EDIT: FINALLY, found a RAW file of similar size and pulled the HEX values out of it.. thank goodness I finally retrieved this footage!

--------
I am getting the "ain't a lv_rec RAW file" error on one of my joined RAW files... all other RAW files are working. I don't know what went wrong :(
Is there any way to "unjoin" the smaller pieces or otherwise save this footage? :\ (I deleted the individual RAW parts (.RAW002, .RAW003, .RAW00x...)
Thanks so much.
