Hello,From what I understand you are looking for a software application on a WM5/6 and Symbian mobile device that wipes external flash memory attached to the device?
When looking for products with this type of functionality I always have a look at the Common Criteria Portal to ensure that the product has been through an evaluation process and is suitable for government use.
If the data is sensitive why not destroy it as you can just remove the flash card.

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, -- Luislo http://luislo.blogspot.com "I speak for myself not Atos Origin"-----Original Message----- From: gjgowey () tmo blackberry net [mailto:gjgowey () tmo blackberry net] Sent: jueves, 27 de septiembre de 2007 19:11 To: Luis Lopez Sanchez; listbounce () securityfocus com; security-basics () lists securityfocus com Subject: Re: Fash cards sanitization from Nokia Symbian and WM5/6 Why would you need gutman to sanitize a flash card? Gutman is written specifically for taking the inaccuracies of writing to magnetic media into account. Flash cards don't suffer from those problems and all you're likely to do is make them burn out faster. I wouldn't do anything more than a regular dod wipe on flash cards and even that is overkill.

I have been googling sometimes for this recurrent matter with no successful. I'd like to know if somebody know some app to apply the Guttman method (yeah! Of course, I know this is a any obsolete method but to me it would be enough to start) to SD and micro-SD flash cards from Windows Mobile 5/6 and Nokia w/ Symbian 80 3rd ed. based hardware platforms (such as HTC/QTEK for WM and N*/E* Nokia Series). I am searching for a system to wipe or sanitize flash cards directly from the two mobile operating systems based platforms. From a PC with a simple flash reader reader all is easy, but from a mobile device is not so much... ¿Any idea? PS: I think that something like 'dd' GNU tool for WM or Symbian could be useful as a first approach, but I haven't time to port it (and I don't know if I would be able to carry out it!). Many thanks in advance.
