Recently I've had problems when ejecting a Seagate SRD0SP0 USB 2.0 hard drive from my Macbook. It has two partitions, one is my Time Machine backup, and the other is an ExFAT partition for media. There is also a sparse bundle disk image.
When ejecting, diskarbitrationd consumes 100% of one CPU for about 10-15 minutes until finally ejecting. The consoleConsole contains things like...

I've changed the volume names to be more obvious which is which.
I've run Disk First Aid on both partitions. This is OS X 10.8.2 and was cleanly installed a few weeks ago. I have no special software running but Sophos An
Any ideas about what the problem might be or how I might go about diagnosing it?
