Yes and no. I concluded that the corruption was due to the ExpressCard/34 eSATA adapter that I was using. When I did the same processes via FW800 I had no corruption problems. I also noticed corrupt files in some photos I had transferred via Expresscard34/eSATA. Here’s a link to the adapter I was using:

I contacted OWC about it and they sent me a new adapter, though, I haven’t had the time or desire to try it again.
Hope that helps.
