This may be old news but I talked to Bob at Hoodman, very cool guy -very helpful. I was struggling with restore media errors while using his adapter in my ex3 with transcend 16gig sdhc cards. He explained that there are basically two limitations with the sdhc cards. the inability to overcrank all the way up to 60fps (widely known), and the fact that sdhc is just plain slower than the sxs cards and it takes about 8 seconds for the card/camera to finish writing the file after you hit stop. I was pressing record again before the card was officially ready. If you watch the red light on the card bay on the side, it'll take almost exactly 8 seconds for it to go out after you hit stop. If you never hit record until after this light goes out or turns green (i forget), you'll never get restore media errors. He told me this would be the case wether you use hoodman raw, transcend, or sandisk.. Just a limitation of sdhc. Still a small price to pay to avoid buying $1k SxS cards.. like I said, mabye old news but I struggled with it for a while.
