I have just purchased a Canon digitalcamera. I have an 8GB HP SD High
Capacity memory card that I have used but with some problems. Like
the 32MB card that came with the camera, the 8 GB memory card is
formatted in RAW.

What's RAW? SDHC is FAT32.
When I remove the 8 GB SDHC card from the camera and put it into my 3
year old laptop, the card is recognized in but not any files on the
disk. In Explorer there is a Removable SD/MMC drive assignment, but
when I click on the drive, I receive a message that the drive is not
accessible and that the network resource type is not correct. When I
check Properties, it shows 0 bytes!! Yet, when I put the card in a
USB receiver and look at it in Explorer, then the card is recognized
as 8 GB and the picture files are shown, as well as the appropriate
directories..! I am trying to figure if it is an issue with the
operating system, the SD HC memory card, or the computer SD/MMC slot.

Does anyone have any info?
Thats a very common result when the laptop card reader
cant handle cards bigger than it was designed to handle.


Hmmmm.... So how does one determine how large a card an internal card
reader can read?

SD/MMC is not the same as SDHC, though an SDHC enabled device can work
with SD/MMC, see your camera manual.

Grant.
RAW, as I understand it, is the format for camera images (raw image
data). The SD/MMC designation is the designation of the SD/MMC socket
and it is how the socket/"drive" shows up in Explorer.

So how does SDHC differ from SD? If there is a difference, then perhaps
I can solve this by just purchasing an SD memory card of the same size,
which would be fine with me.

The Canon manual says I can use SD, SDHC cards, and MMC cards so that
would imply that the problem is either in the limitations, if any, of my
SD/MMC socket or in the OS. Does anyone know if there are new drivers
needed to read/recognize an SDHC card in Windows XP?

Here is what the manual says about memory:
