why cant copy file (about 1.7GB) from SDHC card(only in 4GB) ??

Hi all
I meet a hard issue in SDHC 4GB card.
My platform is Wince 5.0 and update patch from 2007 to 200803.
The issue is when I copy a file (about 1.7GB) from SDHC card to SDHC card (
itself ,such as from A directory to B directory) or to flash disk(in the same
device),it alway fail.
Other size is ok(just smaller than 1.7GB).
And the same behavior in 8GB card, the file copy(about 1.7GB) is successful.
I dont know what happened.. Would someone help me..?
Thank a lot....

Did you include the sdbus2 bus driver in your OS (IMGSDBUS2=1)? Is the card
mounted as a 4GB card?
When it is failing do you have some debug code which indicates what is going
wrong?

Yes , my SD drvier support SDHC, that my device can identify SDHC card( >
4GB), and I can see the capacity just as the card really is.

Oke your SD driver support it but did you include SDBUS2? ie: did you set
the variable IMGSDBUS2=1?

And what about the error message (if any) Did you enable more debug zones,
more logging, could you provide us more information then just "it don't
work"?
