dd, physical devices, Compact flash, Permission denied

Hi,
 

I have a problem restoring a image back to a new CF card.

I am using the last Cygwin on Windows XP. 

I mounted the CF card :
 

mount -s -b //./I: /dev/cflash 

then

I made the image of the card:

dd if=/dev/cflash of=/home/flashcard.img

 

That worked without any problem, but

After that I have put a new formatted CF card

And I want to restore the image file that I made to the new one.
 

dd if=/home/flashcard.img of=/dev/cflash 

And it comes:

dd: opening '/dev/cflash': Permission denied

 

What is the problem?

Can you help me someone?
 

I want just to clone one CF card

 

Best Regards

Kristian Ivanov
