Persistent home directory

I tried to create a persistent home directory on a USB-key under Knoppix 3.7. I used the the button ( script) Knoppix > Configure > Create a persistent KNOPPIX Home directory. After that I check the contains of the USB-key. I have a new file on it it seem to be a knoppix.img. I decide to test the persistent home directory by creating a text file in the home directory and I reboot the machine. At the boot prompt I type this "knoppix home=scan". After the boot my text file is not in the home directory but the knoppix.img is already on my USB-key.

What is the problem?

Thank you

So your home partition wasn't on the usb-key when you created the text file?

Try it again and remember to type "knoppix home=scan" or "knoppix home=/dev/sda1" (if you have no other scsi devices) at the boot prompt first.
