Are we talking about physical shred (hammer, paper shredder, acid, etc), or actual file shredding that you asked about 30 minutes ago and which got closed as duplicate? –  Gnoupi Mar 29 '10 at 13:03
    
@gnoupi file shredding –  bala3569 Mar 29 '10 at 13:05
    
Ok, actually, the other question (superuser.com/questions/4678/…) doesn't really contain a solution to apply for a single memory card, only to wipe an entire computer. There is probably another question about securely erasing individual files, trying to find it. –  Gnoupi Mar 29 '10 at 13:08

A Blentec blender will do the job. (I couldn't help myself from answering with that)

Seriously,though, on linux, a dd if=/dev/random of=/dev/sdx where sdx is your flash card will work fine. On windows, I'm pretty sure that CCleaner carries the option of multiple erasure of a custom folder. you can also use SDelete or Secure Erase Util or even Eraser

When a duplicate is shown in comments, please refrain from answering the question, as it will most likely be closed. Consider adding your answer on the "original" question, if it wasn't given already, to keep answers in one place. –  Gnoupi Mar 29 '10 at 13:18
    
Nobody had commented when I started to answer. But you're absolutely right Gnoupi. I should have flagged for mod. –  brice Mar 29 '10 at 13:51
    
no problem, though. It was only a suggestion for next time. SDelete and Secure Erase Util haven't been suggested yet on the other question, I see, you could port a part of your answer on it. –  Gnoupi Mar 29 '10 at 14:16
