I am having problem with making an image of Windows vista dell laptop. I was trying to make image from Zen work disk and USB flash drive. It's giving me an error message System error: 30. Please help to resolve this issue so i take image of new computer.

I try with /mnt/usb
mkdir /mnt/usb
mount /des/sdb1 /mnt/usb

I like to store this image on Local usb hard disk.

Thank you
