can anyone recommend some good software for erasing a hard drive beyond recovery. you know a police on the way so burn everything kinda deal.
there,s a lot of different ones out there and the last thing i need is a false sense of security from a crappy program
thanks

I would suggest active killdisk. i believe it does a 7 pass erase and write over that even the Department of defense can't recover your data

Go with DBAN: Darik's Boot And Nuke
http://www.dban.org/
Bootable CD that has several different options for a wipe including 0 fill, random, DOD (3pass), DOD (7pass), and GUTMANN (crazy amount of passes).
Really, if you're doing something that you don't want to get caught at or have data you don't want read, it's a better bet to have full disk encryption in the event you get popped. Turn off the computer with a power strip at your foot. Then pray they don't freeze spray the ram and try to analyze it for the encryption keys in memory.
Checkout http://www.truecrypt.org/ for virtual encrypted disks and full disk encryption.

BCWipe also does a DOD 7 pass erase.
Never heard of DBAN though. That sounds really good.

Just so you guys know, there's no way to fully remove data from a hard drive short of melting it with thermite.
There have been reports of drives that have 7+ wipes on them, thrown into a river, recovered years later and data taken off them.

I would take a sledgehammer to the drive and pulverize it into pieces small enough to flush.

Thats not true. You need to use a SEM to look at every bit.
Consider if what you said is true, then a hard drive could theoretically hold an infinite amount of information. Even more than the entire universe can hold. But a hard drive is a subset of the universe, thus a hard drive cannot hold an infinite amount of information and thus data can (and must be) removed from a hard drive.

Or drill multiple holes straight through the drive. I work with computers daily for a living and destroy many hard drives. We have recovered info off drives that have been run over by cars, hit with hammers ect...

Im not sure how running over with a car or hitting with a hammer would destroy the data? I would expect it not to.

fdisk, it's been built into dos/windows forever.
the F stands for format.
OR you could use diskpart.exe if you run a newer version of windows.

Worst advice in the thread. Formatting doesn't get rid of data, it just deletes partitions. All that data is still there and fully recoverable.

If your concern really is the police, you would be much better off to use TrueCrypt full disk encryption with a dummy operating system as a smokescreen.
Im not sure how much time you think you are gonna have once they start breaking down the door... Doing multiple wipes will take hours. Having your disk encrypted ahead of time would be much better.

Anyone confirm/rebuke a powerful magnet on hard drive wiping everything? Doesn't it just pretty much set all of the data to 0's?

Even if a powerful electromagnet did flip all the bits to a one or zero, if someone REALLY wanted to read the data, they could magnetically analyze the drive to reconstruct the contents.

You forgot the most important question.
What is a good program you can use to recover lost data on a hard drive?
Ya know, so you can test out the effectiveness of these programs listed.

You basically need an electron microscope to reconstruct data that has been wiped over. After a couple wipes, an electron microscope wont even work.
(also consider the size of modern hard drives, and note that each bit needs to be scanned)

So what you guys are sayin is that data stays on the disc after it has been formatted
Does the old data disappear as I put new stuff on my hard drive?

Dariks boot and nuke, will wipe your hard drive and rewrite it with nonsense 32 times over which is up to the department of defense standards.

The evidence that you visit sites like this exists on the web and with your isp. No amount of destructing to your hard drive will change that.
If I was as scared as you about visiting web sites, I would stop visiting the sites.

No, no fucking no. I mean you could. But no.
When you delete data on a drive it isn't actually deleted. Those sectors the data occupies are flagged as empty- the data remains in place however. When the time comes to write new data, the old data may or may not be overwritten, it just depends if it happens to be chosen as the empty space to be occupied. Software can skim a hard drive, find the files which haven't yet been overwritten, and recover them. As you can imagine, you end up with mixed results. Some files come back whole, some partial, many corrupted beyond use.
Thus, the amount of time since deletion and the amount of use both play a central role in if the data is erased or not. There is of course software that can clean your tracks also.
However, as previously stated, web servers and ISP's keep records too, so you might as well just revel in the fact the internet is HUGE and that unless you win the shit-lottery, you'll probably be fine.
Also, fucking molten lead, wood chippers? For fucking serious people?

Checking your reading comprehension. A wipe is writing over data, not flagging as deleted. Just about everybody in this thread knows the difference.
An electron microscope or similar technique is required to recover data that has been wiped/written over, and it can only recover data a couple of wipes old.
