If there is no answer to your question in about 5 hours, I can try this when I get home. But even if Sony states the use of SDHC-Cards is ok, it could be possible that there is a limitation of size for the cards. Most "older" devices could handle up to 4GB and everything beyond was not properly recognized. Now the only thing I don't know is if Sony utilizes an "old" or a newer card reader in the 600.
Haven't tried 16GB, but my SanDisk 8GB is working without problems.
