AVIRA has a free one that is pretty effective, same company that makes AntiVir.
Nice find!

I dont understand how these programs work. Where do these deleted files reside? I must have deleted 10 gigs of stuff off my d: drive and Im wondering where it goes since my c: drive is the same size its always been (~ 9 gigs)
Simplistic explanation is that when you delete a file you are actually deleting the pointer in the File Allocation Table that points to the first sector the file data resides in. The sectors that actually contain the data are now marked as being open and can be used when a new file is created. All the recycle bin does is prevent the second part from happening until you say delete them for good.

Standard DoD 5220.22-M
US Department of Defense in the clearing and sanitizing standard DoD 5220.22-M recommends the approach "Overwrite all addressable locations with a character, its complement, then a random character and verify" (see table with comments) for clearing and sanitizing information on a writable media.
US Department of Defense 5220.22-M Clearing and Sanitization Matrix
a. Degauss with a Type I degausser
b. Degauss with a Type II degausser.
c. Overwrite all addressable locations with a single character.
d. Overwrite all addressable locations with a character, its complement, then a random character and verify. THIS METHOD IS NOT APPROVED FOR SANITIZING MEDIA THAT CONTAINS TOP SECRET INFORMATION.
e. Overwrite all addressable locations with a character, its complement, then a random character.
f. Each overwrite must reside in memory for a period longer than the classified data resided.
g. Remove all power to include battery power.
h. Overwrite all locations with a random pattern, all locations with binary zeros, all locations with binary ones.
i. Perform a full chip erase as per manufacturer's data sheets.
j. Perform i above, then c above, a total of three times.
k. Perform an ultraviolet erase according to manufacturer's recommendation.
l. Perform k above, but increase time by a factor of three.
m. Destroy - Disintegrate, incinerate, pulverize, shred, or melt.
n. Destruction required only if classified information is contained.
o. Run five pages of unclassified text (font test acceptable).
p. Ribbons must be destroyed. Platens must be cleaned.
q. Inspect and/or test screen surface for evidence of burned-in information. If present, the cathode ray tube must be destroyed.
For more information regarding clearing and sanitizing security standard DoD 5220.22-M see US Defence Security Service Web Site (Chapter 8).
Sounds effective, but not really time efficient for when the FBI comes a knockin.
m. Destroy - Disintegrate, incinerate, pulverize, shred, or melt.

NO ONE will interfere with the reaction once it gets started

sorry ... it took me THAT long to actually view it
the neighbors called the cops also - on me - i *was* a kid in HS when i tried it ... with Magnesium thermite ... lit about 2 square blocks up late at night ... brighter than day ... but i knew what to expect and had welders shades available
basically the magnesium oxide reacts at extreme heat with the Al to create elemental magnesium and that in turn burns white hot ... much better 'n fireworks.
and nothing was *harmed* in my old experiment ... except perhaps my neighbors' sanity who might have thought the aliens had landed
fortunately it is dead silent [except for a *hiss*] and the smoke blew away before they figured out *who* did it

so as not to *clog* Hot Deals ... the OP's thread is about File Recovery,
i made a thread in OT:
Deleting Sensitive Data OFF your HD ... *permanently*!*
as i said ... the 'statute of limitations' ran out ... MANY years ago

not that there was any damage

To sum up the previous post, Freeundelete was a VERY hot deal for this data recovery. And fast. It should go to the head of the line
