Dear Michael and Silviu, thank you for your help!! - I managed to remove the partition and now there are only Windows XP and Ubuntu 10.04 (and swap) left, both systems now have about 40 GB. I also tried df -h and everything seems to be alright: Dateisystem Größe Benut Verf Ben% Eingehängt auf /dev/sda6 37G 5,4G 30G 16% / none 240M 280K 240M 1% /dev none 245M 312K 244M 1% /dev/shm none 245M 84K 245M 1% /var/run none 245M 0 245M 0% /var/lock none 245M 0 245M 0% /lib/init/rw I also downloaded feeds the way you explained it and FAST still fails (but FIRST is alright now): Starting SIENAX (including testing BET and FLIRT and FAST) at Mo 16.
