Cant copy files to harddrive

in topic http://www.knoppix.net/forum/viewtopic.php?t=18873 i refered to another problem about my drives. one is a 20G maxtor (master) adn a 40G seagate (slave) when i try to copy files from a cdrom, create a new folder on the slave drive, or do anything of the like, konqueror gives me an message that says "access denied to /folder" what am i doing wrong? how can i copy files onto the slave drive. the only folder i see on that drive is "lost&found"

thx again
