Talk:Gutmann method

message: Does Gutmann's paper mention any join experiment involving the FBI & NSA?
Many of the aspects of Gutmanns paper, although very interesting, are not proven in any way. I removed some of these from the article and added som hopefully NPOV criticism Zelda 16:29, 27 July 2006 (UTC)
replies: text: Just adding some criticism doesn't make the Article NPOV. Could someone else look in to this - there are no sources cited that MFM (magnetic force microscopy) can't recover deleted files, could someone add them who is into this topic, thx --193.171.240.2 05:53, 23 March 2007 (UTC)

text: Can you provide refs for any method that can recover overwritten data?  I note that no companies currently offer such a service.    Having said that, this article is about the obsolete Gutmann method, and so I guess it should mention what could be done with drives around when he wrote the paper, and then maybe mentioning the fact that those methods don't work for any modern drive.

message: I'm not an expert in this field (so please correct me if I'm wrong), but logic says that, on the third column of the second table showing an example of one process of recovering data, the previous signal should be +10, not -10, because the difference is +1. Can someone check this? Thanks, HANtwister (talk) 23:58, 28 December 2007 (UTC)
thread_title:  Believed Slight Error In Technical Overview 

message: A user known only as 189.25.15.219 removed a reference to a paper from the National Bureau of Economic Research (NBER) that was critical of Gutmann's original paper.  The reference was well-linked, the NBER is a reputable source (see the Wikipedia article on same), and their critical paper is topical and well-written.  I'm especially suspicious, because this is the only Wikipedia edit ever recorded for 189.25.15.219.  I've re-inserted the reference.

message: Gutman said:
* In the time since this paper was published, some people have treated the 35-pass overwrite technique described in it more as a kind of voodoo incantation to banish evil spirits than the result of a technical analysis of drive encoding techniques.
The article says:
* Gutmann himself has noted that more modern drives no longer use these older encoding techniques, making parts of the method irrelevant. He describes the method's common implementations "more as a kind of voodoo incantation to banish evil spirits than the result of a technical analysis of drive encoding techniques."
That is a very appalling misinterpretation. Syced (talk) 09:53, 2 August 2015 (UTC)
replies: text: What's misinterpreted? Gutmann never intended his paper as the basis for a "method" and he's used a colourful term to describe his disapproval of the blatant security theatre that's resulted - David Gerard (talk) 10:26, 2 August 2015 (UTC)

message: The technical overview states:
One standard way to recover data that has been overwritten on a hard drive is to capture and process the analog signal obtained from the drive's read/write head prior to this analog signal being digitized.
This needs a citation, that establishes that it is true and there needs to be some evidence and discussion of its feasibility,
It is well known, as shown in other comments here,  that this a controversial claim.   Without citation, it should not be allowed.  — Preceding unsigned comment added by 67.86.77.196 (talk) 15:50, 15 December 2019 (UTC)
