So, had my first disaster with the R44, though it was in part user error...
Pretty sure I had it set running 4 channels by mistake, which left me with less battery life than expected. So I had to do a mid-set battery change, and I thought at worst I only missed a minute or so.
Unfortunately, it seems that the first ~hour or so was lost when the battery ran out. The files are still there, and from a memory standpoint it looks like they're there - but there's nothing on them.
Regarding the files, any thoughts?
