Hey/b/

why?

bumboo

(Checked)

burn the harddrive

???

I am too poor to buy new one

it's like 10 bucks. Plus there might be a chance you find someone's nude pics

Privazer

too much really

delete it, then use some sort of disk cleaner or somehting that'll let you wipe free space. I use CCleaner. Don't do it too often or with too many passes as it'll slowly degrade the memory. otherwise, i have know idea and i feel like this option is dropping a nuke in order to kill a deer

I looked at that but couldn't tell if it wiped MFT and NTFS logs but Privazer did.

GLARY UTILITIES. Free, but if you want to pay for it, you get a "deep clean and fix" option that will scour your hard drive clean of every little tiny bit of incriminating info.

copy it and keep deleting copies

WOW like that was so hard to think of OP
I'm being completely serious, don't know what you did or why you wanted to know this but yu have your answer

When you delete something use Ccleaner and check the clean/wipe free space box. It helps for low level recovery.

Pardon me for being such a newfag, but, who the hell is that?

Never mind. Google image search delivered.

Don't listen to any of the anons trying to troll you, all of those ""Eraser"" programs are just malware.
The only actual method to permanently delete files from your PC is as follows:
immediately after deleting the file from the recycle bin, you have to get a magnet and hold it against your hard drive. This will detect any recently deleted files and erase them using magnetic fields.

Hahaha nigga

This is where you go wrong buddy. Anything on a hard drive is cached somewhere. Unless you wipe the HD with a strong magnet

Download File Shredder. Also get Prevent Recovery or whatever that program's called. It scrambles the files you've "deleted".

Doesn't work. Don't you know there literally are high power neodymium magnets inside a hard drive mere millimeters away from the HD surface?
They still can't erase the drive with their vicinity

Put magnets next to your hard drive. It'll pull all the deleted shot out since deleted files have negative polarity

They you can delete it and use software to overwrite all unused space on the drive. Google (or Holla Forums if you show them your boypussy) will help you find something for your OS. However I would not trust this for sensitive data.

If you're willing to get rid of everything but want to keep the drive then you format it and overwrite all data with either 0's or random data. Should be good enough, there's a slim possibility that it's not.

Destroy the drive. Storage is disposable.

This

srm -r -s /*
use that command

tape a magnet to it
burn it
shoot it
throw it in the ocean
throw it in an atom smasher
go TRON in it
get an african voodoo shaman to curse it
throw it on train tracks
furiously fuck it until the files are gone
sit your fat ass on it for 2 years

Any of these options is guaranteed to do something

If your OS is worth a shit, rm has an option for deleting those Porn files.

Delete the file and delete it from recycle bin. Then open command prompt type cipher /w:c (replace :c) with file path to folder or whatever drive you want. That will take a while but it writes random data into it over and over again so its not recoverable.

Bitch, lick this shit up.

Yes.

Why would you want to permanently delete files from your PC user? :^)

This use DBAN, if you get stuck make a thread about it.

You have to burn it to a CD or bootable USB.

you have a SSD or HDD?

Install Gentoo.

heidi eraser (any method will do it, pseudorandom data for speed, gutmann method for maximum paranoia)

Long story short, if you have a SSD, then run a TRIM command to effectively make deleted things unrecoverable, and TRIM also speed up the drive.

For a HHD, use a program like CCleaner to securely delete things.

derp, HDD I meant.

Also, CCleaner can sanitize free space as well for things that have already been deleted. It is quicker to securely delete them in the first place. There's options in CCleaner to automatically apply secure delete when you just clear junk files with it.

...

Overwrite them. Just once is enough. It has been more than 15 years ago that you could still recover overwritten shit in any way shape or form.

Think about it, if it was possible to get data from something overwritten just once, why would that technology not be used in hard disks to increase capacity?

A small, perhaps significant exception is SSDs, it is possible for some parts of SSD data to remain stored without you being able to overwrite it. This is because SSDs have sectors fail, the SSD software (on the SSD itself, not something you can control), will on the fly remap a sector that can no longer be written to on a bit of spare memory that every SSD has. Previously written to data can obviously not be overwritten because that part is failing, so you can't remove it. Although if you have to be afraid of recovery, and you didn't know the previous information, you probably already fucked up at some point.

But really, just one overwrite is plenty.

TRIM should take care of most stuff on a SSD as long as the OS is automatically running TRIM on deleted space. TRIM clears the space and resets the NAND cell so that it can be written to faster.

I've heard the same thing about HDD in recent years. One overwrite is enough. I've read that it is because modern drives have much higher data density than older drives. An old hard drive might require many overwrites, but it's really not needed on newer drives. While it's trivial to recover data that hasn't been overwritten, recovering data that has already been overwritten requires disassembling the drive and special equipment that is very expensive and time intensive to use. Police are only going to go through that effort on international terrorists caliber of criminals.

For HDD, it really shouldn't be recent years, I am pretty sure that any reading of overwritten data was on maximum 10gb HDDs, perhaps slightly more, but certainly not by any stretch recent HDDs. Yes that youth you had is over 15 years ago.

For SSD, what I am talking about is, SSDs have a certain amount of memory, say 120 gigs, but instead of that, they will actually have 130 gigs (made up number, not sure how much bigger they usually are). If a sector on the SSD stops working, which almost always means can't be written to, due to wear and tear, the SSDs internal software will remap the sector that failed to be written to to a part of that extra 10 gigs it had as backup. The OS cannot in any way know anything about this, the SSD does not tell you anything about it, the only possible way to know is if the SSD starts failing because it actually ran out of backup space. But because those sectors can't in any way be written to, they can also not be deleted anymore, meaning that a sector, which possibly contains some data, will be left in the SSD, even if you securely wipe it. The same is kind of true in HDDs, if a sector fails there, it might also mean that no data can be written to it, but most HDDs will actively report sector failure, and have much less of it than SSDs. That said, SSDs might have alraedy improved a lot, but I doubt its fully fixed.

I didn't know how old those old drives were or what the physical cutoff might be in memory size. But that sounds reasonable.

And I know exactly what you're talking about with the SSD. I know they have a reserved block of memory just for automatically replacing dead sectors. But that's not really associated with what I was talking about with TRIM. I know they are completely different functions. I hadn't even put much thought into those dead sectors being recoverable. But even if they are, chances are particularly high that they could get something useful from them, is there? 1 random sector of data may not even contain enough contiguous data to be meaningful. But I dunno. I guess it depends how big the sectors are.

I don't know, I am pretty sure the average size is 4kb. 4kb is plenty for some incriminating stuff if you are unlucky.

Only text could have anything substantial in just 4KB. I doubt they would be able to find anything substantial otherwise. 4KB is probably going to be only a tiny fraction of an image. Anything more complex would be useless with only 4KB.

Hm

Icons of pictures can be smaller, identifying parts of images, password saves in text format, dns logs, encryption keys, windows last opened files and much much more. 4kb is plenty to hide a lot of identifying information in. Of course it would require some bad luck and what not, but it could be used as proof in cases where previously there was only suspicion.

Ahh noo!!!!!

seconding this. the only way to make drives fully unrecoverable is via destroying them. however with programs that write 0's or random data to the drive repeteadlly (some do it up to 30 passes or more of random data) then the possibility of recovery is incredibly remote.

Bitch, what did I say?

You mean like, with a rag?

delete and clear from recycle bin then fill hard drive so their is no chance of it being hidden somewhere as it will 100% be overwritten. also i think flash drives don't save like that.

It's possible to recover some data if you only overwrite it once. Overwriting the whole disk 2 or more times is a surefire way to delete everything permanently.

Bitch, I'm home. Now get sucking.
