If this is a new drive, then it may have a partition on it from the factory. If so, it is probably a vfat partition, and it may not be the entire drive. You will need to unmount the drive, and then use fdisk to change the partition type to type 83, and then run mke2fs on it to create a file ext3 file system. If the partition is not the entire drive, delete the current partition, and create a new one. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
