Hi Andre,
I have just had a very similar incident occur with my H2.
I recorded a performance using the 4 channel setting.
I wanted to hear a little of it immediately following the concert but the unit itself said “no files”.
When I connected it to my Mac, the files were visible in the H2 disk image on my desktop. I dragged them to my desktop and they copied. When retrieving info on the files, my computer acknowledges them and says they are well over a GB each.
They will not play. When a player opens, it merely shows that the length of the recording is 0:00 and plays nothing. But the file itself is well over a GB.
I did not delete the files from the H2 player. But it still doesn’t acknowledge their existence.
Do I need some sort of special plug-in to play it?
Thank you
