RE: Fash cards sanitization from Nokia Symbian and WM5/6

[Luis Lopez Sanchez <luis.lopez () atosorigin com>]

Hi Geoff,

Thank you very much for clarify me this matter, I'm not very familiarized with solid state memories yet, until now I've 
been working with hard disks sanitization only ... But I can understand your explanation and their physical 
considerations.

Please, let me drop the question again, I would need some tool for WM5/6 and Symbian to carry out a DoD wiping for 
external flash ... Do you know anyone to use from mobile devices directly? I know that performing a 'Hard Reset' it 
would get a internal flash wipe but how I can wipe securely the external flash from the itself mobile device.

Thanks in advance,

Regards,
