I have a usb drive which I would like to put a linux distribution on but it already has some files on it on /dev/sdc1. Using fdisk, I deleted the first partition and wrote the changes. When I printed the table, the first partition was gone.
Then I created a new partition (/dev/sdc1).
However when I wrote these changes to the usb, the old files were still there. I followed these instructions after deleting the first partition http://www.zorge.net/?p=22
Are there any commands in fdisk (I'm trying to get comfortable in fdisk, so no gparted for me) to completely wipe out all the information on a drive?
