Shredding algorithms - DoD 5220-22M vs Gutmann

by jtryan789 / March 13, 2008 7:00 AM PDT

I know the textbook explanation difference between these two, but am interested in real world experiences you may have had in the efficacy of these two algorithms for preventing restoration of files that were shredded from:
1. Standard hard drive - internal or external
2. Flash memory USB key

What you already know.

It is close to...if not...impossible to erase a HD.
Given enough time/effort/money....data can be recovered.
Of the methods you mentioned.
They may give a data recovery house a little heartburn....but just a minor speed bump.

An alternate answer to your question
by Juicebox77 / March 13, 2008 9:43 AM PDT

I would recommend listening to the latest episode of Security Now with Steve Gibson and Leo Laporte. They review True Crypt 5 and discuss how you can use whole drive encryption as a method to prevent data recovery. Using whole drive encryption in conjunction with file wiping/erasing can be a very compelling method to keep your data, erased or not, secure.

It isn't a direct answer to your question, but I think that the result could be what you are looking for.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
