Since updating to the latest SD I suddenly have problems with the copy freezing on an I/O error. Here's the last few lines from the log file:

This has happened with both of my 80 GB external FW drives, one is a wall-powered standard-sized drive, and the other one is a bus-powered unit with a laptop drive. Both worked flawlessly with SD before. The failure is always as above, with the choking point always being an iTunes file. I managed to get the larger drive to complete a backup by deleting the offending file, but the small drive still chokes each time. An even bigger problem is the way that SD refuses to quit gracefully - I have to simply unplug the FireWire cable, which of course outrages the Finder and causes who-knows-what kind of corruption. Where to go from here?
