Question about Zoom H4 Handy Recorder

1 Answer

Corrupted WAV file will not play or transfer to computer


I use my Zoom H4 to record an audio podcast, and I spent over two hours last night recording, when the batteries ran out of power and the recorder was forced to shut down.

I replaced the batteries and proceeded to finish recording with a new WAV file, assuming that the H4 had managed to save the original file correctly.

Unfortunately, I discovered after recording that the original WAV file, which is nearly two hours long, is corrupted. Windows reports an error when I try to copy and paste the file to my system via the USB connection ("the file is damaged or corrupted..."), and the Zoom itself will not play back the file (it just skips over it to the next file.

When I look at the size of the file in the Zoom menu, it reports the size of the file correctly in terms of megabytes, but it lists the length in minutes as 0:00 (etc.).

Is there some way I can transfer this corrupted file to my computer so that I can investigate it, and maybe -- just maybe -- recover the file? I'm really hoping to save myself the hassle of re-recording my session.

Thanks very much for any tips or help!

    I have the identical issue now from an interview I was doing for my podcast that I did on my zoom h4. Later files are fine but not the one that the batteries died on. I'm continuing to investigate a fix. For long recording I will now always insure I have fresh or fully recharged batteries.

Zoom H4 Battery Problem

I am having the same problem with my Zoom-H2. I have 2 2650 mah rechargeables, and the draw is such that 20-30 minutes of record &/or playback kills the batteries. Last night I just turned the power on and did nothing. 5 hours later the batteries were dead...

This isn't a solution. It is a reaffirmation that you aren't crazy!

File import in 4-track mode impossible

Convert the audio to Mono WAV (16Bit, 44.1KHz). This can be done by using Cubase(Hope you got Cubase LE with Zoom). In an empty project import the audio, then mark the whole track using the Draw tool and then got to File->Export. Here select the above options and export. Import this file into Zoom H4 either by copying directly into the memory card or through connecting the Zoom to computer ( I copy it directly into the memory card's STEREO folder). Now if you import it to any project, it will appear there. You can now use Zoom H4 as a Karaoke device!! Anyway, sad that Zoom H4 doesn't support stereo tracks in the 4Track mode.

You need to upgrade the H4  firmware from Zoom website

Zoom h4 not recognized by computer

Mac OS 10.4 and higher require the Zoom H4 to be upgraded.
Go to and choose the download to version 2.20 that applies to you. The instructions are there, but it is a little tricky. You must download the upgrade to your computer and then transfer it to your Zoom SD card. To do that you need an SD card reader. I used my digital camera. I took the SD card out of the zoom and put it in the digital camera. I Plugged the camera into the computer and when the SD card icon appeared on the desktop I dragged the "System Bin" file from the download to the zoom folder. The rest of their instructions were pretty good. Good Luck.

Zoom h4 Vista recording

Don't know if this is the problem in your case ... but here's what I did:
Note: I have Win XP
Previous to attempting connection between laptop and H4 as an audio interface I updated the H4 firmware to ver2.4 and connected to the laptop successfully as a card reader. From the laptop, I could see files I knew were on the H4 card.
... but when I tried connecting in Audio I/O mode, my laptop didn't know what to make of the H4. There was a USB mass storage driver associated with the H4 - I could see this from the "Device Manager". I "uninstalled" the USB driver associated to that "unknown" USB device. I terminated the audio connection on the H4, then reconnected. !!! It was recognized as "USB Audio Device" in the "Sound, video and game controllers" section of the "Device Manager". Before, it was listed under "Universal Serial Bus controllers" as a generic USB device with a yellow warning highlight indicating there was something wrong.
Hope this helps!

Software problems

Are you using Vista? I've posted another threat here (still no answer), cause I can't get Vista to recognize H4 as Audio I/O. I've also sent a mail to Zoom in Japan. They answered in english thanks god, telling me to upgrade the soft in H4, I can now move files to the computer, but still can't get Vista to recognize H4 as an Audio I/O, I mean, in record devices, Vista shows "camera mic and line in", that's all.
Ok , good bye

Distortion with Zoom H4 as Audio I/O to computer

try using the power pack instead of batteries. Be sure to remove the batteries before using power pack, you can wreck the machine if you do not remove batteries. NEVER use the H4 on power pack while there is batteries inside.

Hi Guys,
I have the same corrupted file, but you can recover it by using the GoldWave software. Just type"Goldwave" in google, follow the link and download the software, install it. From that software open the corrupted file, and then save it as a new copy. ( It will fix the problem when opening the file, where you can see it). They try to play the new saved file, shld be fine.
all the best.
