There is a option inn fdisk to clear all partitions from the disk which will leave you in a position to partition the disk from scratch. parted and/or partitionmagic are not needed. I assume that your disk will be something like /dev/sda so you would run the command : fdisk /dev/sda, and away you go. -- ======================================================================= Interfere?
