Looking for a way to zero-out a flash card (any format CD/SD/MS) so that it starts completely clean? By that I mean not just formated but all zeros or a fixed pattern.
It will be formated later and used to test photo recover software so it needs to start blank so that nothing is found by the software to start with.
Presently running OpenSUSE 11.2 64-bits, if that makes a difference.
