How do you format a Sandisk 4GB micro sdhc card so it can be used in a nokia 3109C?

Is it an SD card or a microSD card? If it's a 4GB (or larger) card then it's neither, but instead an SDHC or a microSDHC.

If the card is an SDHC/microSDHC then your card reader may be only SD-compatible. If this is the case then you can buy an SDHC-compatible card reader and use that. Alternatively, if you want to use this card with some other device, such as a camera or a phone, format the card in that device instead of in your computer.

1. Be sure that the device you are using the 4GB micro SDHC card for,
is able to use this type (HC=High Capacity) of memory.
2. Check the memory card is working well on a notebook / pc with an adaptor
and/or a SD-cardreader.
3. Format the memory card and re-check.

ya.. surely!

I would try to reformat the sd card first and if the problem continues go exchange it.

Your memory card reader lacks SDHC compatibility. You must either update your pc card reader to one which is compliant with SDHC or use a cheap external card reader to do the job.

SD and SDHC cards look the same and fit the same slots, but they have significant technical differences which older readers cannot handle.

Your camera was designed before the SDHC format came out. Sorry, your camera can only use standard SD cards, those usually 2GB or less. An SDHC card will not be recognized properly by your camera. If you really want to use a 4GB card, do a Google search for SD and "non hc", with the non hc in quotes. Believe that Transcend makes one.

you should do the formating thru your mobile phone so that the configuration may match to your cellular phone.

Hello,

Certain cameras will not recognize an SD card because it is SDHC. The format was created after the camera. Camera vendors do issue firmeware updates.

Hope it helps.

Took it to Jessops by the process of elimination "Integral reader faulty."
What a waste of many hours !

How long did you use it in the g6? If it wasn't for long I would say it sounds like you got either a bad stick or a fake stick. Fake sticks are easily passed as the real thing. They even come in the perfect oem packages. Will your Nokia still recognize it? Why didn't your Nokia offer to format it for you I wonder? Go to the http://support.microsoft.com/kb/923293 and apply the XP hotfix if you are indeed running XP. Hope that helps.
