I have transferred around ten 50gb XDCAM discs to an external drive connected to my laptop. I did not use the XDCAM utility rather I used a program called Vice Versa. I use VV all the time to move large video files because I trust it to check that the files match.
Anyway, the files on the external drive show high 70's to 80's GB for the discs. Checking the folders of one disc I see around 34gb under the Clip folder and I also see about the 35gb under the PROAV folder.
The ProAV folder is usually hidden and contains all the raw, non-interleaved video and audio data. When you copy the whole disc including ProAV you are effectively copying the data twice. You can disable the ProAV folder display in the XDCAM Drive Utility. If you are manually copying using your OS or a 3rd party utility you can leave out the ProAV folder. The only exception would be if you are doing a mixed res workflow in Avid (Proxy video with high res audio), in which case you should preserve ProAV in your copies/archives.
