I have been using the Zoom H4N for 6 months now and recently one file has been showing up with no data on it at all.


I even tried putting the card back into the device to see if maybe it was playable on there and it comes up as invalid file.

I always have fresh batteries in my zoom, I have heard that if you are recording on the zoom and your battery dies, whatever you were recording at that moment will not save. In the cases of the two corrupt files I have this has not been the case. I either have my zoom plugged into AC or I never let the batteries get down to 1 bar.
This scares me big time and makes me doubt wether or not the file im recording will be there when im done. I am in the process of contacting Zoom about this problem Im not sure if it is a memory card issue or the device itself but for the time being I do not feel safe. I have heard others having the same problem and switching devices all together. I have heard the Tascam recording device is where they are going.
