I have a similar issue with mine, I can record and playback video, I can then chop up a large video into smaller sections...but when I try to create a project that uses video from the first drive, then changes to the other drive it fails. Drives pass Flyer Format/Calibrate above the required transfer rates for the highest quality. Unfortunately I don't have another Flyer to swap out....well I do but it doesn't work at all.
I've pulled all my drives currently and haven't had a chance to investigate it more.
