Have you found a solution to the crashing? I am also using using eSATA over thunderbolt with a new macbook pro and 10.8.3. Also Qio Sonnet readers. My cards are 128 GB with Canon 1DC footage. When I copy one card it usually, but not always, makes it through. When I copy two cards, either started one at a time or at the same time, it almost always crashes. Super frustrating! Not happening, at least not as much, with SxS cards over thunderbolt.
I had very little trouble on our last shoot. The differences were minimal. Here’s what changed. I went from a Lexar USB 3 reader to the Sonnet Qios. I put an OWC Raid in as one of the two esata locations. The other is the same Voyager toaster I was using last time. Otherwise, I don’t think I’ve changed anything, but I can’t see how these could have done it.
I do believe we had one bad chip that was hanging up over and over, even just in the finder. We’ve taken that out of circulation but I wonder if it could have had lasting impacts in some sort of bit-karma world within.
Thoughts?
