dban-2.2.8_i586.isofrom Sourceforge. This version had more chances actually to work.
Note: DBan seems dead project from 2015, and most likely due to modern technologies like UEFI and SecureBoot that allows only signed software to load makes DBAN not working. eg. error
dban can't open /proc/cmdline
sudo add-apt-repository ppa:gezakovacs/ppa sudo apt-get update sudo apt-get install unetbootin
Plug USB drive and get it formatted
$ df -h ... /dev/sda1 1.9G 39M 1.9G 3% /media/joe/FILES /dev/sdc1 15G 1.9G 13G 13% /media/joe/UBUNTU 18_0 sudo umount /dev/sdc1 sudo mkfs.vfat -I /dev/sdc1 -n 'Ubuntu20' # option 1 sudo mkfs.exfat /dev/sdc1 -n 'Ubuntu20' # option 2 mkexfatfs 1.2.8 Creating... done. Flushing... done. File system created successfully. # | -I forces mkfs.fat to work correctly allowing to create a filesystem across the entire device # | -n (optional) -n VOLUME-NAME, sets the volume name (label) of the filesystem
Install DBAN on a USB flash drive using unetbootin
Mount USB, then replace every occurrence of ubninit with ISOLINUX.BIN in the syslinux.cfg file
sed -i 's/ubninit/ISOLINUX.BIN/g' syslinux.cfg
Replace every occurrence of ubnkern with DBAN.BZI in the syslinux.cfg file
sed -i 's/ubnkern/DBAN.BZI/g' syslinux.cfg
Your bootable DBAN usb stick is ready now.
Use rufus to create bootable usb. This method eliminates
sed fix and seems not causing
dban can't open /proc/cmdline error when version v2.2.8 has been used. However I was unable to erase data as DBan was unable to detect my SSD drive saying
Error: Disks not found. DBAN could need a driver for this computer
Note: DBAN will boot up and data erasing will start within 10 seconds without any prompt
Erase - alternatives
Shred is pretty good because after it writes a pass of random data (the n number is how many times) it then writes zeros that forces the drive to trim and erase the data. and because it's filling the drive from start to finish it doesn't have the ability to ignore blocks leaving old data behind.
sudo dd if=/dev/urandom of=dev/sd(drive letter)/bigfilename bs =1M sudo rm /path/to/mount/point/bigfilename or sudo shred -fvz -n1 /dev/sd(drive letter)
