So I've been putting my AVCHD's on my little 8gb 5 dollar USB 2.0 flash drive and playing them without any problems. I needed a bigger drive for some of my larger videos so I bought a Corsair 64gb USB 3.0 flash drive. Now with the same files that ran PERFECT on my 8gb USB 2.0 drive, they will play for a couple seconds and then sound cuts out and video is choppy like it's a slide show. I thought it might be the cluster size because it's default cluster size is 32512 or something like that so I backed it down to good old 4096 (which is the same cluster size as my cheap 8gb USB 2.0 drive). I know that should be slower but I thought I'd try it anyway and the results are the same. My 64gb drive is a high quality drive and I'm baffled as to what to try next... Any ideas would be greatly appreciated (other than buying another device that is).
