Problem with 4 GB and 8 GB card with GF1

[Alan E. Schlesinger]

I have had a strange problem with my GF1 and Sandisk 4 and 8 GB SDHC cards. I have been using several 2 GB Sandisk Ultra II SD cards with the GF1 without problems. I format them in the camera each time I use them and they have worked fine. I recently bought a 4 GB Sandisk Ultra II SDHC card and formatted it in the camera. It worked fine in the camera (can view images in camera), but my computer will not recognize it. I tried several other computers with no luck. Then I put an old 8 GB Sandisk SDHC card (not an Ultra) that I have used for months w/o problem in my Canon G10 (including very recently). I formatted it in the Panasonic. Again, images can be viewed in the camera, but the computers will not recognize it. When I reformatted in the G10, I have the same problem now (cannot be recognized by any computer). I have retried the 2 GB cards and they all work fine. Is it possible that the GF1 is doing something to these 4 GB and 8 GB cards to make them unreadable? If it was only the 4 GB card (that I never used in the G10 before), I would assume it was just a bad card. But, I am afraid it may be something with the camera because my 8 GB card had worked fine before. Any thoughts?

May have just figured out the problem. I recently lost my card reader and started using an old one of my daughters instead. Perhaps the 4 and 8 GB SDHC cards cannot be read by my computer because the card reader is not compatible with SDHC cards? Maybe my 8 GB SDHC card worked in the recent past with my G10 because I was using that newer card reader (that is now lost), and it is not being recognized by the computer now because the card reader is older. Are older card readers not SDHC compatible? Perhaps I should buy a new card reader and try that before assuming that the cards are bad (whether or not the GF1 was responsible)?

I'm thinking your PC's SD card slot can only read SD cards but not SDHC (like my PC).. I use a USB card reader to get over that..

Problem solved!!!! It worked with a newer card reader. Obviously, the older card reader I had just recently started to use (due to the loss of my usual card reader) was not SDHC compatible.

I faced exact similar issue with Lexar 4GB SD. Card was not getting recognized through any laptop's built in card reader. Then I tried external sandisk card reader through USB port and everything is working fine (card regonized, images downloaded) The only other laptop that also recognized the card was Dell mini 9

So I suspect its something to do with the card reader than panasonic or GF1
