I'm booting from SD card and would like to make a back up of the entire thing on my computer in case anything gets corrupted.

I'm using Windows XP.

Thanks.

Just use
Code:
dd if=/dev/mmcblk1 of=/home/user/MyDocs/some_image_part_one count=2000000 bs=1024
dd if=/dev/mmcblk1 of=/home/user/MyDocs/some_image_part_two seek=2000000 bs=1024
Copy the two files to your XP box.

EDIT: The above code are just two line, do not know why the first code line is spread about those two lines.

But you need to "umount" before the dd to prevent corruptions? Plus I think it's better to shut down the N900 properly, remove the microSD card out and copy it from a reader. Just what tool to use on Windows XP is the question as I myself use linux and would use the "dd" tool on it.
