Kodak DX6490 and SD card Problem

Archived from groups: alt.comp.periphs.dcameras (More info?)

I'm having a strange problem with my DX6490 and SD card. When I
manually save files (pictures) to the SD card from my hard drive via a
USB card reader connected to my computer, I can read the pictures off
the SD card at high transfer rate. When I attempt to read pictures
saved to the card by the camera with the card reader, it is very, very
slow. And Windows places errors in the event log as follows:

"An error was detected on device \Device\Harddisk5\D during a paging
operation."

Remember, this error only occurs for files written to the SD card by
the camera (i.e., when a picture is taken). It does not occur for
files which I transferred to the card from my hard drive. It's like
the camera is writing bad data to the card.

For example, a 1M picture takes about 12 seconds to display if it was
placed on the card by the camera. If I save a 1M picture from my hard
drive to the card, it takes about 1 second to display.

Any suggestion?
