I've bought a SDHC card 32 GB but Handy Recorder H4 do not recognize the card. I've tried to format it at the pc, but no way, the message is "no card"

This may be or not be a solution, but most times you have to format the SDHC card so that it is recognized by your Korg

It may not be a problem. See if you can perform a facrory reset and start again.

Make sure the batteries are good... some people try to use re-chargeable batteries and because of their lower voltage they cause problems. First thing is to try new batteries.

Here is a link for you:http://www.zoom.co.jp/english/download/software/h4.php Try updating your system software.

Hi. Not sure you still are in need of a solution but since my machine was doing the same thing last night, and I was able to solve it, I thought I'd post anyway.
For my machine, which has a more current OS than yours (mine is 2.20 I believe), I was receiving the same message after transferring material onto the computer. What needed to happen was to reformat the card. If you press "menu", the click on "file" you should have an option to reformat the card. It worked for me and it now works.
Hope that helps!

Are you using the type of card recommended in the manual? There's also an update here that you might like to have:http://www.zoom.co.jp/english/download/software/h4.php

Hello.

Do you havce the manual to the H4? If not, I will provide you with a link to the PDF manual online. In thoroughly scanning thfe manual, there is no general reset function (in the manual, that is). It would be advised to call Zoom (who are very easy to work with) and ask them if there is a factory reset procedure which is not in the manual.

The manual for the H4 is very comprehensive, and there are default settings for many areas of the recorder. You could use this manual to reset your adjustments manually.

Here is the link to the manual:

Thanks for using FixYa

Sounds like it's time you upgrade to a core 2 or better computer.

Contact ZOOM ?

If you are using a Mac running Leopard (Sys 10.5), you need to upgrade the H4  firmware from Zoom website

You will need an external SD card reader.
Good Luck
