Same here
I have fought this since Nov 2009. It appears to be a snow leopard thing. I have found that the crash alters volume and directory count on the startup disk and needs repaired. I have tried daisy chaining it and crash still happens. I will call Tascam again today. If anyone finds an answer, please post.
