Re: clearing data from partitions



One quick, but kludgy way to do it would be say..

cat /dev/zero to each of the partitions for a few seconds.
that will murder the partition, and it will end up basically broken.
at that point, youd want to mke2fs or something on each one.

If you make a text list of all the partitions you want to do this to
you can script it!

something like..

bash# for i in `cat partitions.txt`; do dd if=/dev/zero of=$i bs=1024 count=50; mke2fs $i; done

that should go through the textfile, overwrite the first ~50k of each partition with zeroes
then mke2fs it.

Hope this helps!

Grub picks up everything and I have a quite large menu.lst file.
I want to find the safest way to 'clear' the contents of partitions
that I no longer need.

I know I can use fdisk or cfdisk to delete each partition, immediately recreate and then format with say ext3.
Is there any simple way to accomplish what I want?

John.

P.S. I've tried deletions in the menu.lst file, but the next time
try another distro, grub picks up everything again.
