    Just bought a 4GB Secure Digital card marked SDHC. I know this is the new standard for SD, but I expected that my iMac, less than one year old, would recognize the chip.

    My older HP Windows machine recognizes the 4GB SDHC card instantly, I can read and write on the Windows Vista machine.

    My iMac does not recognize the chip at all.

    Is this a general problem? Or is it unique to my machine?

    you need a new USB adapter. The, now old, USB readers, will not read the new HDSC cards.

    Make sure you buy a reader that says it's compatible with HDSC memory cards.

    Thanks for the quick response, Joe.

    That was the problem ! ! !

    Going out now to buy a new reader.

    Many thanks . . . again.
