I do not feel that it is appropriate in this forum to reduce ourselves to personal attacks and I appreciate the same respect in return
Absolutely. Personal attacks will NOT be tolerated in these forums. Any members engaging in such behaviour in the future will have their accounts removed without further warning.

Please be advised of the following:
- Our colleague Nikola has suggested that -quote- "HDD doesnt need to be oppened at all.I m using a tehnici that extarcts data from badd hdds only bay rewriting it's firmware,(firmware is on platter) In 90% of maxtor I can do it .SO the hda replacment is not so needed."????????
I cannot understand how could the data be read without the head, if that is true then IBM along with all HDD manufacturers have missed that technology!!
- Cooling-off a head of a damaged HDD is only carried out under strictly controlled parameters, therefore putting a HDD in a freezer could easily
cause damage on the platters and the head, subsequently a permenant loss of data could be achieved.
- A steady decline in the temperture of a damaged head can be achieved by simply leaving the drive to cool off for 2 hours.
- To attempt to recover a damaged HDD in clean environment without any knowledge in the field of hardware engineering would be classified a recipe to disastor.
- If one requires to acquire such knowledge then text books are required in addition to intensive practice in the clean rooms. Therefore to pick up magic tips from the internet could be described as superficial as suggesting learning how to drive from gathering tips from the internet.
Learning is a slow curve and one has to cover many subjects to have an adequate understanding of hardware engineering.

I'm sorry, what is what?

that was very personal
I would argue with that, but this deviation from the original thread has probably run its course. The ethos behind this community is the sharing of information in a respectful and friendly environment, let's keep that in mind and move on.

OK that is nice can man from london share somethng just to
show some god will, I am still vaiting.
Nikola
I willl then
Heating a damaged HDD or cooling it off is sometimes applicable during the data recovery, however I beg to point out that it is carried out under strict conditions. Please be careful when doing so as any abrupt change in HDD temperture could easily jeopardize any recovery chances.
If your data is too valuable to be risked, then it is advisable to avoid trying it.

Please forgive me if I sounded abrupt, but it was a reaction to a point that could be considered as unscientific, I hope my apologies are accepted and my initial reply did not cause any offense. Thanks
Interesting thread . . . but back to the original subject matter (data recovery techniques).
The data recovery industry has long been surrounded by myths, falsehoods and misinformation. It's very difficult (if not impossible) to get solid information about the subject. For those seeking insight - I direct you to our white paper - "
(Note - this is not an advertisement or marketing document)
It was written for ActionFront Data Recovery by Charles H. (Chuck) Sobey, Chief Scientist of ChannelScience.
It's a pretty technical read - but well worth the time for those interested.
He examines the myths and realities of extraordinary data recovery capabilities, including Magnetic Force Microscopy and spin stand technologies. It also questions the "reported" capabilities of commercial or government agencies to recover overwritten data.
The white paper presents a comprehensive overview of the data recovery industry's current methods and techniques and provides a highly technical description of current hard disk drive technologies.
(Note a full ASCII text version of the white paper is at this link - but to obtain a formatted PDF file with photos and charts - an email address is required and our server sends an autoreply copy of the document. This is for control purposes and no mailing list is created or maintained.)
Many thanks for that Nick, and welcome to Forensic Focus.
I'd be happy to reproduce a couple of sections from the white paper here at Forensic Focus in our "Articles & Papers" section, with a link to the full paper. Please let me know what you think, either via the forum or a PM.
Kind regards,
Jamie
