Take my word for it: it works just fine in XP, regardless of the fact
that they have not updated what it says on their site.

ok, so this is the best (most secure) out there?

What about the spybot secure shredder?

I don't know . . . it's good enough for me. Depends on what
your requirements are. I had good experiences with Eraser
some years ago, but I prefer a command-line program like
sdelete rather than a GUI. What kind of top-secret files
are we talking about shredding?

What kind of top-secret files
are we talking about shredding?

and why are you asking me this? Who do you work for? Was that you knocking
on my door?

All, I want to do, is be sure noone can ever pull out files that I chose to
shred. U know nsa and all those goons.

Actually, you can download and use PGP for free. Their site says that
after the trial period expires, it reverts to a "limited" version. It
still performs everything that I need, including its secure deletion
(called "wipe"). And I use an older version -- 8.0.3.

I can't imagine needing any more secure file deletion than PGP offers.
Depending on who you ask (this includes "devotees" in the newsgroup
alt.security.pgp), PGP can't even be decrypted/recovered by the NSA. I
wrote the NSA asking about this, and they wouldn't answer. They told
me that they can't confirm nor deny this info. That somewhat told me
that they are indeed unable.

However, in another post, someone mentioned Eraser
(http://www.heidi.ie/eraser/). The link at download.com for this
program mentions writing zeros and/or zeros and ones over the deleted
space. And this prog is free.

Also, I'm impressed with the shredder in Spybot, which is also free.
You can choose your desired number of passes from 4 up to whatever (I
didn't look for the max).

HTH,

Why, yes, it was! And you kept saying "Dave's not here, man!"
All, I want to do, is be sure no one can ever pull out files that I chose to
shred.

Here's yet another good, "secure delete" program. Try going to
www.zdelete.com. They have a free version.

Their description: "ZDelete - Cleanup and hard drive eraser utility
permanently deletes selected files, folders, directories, Internet
browser caches, surfing histories, and cookies. DoD 5220.22-M
compliant." (Note: Microsoft .NET framework must be installed.)

Anytime you see "DoD 5220.22-M compliant for standards of cleaning and
sanitizing/sanitation", you know it's going to overwrite the HD space
that the deleted file once took up. PGP says it, and even goes much
further upon your parameters.

Another program you might be interested in is Folder Lock
(www.newsoftwares.net/folderlock). The GUI looks like it's made for
children, but believe me it works great for securing files, folders,
etc. They claim that absolutely no one can break into the password
protected folder(s). You can even hide risque photos of Nancy Kulp,
and no one will be the wiser!

If your hard drive is physically available, then one can get data off it
no matter if you wrote zeros to it.

No. The residual patterns of the data are still there. If the platters are
intact the data can theoretically be retrieved by someone with the right
skills and equipment. If anyone has the skills and equipment may be in doubt
but the possibility is there.

Way! Yep. Folder Lock not only locks and password protects files and
folders, but it can encrypt in addition to password protecting. It
uses a very similar encryption algorithm to PGP.

Also, about ZDelete, you can go to www.zdelete.com/dod.htm and read
detailed instructions about the DoD's guidelines for sanitizing (US
Department of Defense 5220.22-M Clearing and Sanitization Matrix). I
went to www.dod.gov and they have numerous docs there about securing
data, erasing data, etc. Pretty incredible.

SDelete on F drive:

run time error '52'

bad file name or number.

Reboot and got this again. So, did it finish the drive or stop on error?

Eraser:

File~new task, unused space on D
Edit~preferences~erasing, unused disk space tab
Edit~properties, unused space on D

D listed on screen as Type: unused disk space

select above "D" and click task~run, and Warning message sounds like all D
will be trashed.

who recommended ZDelete? It costs money!
P

I did. And there is a FREE VERSION at http://www.zdelete.com. Click on
"Download Free Version" on the left.

Zdelete: Good.
Eraser: Very good.
PGP wipe: Very good.

Other info that might be useful for sharing in this thread:

Files can be totally deleted in the following "relative" aspect: The
space that the deleted file once took on the HD can be overwritten
several times by a good program like the "wipe" utility in PGP (free,
and it wipes a minimum of three times), and the ZDelete program (the
free version only wipes once with zeros, I think). To get a HD totally
clean just like a brand new, "never been used" HD, you have to follow
step by step the DoD guidelines. Check out the www.zdelete.com/dod.htm
website. It's amazing what the DoD guidelines are for completely
wiping a HD so that it's like new (totally blank).

Folder Lock (www.newsoftwares.net/folderlock) is the best for saving
and securing, in my opinion. Like I say, the interface looks like it's
made for children, but believe me it works great for securing files and
folders. Plus, when you click on "Lock", you are given three options:
Lock (fastest), Lock and Scramble, and Lock and Encrypt. This program
is very small, but it does an amazing job and has several options that
you can change. The Folder Lock people refuse to answer my question
regarding continued use after the 35-usage limit. So, as far as I can
tell, we only have to put up with a 5-second "countdown" nag screen.
Also, it will immediately lock upon a power outage.

Also, don't discount the (minimal) power of the Windows defrag utility.
It may not overwrite with zeros, but it overwrites, nonetheless.
After deleting any number of files, run defrag and it can prevent an
"average" user, like a brother, sister, children, etc, from performing
a simple undelete on said file(s). Even an "average" computer geek
most likely won't bother with a halfway sophisticated recovery program.
I remember using the old DOS version of Norton Utilities, and its
defrag gave a user the ability to "view" the contents of any given
sector (or block, I can't remember). But, once it was finished, you
couldn't see the old data that once was there.
