I have just begun to research this topic and I would like to know from anyone's personal experience which disk wiping utilities are the most effective and secure. I have looked into PGPwipe and BCwipe and have seen many others. Any suggestions on a good starting point??

I use a program called viewdisk (cpr). It has the ability to write a specified binary pattern over the entire disk. I write over it 5 times - the government specifies 3 times with different patterns. We go a little farther.
That makes it pretty unreadable.. with any forensic tool. Then a nice low level format with something like maxllf.

This doesn't just clean traces of files off though - if thats what you want. It wipes the entire drive.

Wipe Drive and DBAN (Darik's Boot And Nuke) are good ones - both bootable and pretty self-explanatory. DBAN is very thorough - too much so for some people. It can make up to 32 overwriting passes, I believe. I think it's on Sourceforge.net, but you can do a search for either of them.

Actually I do want a tool that wipes free space, including slack space, extra space on files, and page files. I'm not looking to clean the entire drive. This is to be used for ensuring that temp files and deleted files are truly gone, even when doing low level disk reading.

You can use Window Washer to clean out the temps, history, recycle bin, e-mail trash, and so on. It has an option to over write those files several times over. It also support over 100 plugins and you can create your own.

I've used BCWipe back when it was still free, the latest version is shareware. I know of a site where you can still download the free version if you're interested in it. BCWipe works good, and you can wipe the swap file with it also, though the older version doesn't support that feature. You can wipe slack space also.

There's also a free program called Sure Delete that offers some of the same feature that BCWipe does.

I don't recommend wiping slack/free space and running it on the whole system. You can (in my opinion) really screw your system up doing that. What if it overwrites a good system file by accident or something else. Sure those programs are great if you want to wipe some private files, or wipe the recycle bin, or all your old e-mail, your history and temp files, but I'd never run in on the whole system at once.

I'd first recommend Window Washer to you, check it out and see if that is what you want and need. There is also Evidence Eliminator that is good, check that one out also, it'll wipe all those secret files.

You just got me cracking up over here Laughing Laughing ! Yes in deed they are spammers, I've seen their popups, they spam every news group, flood every e-mail box, and I am sorry to try to spam this forum with their name.

Did I really say Evidence Eliminator, I must have meant ahh... E-mail Eliminator, yes that's it! E-mail Eliminator, it (let me see, what does it do...) it wipes your old e-mails, that's it EE!

Huh! Am I in the clear now ST? Very Happy

I assume you have seen the Sarah Dean page at fortunecity

Good comparison of disk shredders if a little outdated.

I use BCwipe as part of Bestcrypt. I have used pgpwipe which in some quarters is reputed to be more secure. I can't really see it. BCwipe also includes features for wiping swap file, temp folders, cookies, history etc. The only thinhg about it is it takes a hell of a long time.
