I purchased two Toshiba high speed (class 4) 4gb SDHC cards. Formatted them in the K10D and they work fine.

My HP Laptop inbuilt card reader won't read the new cards, nor will my USB external card reader.

Anyone know if there is a USB driver or SD card driver that can allow me to read these new SDHC cards?

I can access the images and download to the laptop by connecting the camera direct to the laptop.

This is a bit late, but Sandisk currently bundle a reader with their SDHC cards because of these compatabilty issues.

I recently bought two 2G cards rather than 4G because of these issues as my computer's card reader won't look at SDHC cards.

You might want to check with HP and your card reader manufacturer to see if there are firmware updates which will allow the reading of SDHC Cards.



My sandisk "5 in 1" reader would not read the SDHC card. I went to the sandisk site and downloaded the firmware update for the reader and now it works perfectly.



Don't just run out and buy a new one before you check for the updates.

Hi Crash,

how long do you think it will take to download a full 4 gig card? Doesn't sound

like it's going to be fun! Good luck with the firmware updates.:sad:

I had this problem when I bought my first SDHC card.

Searched around, and at the time the only card reader I could find was made by Kingston, but at around £7 delivered I bought it.

Something to bear in mind if you have to buy a new card reader, is that they are very cheap these days.

Often you can buy a SDHC reader at places like RadioShack for considerably less than $20. I think I paid $9.

Yeah, I noticed the cheap SDHC card readers on line last night, some were as low as AU$6.

No firmware updates for my card reader or HP Laptop!!!!! I discovered it is all to do with drivers and at seems that noone is interested in making new drivers for older hardware, they want you to buy the new hardware.

Looks like I will have to fork out for a new card reader, at least they are not expensive. I just enjoyed the ease fo the built in card reader on my laptop.

4Gig = 817 images on the K10D....yep, long download times I suspect.

once you get all the data off your sdhc cards, try reformatting them in fat16 using 64k clusters. you'll have to do it from a command prompt as it does not work from the gui. the difference from sdhc and sd is the file system, sdhc being fat32 to allow the larger memory cards. also if youget it to work, that means the cards will be compatible with your standard sd card readers and they will probably be faster to transfer data using the 64kb cluster size. the only part i am unsure of is if you need the sdhc card reader to reformat them or if the standard card reader will be enough to at least reformat them.

enter--> format /? at the command prompt for help on how to get it to work.
