Hi Peter, I've been doing some reading. It looks like you can only use the SDHC logo and speed class things if you are a member of the SD card association www.sdcard.org
The Ridata card is SD V2.0 compliant, which is what SDHC is. I know that the 4 gig Ridata didn't work in the K100D until after I did the firmware upgrade. Then it did. I will check the locally available card readers for SD V2.0 compliance and see if I find one that will work. -- Leon http://www.bluering.org.au http://www.bluering.org.au/leon Peter Loveday wrote: >> I have 2 4 gig Ridata 150X cards for the K10D and they work fine.
