berdy Posted July 24, 2005 Share Posted July 24, 2005 no one got any advice?? <{POST_SNAPBACK}> Yes. it'll do no harm. you may experience a long shutdown thats the only difference. but you can do it once in a while Link to comment Share on other sites More sharing options...
oli Posted July 24, 2005 Author Share Posted July 24, 2005 how much time does it add to a typical shutdown?? Homer: I never apologise, im sorry Lisa. Thats just the way i am Link to comment Share on other sites More sharing options...
berdy Posted July 25, 2005 Share Posted July 25, 2005 It varies. It depends on your system. you have to do it and see. Link to comment Share on other sites More sharing options...
Tarun Posted July 25, 2005 Share Posted July 25, 2005 There's not really much security at all in clearing your pagefile at shutdown, as you would have to overwrite that space with data at least seven times. Link to comment Share on other sites More sharing options...
oli Posted July 25, 2005 Author Share Posted July 25, 2005 does doing it actually make startup quicker Homer: I never apologise, im sorry Lisa. Thats just the way i am Link to comment Share on other sites More sharing options...
GreenWhite Posted July 25, 2005 Share Posted July 25, 2005 Clearing page file upon shutdown will definitely slowdown the process. I've done that in the past and if you have the patience, go for it. It all depends on the size of the pagefile. The larger the pagefile, the longer the shutdown gets. If you are paranoid about wiping the tracks of your activities, I suggest you do this. Since you already have CCleaner and I assume you do. Go download the Eraser program. This is a secure delete software and its free. It has all the Guttman you want. Now use CCleaner as a reference of what it cleans and transfer all that into Eraser. Now all the tracks not only get wiped out, they will be securely deleted. You will always have to cross refer it once in a while because there will always be new paths and files for deletion. Try it out. Link to comment Share on other sites More sharing options...

bpm3k Posted July 25, 2005 Share Posted July 25, 2005 DoD specs <{POST_SNAPBACK}> Assuming your two abbreviations are a reply to me. What about "U.S.Department of Defense Sanitizing (DOD 5220.22-M). The algorithm using 3 passes of overwriting."? It seems dod recomends 3 passes. DoD 5200.28-STD Link to comment Share on other sites More sharing options...
Tarun Posted July 25, 2005 Share Posted July 25, 2005 Look in Eraser, there are two DoD items. Three passes = US DoD 5220.22-M (8-306. /E) Seven passes = US DoD 5220.22-M (8-306. /E, C and E) Link to comment Share on other sites More sharing options...

It's a standard one pass delete. You'd still have to overwrite that free space. Link to comment Share on other sites More sharing options...
DjLizard Posted July 25, 2005 Share Posted July 25, 2005 Actually, it's not even a one pass delete. Windows will only mark it for deletion... the clusters are really deleted later, once they have been re-allocated to and written to by a new file.

Moderators Andavari Posted July 25, 2005 Moderators Share Posted July 25, 2005 Wouldn't defragging the hdd place other data in the particular disk clusters to make the removed data non-recoverable? With the size of current hdd's I can only imagine how long it would take to just do 1 pass of overwritting with an erasing program let alone 3 or 7.

DjLizard Posted July 25, 2005 Share Posted July 25, 2005 Yes, that is correct. Defrag screws chances of recovery, but only by one pass. Advanced forensic engineers can still retrieve data. Yeah, secure-wiping a drive these days takes an ungodly amount of time. If only hard drives were solid-state...
