data recovery

[rcfrgf]

Simple overwrite one pass, D.o.D. 5220 3 passes , N.S.A. 7 passes,
Gutmann 35 passes. In response to the question "Can overwritten data be
recovered?" Yes. As data is written to tracks and recovery programs aim at
those tracks which are overwritten, the best Data Recovery teams sense what
data is between the tracks. The name of this is Advanced Hardware
Electromagnetic Remanence Techniques. No matter how many times the data is
overwritten Remanence remains. An example: 320 Gig HDD with 999 day Internet
Explorer browser history, 46 weeks of data overwritten for 2 months. 29
Recovery programs, 13 Binary,Cashe and Index programs, and 6 Index.dat
analyzers were first attempted in recovery. Results were unintelligible. Sent
to Aero Data Recovery, "Never seen anything like this !" They refered HDD to
ESS Data Recovery. Results : 400,000 lines of excellent readable data. HDD
had been overwritten 3-4 passes ESS could recover to 7 passes. To truly rid a
HDD of all data, it must be Magnetically Degaussed or Destroyed. There are
many examples of this. M.I.T. found data on 158 overwritten HDD. Cost for
ESS recovery, $835 with 2 dvds and a 250 Gig external.

Bull honk, it's a fairy tale. No one has ever been able to recover data
on a securely wiped drive. The ones that you tout as being able to do
this actually offer guaranteed secure deletion services, which pretty
well puts your claim to rest, if they say that they can guarantee secure
deletion then even they cannot recover the data.

Not only that, it's spam. ;-)

must be a mistake

I'm the President of ESS Data Recovery and I wanted to set the record straight. We do not have the ability to recover data that has truly been overwritten even once -no one does. My guess is that the data was not really overwritten. Perhaps a size limitation was set on the drive (using jumpers) and we recovered what was left -or perhaps bad firmware set the max LBA to a value that left much of the drive untouchable. Bottom line, nothing that was truly overwritten was recovered. We really appreciate the positive post, but I've got to make sure rumors don't get spread around. Thanks again. -Ben Carmitchel
