Sorry, but I can't really understand why people insist on using Gutmann's method for wiping. 35 passes? What is the point? 1 pass and pretty much any forensic analyst would say that there is no point looking at the blocks where the data used to be. 3 if you're really paranoid. 35 is a waste of time. Unless you're worried that some alien race may have the technology to rebuild the data because they can work out the miniscule variations in the fields. Personally, I can't see it happening. DoD standard is good enough. On a related note-does anyone know if eraser wipes the block as well as the inodes for the data? Eraser does have a nice feature where it erases free space(ie unallocated blocks). So all the stuff that had been 'deleted' is then wiped. -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of security.xentek Sent: Tuesday, May 01, 2007 7:54 AM To: security-basics () securityfocus com Subject: Re: Secure deletion on Mac OS X Safari has a private browsing feature, as well as a delete all history feature that should be pretty comparable to CCleaner. + eric m. + http://xentek.net + + + + + + + + + + + + + + "Security is mostly a superstition.

I use Eraser to securely delete files on my Windows XP desktop. I use CCleaner to securely delete my surfing history, cookies and cache. I'm looking for similar freeware secure deletion tools that can be used on Mac OS X. Mac OS X comes with its own secure deletion option but it does not have any options to configure. How does it fair against a tool like Eraser? Is there a better tool for Mac? How about a freeware tool to securely clear my surfing history, cookies and cache? My preference is for both tools to support the Gutmann method. Any recommendations would be appreciated.
