INTERNAL Drive or EXTERNAL FW Drive?
Best to be capturing and rendering to an internal drive that does NOT also contain the System Folder or FCP program.
THE FOLLOWING COMES FROM THE KEN STONE WEBSITE:
“Over 5,000 years ago Confucius wrote: ‘If you are toiling away, you have changed nothing and FCP heads South on you, [starts behaving in strange ways] then it is time to trash your FCP Preferences.’ ”

A great way to do this is to use “FCP Rescue” a free Apple Script that will Trash the Preferences for you (and restore nearly all of your user settings afterward).
There are versions for FCPro & FCExpress.
