Installing firmware on a new disk

Can anybody Help???
I have successfully partitioned my hard drive using the instructions from this website and my windows computer booted up into gparted.
http://lacie.nas-central.org/wiki/Insta ... space_2%29.
but for the life of me. I cannot copy any of the sdan.gz files into the partitions.
I am using the following command.
gzip -dc /dev/sdf/to/sda6.gz | dd of=/dev/sdb6 (/dev/sdf is my usb pen containing the .gz files)
Every time I press enter, I am told /dev/sdf/to/sda6.gz : not a directory.
What have I forgotten to do?? Can anyone help me.
Many thanks
Simon
