Got a harddrive from a friend, and I would like to know how to wipe it CLEAN. Don't want any data retreivable. Thanx in advance.:angel:

open it up, and use some soap and water. Make sure to go counter clockwise....this is imperative b/c if you dont then you might kill the drive. Once this is done...soak in water for 24 hrs....
just kidding

You forgot to soak it in a sink for 30 minutes...

They are just playing with you. :) But it does resolve your question.

Best thing to do is just search around on the internet for programs that can do it. A couple I have found are here: http://www.filetransit.com/view.php?id=2900 and http://www.sofsol.co.nz/p0001898.htm .

The only way you can do what you are saying is with a software solution, but chances are you'll probably have to pay for most of them.

Hey FlatHead:wave:

I think this link will fix you right up - and coming from Mr. C, you can bet it's free.
http://home.att.net/~craigchr/mutilate.html

I do believe that should take care of the problem for you in short order.
There are indeed several commercial solutions available, but you will also find other free options in addition to the program I linked you to.

So give it a try, what have you got to lose?
Except some data maybe:D

Good luck with it.

Don't take it to heart, you weren't exactly flamed at all. Think of it as a bit of the not uncommon TweakTown pull-of-the-leg.
Even Admins need a bit of lightheartedness once in a while.

The people at Tweaktown are everyday people just like you and like normal humans that we are (well with the exception of Beefy..[he's a Juggernaut]) we kid around and have fun. We aren't tech support or anything like that. If can help we will and we might mess around a bit while we are at it. So don't take it the bad way...we sure don't mean to be that way. So...like i always say....

BE COOL STAY IN SCHOOL!

You can retrieve data after a fdisk and format, but if there is new data put on top of the old data...then you cannot retrieve it. At least that is what i have heard! :devil:

Wow that is amazing... I did not realize that!!!!

Beefy
09-26-2002, 11:24 AM
that's why you need software to make sure things stay deleted. :) The old NSA standard set all bits on the drive to zero, then overwrites the disk three more times, setting all the bits on the disk to one, then zero, then one again... and the Department of Defense method is heavier still...

Mr. C
09-26-2002, 11:35 AM
As I understand it, the NSA and other agencies have the capability of reading trace residual magnetism(is magnetism the right term??) from many many previous writes - we're talking hundreds here!

Of course such recovery techniques are pretty much James Bond type scenarios. The cost of doing that depth of recovery is ridiculously expensive.
Of course if we got our hands on Saddam Hussein's HDD you can bet your *SS that we would spare no expense to get the data off that rascal:D

But for the budget most folks are on, a little freebie software program is sufficient to cover your tracks. The program I linked to is capable of 297 overwrite passes - so unless you are a celebrity or a criminal, you'll be in pretty secure shape after using it:thumb:

and yeah, you'd be amazed what can be pulled off a formatted drive

ReSpAwN DeMoN

has anyone here actually tried such a thing!?!!?!? or is this "just what you have heard"

cause truthfully after deleting the partition the drive is factory new. Or are you talking about the MBR? what if you delete that too!?!!? the drive is gone make a new partition and its fine. Not even the FBI can get access to it. I trully think so!

Beefy
09-27-2002, 09:53 AM
after deleting a partition the drive isn't 'factory new'... It's like drawing on a piece of paper with a pencil. You can rub it out, but the paper isn't new again... you can still see faint marks of what was drawn on there. HDD's are kind of the same. When you delete them, as Mr C said, there is a faint magnetic residue that is left on the side of the track where the drive writes, and with some decent equipment, they can actually retrieve data that was previously there. :)

ReSpAwN DeMoN
09-27-2002, 12:29 PM
eh I'm still a bit skeptical about it but I'm not gonna argue the fact. About how expensive is this "decent program" gonna cost? lol I'm sure its several hundreds right? Or is this the kind of software that you can get for free from download.com saying things like "RETREIVE YOUR DATA AFTER IT HAS BEEN DELETED!" no?

Mr. C
09-27-2002, 12:47 PM
ReSpAwN DeMoN you are absolutely correct.
The level and type of recovery I spoke of is not available through a download site. While yes, software is involved it also requires specialized equipment - and I would assume disassembly of the drive to be examined. Very expensive stuff!

That is why I say that unless you are a celebrity or a criminal, the freeware I linked to is enough to get the job done for us average Joe's.

Remember last year when that dood (financier, banker or some such type guy?) sold his PC and the purchaser was able to get Ringo Starr's financial records from it? Big news - and a huge embarrasment for the financial institute.

But, I don't have to worry about such things too much:D So a bit of freeware should do the job nicely for me.


On an interesting - yet wholly unrelated topic; well, nearly unrelated;

There is going to be like a contest of sorts in the near future for folks who specialize in recovering data from audio tapes. The winner will actually get an opportunity to attempt to "bring back to life" the missing minutes of former President Nixon's Watergate tapes.
Pretty much based on the principals Beefy described in recovering data from a HDD. Residual magnetism and such.

I don't claim to understand it, but the science definitely supports the practice.

That is certainly a cool thing to read about...any links?

Mr. C
09-27-2002, 08:46 PM
I haven't found the article I originally read, which was about a serious audiophile with a huge collection of antique recording equipment. He in fact owns equipment exactly like that on which the tapes were made and erased with - along with intimate knowledge of the hardware and its intricacies. It seemed to me if it can be done, this might be the fellow to pull it off

But there were several news stories as well as government information releases on the topic.

http://www.usatoday.com/life/cyber/tech/2001-08-08-nixon-tapes-tech.htm

http://www.archives.gov/media_desk/press_releases/nr01-84.html

http://abcnews.go.com/sections/politics/DailyNews/watergate010809.html

One of the main criteria for the chance to recover the missing audio is that it must be proved that the recovery will in no way harm or degrade the original tape.

Sounds like quite a challenge, and few people are really qualified for the job at this time.
Kinda' cool though, unlocking history's mysteries and all:thumb:

ReSpAwN DeMoN
09-27-2002, 09:51 PM
and I would assume disassembly of the drive to be examined.

Even though it was just an assumtion and not exactly the truth. Doing this would basically make the drive unusable if anything.

As for those tapes ya that is interesting. I'll read those links later today.

Mr. C
09-28-2002, 12:15 PM
The object is not to obtain a servicable hard drive in that kind of circumstance, it is only necessary to recover the data which resides upon it.

I mean, would the USA really give a dongo's kidney to change the OS on Saddam Hussein's HDD - no, they just want the data therein.

ReSpAwN DeMoN
09-28-2002, 12:40 PM
lol that's true I didn't think of that. Pretty much like that kid that supposedly hacked the pentagon and was able to track the current status of every nuclear warhead that america had control of? they took his comp as so I heard and I guess found the data on the HD?

Im surprised that done of you bone head know that if you format a disk 30 times, the data is then completely gone.

thats the number of times reccomended by the governement. 30 formats and your data is gone, gone, gone !!!

but you dont need to do this unless your friend had child porn or some other stuff that will get you thrown in jail for 100 years.

one or two formats will do.

:thumb:

Beefy
10-01-2002, 10:19 AM
actually, if you only format 30 times, then you aren't actually changing the structure on the disk (all the 0's stay as 0's) so you can still read what was previous there.. :rolleyes2

hmmm, what about a low level format. I do not think you can do it with a IDE drive....my SCSI controller will low level format my drive.

Beefy
10-01-2002, 11:09 AM
a low level format is still, in essence, a format.

EDIT: And IDE drives can also be LLF'ed...
