I originally posted: "I bought the same card at Clubit.com. It is the slower one, and so far, no problems."
Now, I have nothing but problems with this card. I do have the latest firmware update (1.20) for the R-09.
The card is seen by the R-09, it formats, and shows 3.75GB available. I record at 24 bit, everything goes as normal as when I was using my 2GB card. The card is not seen by the computer, either loading it from the R-09, or from various USB 2.0 SD Card readers.
The card works flawlessly when formatted from the computer and used in those same SD Card reader/writers as a device to write files to and from the computer, but to use it in the R-09, it has to be formatted in the device, and then it doesn't work for me. I'm going back to my 2GB card.
