Sorry for the slow reply. I didn’t get hold of Karl unfortunately.
I’ve been to so many data recovery companies now it’s getting ridiculous. Zoom UK haven’t been able to help either. They said they would try and put me in contact with Zoom Japan but no dice yet. Zoom UK seemed to think this was a very unusual situation, I pointed out that it’s a common flaw in their systems. For me the unit didn’t loose power, I actually switched the unit off at the end of the recording and it shut down without saving the files properly. This really shouldn’t be physically possible if the files are not written, the unit should either warn you or just take longer to switch off.
Of about 100 different data recovery companies only one seems to actually understand the issue. They are based here in the UK and are called Ontrack.
They haven’t been successful yet but they are on the right path. I basically gave them all of the information on this thread and also did some successful recordings for reference.
We are up to this stage: “It’s more like I have a long audio that’s missing certain intervals, So can hear for 3 seconds then drops for 2 etc, so just need to find out the length in bytes before the next channel is stored, as on disk it’s not sequential.”
If successful I will post here. Not cheap either, £250. However I really, really need this audio so will keep going no matter what. @ Karl Chelette, there are a few of us out here who would gladly pay for you to work your magic!
