I have an EmailXtender 4.81.2031 environment that stores the container files (.emx files) on an extended disk.  DiskXtender 6.3 in turn archives the EX container files to a Centera.  We have recently upgraded all of our storage equipment and are now in the process of decommissioning the Centera's and DiskXtender.  This requires me to move the EX container data to another non-extended disk.  EMC support instructed me to migrate the EX data from the Centera by simply copying the data to the new drive.  After I copied the data and reconfigured EmailXtender to point the new container drive, everything seemed to work OK.

However, after doing some tests via the search console.....several of the emails could not be opened because they could not be found in the newly copied container files.  The EMC support engineer decided to re-copy the suspect containers from the Centera to the new drive, and after doing so everything worked fine.  The thing is.....the suspect .emx files had the exact same size and timestamps as the good files.

Is there a utility of any kind that can check each .emx file and verify whether or not it is corrupt?  I can recopy all the data again, but there is no guarantee that I won't encounter this problem again.  We have over 25k containers.....and I need someway to make sure they all copy over successfully and the data is valid.

Does anyone have any ideas?
