You guys need to watch the CEO of TECHFUSION DATA RECOERY on this news page. He declares that overwritten data can be recovered and he declares they did it in a case.  The guy does not seem to know the proper information, but you decide! Comments on his process accepted!

Never answers how they recover from wiped area?

Says when it is wiped they can recover part of the data, which means
may be recovering from non wiped area, may be from prev bad sectors !!

Saying you recovered overwritten data on a case in Turkey is like saying 
"I have a girlfriend, she's from Niagara Falls - you've never heard of her."

I have read scientific papers that say even the electron scanning microscope doesn't work well enough to recover a large amount of data.  I tend to believe them a lot more than this guy!

Does it make any difference if data has been wiped out by software (even using some obscure math algorithms) or hardware, such as DeepSpar or some other equipment?  It shouldn't i think...

Ah.. You guys are just jealous that you don't have the magic process of recovering the supposed "data". I have some oceanfront property available in colorado if anyone's interested..

As long as it wipes the Physical drive, it does not make a difference. Now some file erasers and such are not so efficient.

That was pretty funny :) A "regular" recovery would cost less than
$5,000 and a "sophisticated" recovery will cost $50,000.

Pretty big statements to make on TV. I think he's full of you know
what :)

Guy seems full of it.. I doubt very much he has got an MFM, and, if he
has it would take him a least a year to read in raw and remap for a
small drive, assuming he can find the correct encoding of that exact
drive. and dont get me started on defrag! lol.. Its as Dave says: its
a bad wiping software. (assuming the whole drive was done) and,
perhaps he knows how to reverse the pattern because its calculable,
very much doubt it tho. Or there are other copies of the data which he
can carve out from unallocated etc - Even clearing the g list and
imaging is never going to get exactly what u want back. But it will
hold up the argument that if u didn't erase properly, then you can say
that it is possible to get data back from a wiped drive.. Nice
marketing job bud!

This is total BS... One person taking advantage of an uneducated
public and the media hype on a big case...

News article 1: "Demerjian said engineers would make a copy of his
hard drive and then run its data recovery software on that drive,
looking for deleted files."

So.. if you make a copy.. there is no way you are going to do any
super ultra-dope double-secret proprietary platter bit carving...

Also, it doesn't seem like that much of a technical miracle from a
forensics standpoint. User gets emails, deletes them, then empties
his deleted items folder before the server can do a backup at
midnight.. ok, the emails are either in unallocated space, or if those
areas get overwritten you might find fragments in file slack. I
really don't think the user ended up trying to "scrub" or overwrite
anything on purpose, but I guess those details will eventually get
revealed.

Also, the "famous" case that techfusion dealt with was one in which
the smoking gun (awful pun I know) was pictures. Every forensics
person on this list knows that pictures, depending on how they were
viewed and stored can easily leave traces everywhere. View them in a
browser, they could leave temp artifacts.. there are thumbnail.db
files, depending on what software he used to edit them it could leave
traces as well, last time I researched Picassa it made a new image
anytime you did any digital effects processing on it and left the
original intact, and so on. From the interview you can tell they most
likely did file carving, since he states that the pictures had "dots",
which I can only assume means artifacts from carving that didn't
result in pictures that were 100% intact.

Lastly, did he honestly say that his secret data recovery methods were
so secret that they don't write them down, and try not to have any
turnover and that they keep this stuff in their employees heads?!?
Even the Colone's 11 herbs and spices and the recipe for Coke is
written down.. Hard to write a recipe for snake oil.. \


Lastly I do have to share a bit of humor.. I found his on his testimonials page:

“Thanks for your speedy and helpful data recovery services! You helped
me save years' worth of data. I'll definitely call you again if I have
another hard drive emergency."

I love that they never say things like, "I'll always backup my data
from now on!!" Ahh customers.. God bless them!

Data recover companies do things like this from time to time for
marketing purposes. Whether it is being able to recover overwritten
data or having practical platter reading devices...

An update, the recovery was successful apparently, by another company,
maybe everyone in Boston uses the same witch Doctor.... or maybe the
files were just deleted not overwritten :)

I dare say they were just deleted. Lets face it, not many people
really know what they are talking about when it comes to DR...well not
the general public anyway. Including journalists.
