I use 10.6.8 and try to write from within FCP X and Toast 11 to a Blu-Ray disk (lucky rewritable) It will not work from within FCP X and Toast gives an error after 2/3 writing. The error is: The drive reported an error: Sense Key - HARDWARE ERROR Sense Code = 0x44 INTERNAL TARGET FAILURE I tried an eSata cable and Firewire. And it worked before months ago. Paul Moortgat
