As a relative novice to Knoppix, I've struggled for days to get earlier versions to boot properly off a USB Stick. Having come across 6.01 yesterday, I thought I had at last found an answer.

However, I've had exactly the same problem as you, but having tried your remedy, I get the following when I type in the second line.

Access is denied because the NTFS volume is already opened. The volume maybe already mounted, or another software may use it which could be identified for example by the help of the "fuser" command. You can use force option to avoid this check, but this is not recommended and may lead to date corruption. Mount Failed.

Has anyone any ideas please?
