
ERROR: Cannot open file C:/ProgramData/OmniBack/db40/dcbf02/0c64320a_539f06c7_0cf4_0138_539F06CF.dat
I doubt if you can get useful information from this media, but run the command
omnimm -list_media 0c64320a:539f06c7:0cf4:0138 -detail
omnimm -media_info 0c64320a:539f06c7:0cf4:0138 -detail
If there is no error, you can export the media, and import it back in, but, if you get another 'Cannot open File' error, just export it out of the IDB
omnimm -export 0c64320a:539f06c7:0cf4:0138
Would you run these commands, output to a 'text' file and attach to this thread
omnidbutil -info > info.txt
omnidbutil -extendinfo > extinfo.txt
