"Eraser" new release
For those of you who use it, or are interested, there is a new (15 December 2009) stable release that works with recent versions of Windows.
Basically it provides secure deletion of files and folders, whole disks etc. It also has a "secure move" feature.
It will also wipe "free space" including alternate data streams and cluster tips
http://eraser.heidi.ie/download.php
It is true "freeware", and the source code is available under the GNU Public License"
I have used it for a number of years (since Win 98 actually ) and can personally recommend it. I know of no publicly available commercial product that is better.

Hi xqus,
You are very welcome.
If there is anything specific you would like me to test for you just let me know.
EDIT:
I did a bit of research:
January 1, 1601, is used as the base of file dates [1] by Microsoft Windows.
January 1, 1601, is used as the base of Active Directory Logon dates [2] by Microsoft Windows.
ANSI dates are counted from 1601-01-01 and were adopted by the American National Standards Institute for use with COBOL and other computer languages. This epoch is the beginning of the last 400-year cycle by which leap-years are calculated in the Gregorian calendar. The last year of this cycle is the only one divisible by 100 that is a leap-year, which was the year 2000, and which was followed by a new 400-year cycle beginning with 2001. 32-bit versions of the Microsoft Windows operating system count units of one hundred nanoseconds from this epoch. http://www.decimaltime.hynes.net/dates.html
So that probably explains the 1601 date?

I think I'm actually going to test it a bit myself, thanks. I have a couple of harddrives that I'm going to throw away. So I think I'll just try Eraser, and see if I'm able to recover anything when I'm done.
Thanks!

Most likely.... the actual date of a file is the 'base date' plus a numeric value - the 1601 date implies the numeric value is removed, and so the information displayed is the 'base date'.
Base date = 0 (numeric value)
So, on a file with the date of January 1, 1601 has a date value of 0.
January 2, 1601 has a date value of 1
January 3, 1601 has a date value of 10
January 4, 1601 has a date value of 11 and so on....
Correct me anyone
