Hi,

I am using knoppix v4.02, and was having this same problem.

I found that the right click gave a drop-down list... select "properties". A window appears... under the 'permissiions' tab, select "read & write" for the appropriate user(s), then select the 'device' tab and remove the tick from the "read only" checkbox.

Not as simple as onemyndseye first suggested. What version are you running onemyndseye?

It took me hours to find the thing under the 'device' tab, and very frustrating hours they were!
