Oh god i thought this was HowToBasic
dd if=/dev/urandom of= and your’re done…
+Marco Tedaldi I just tried on my machine and for me only /dev/zero provides output, /dev/null just sinks data.
+Marco Tedaldi No it doesn’t. /dev/zero is source, /dev/null is sink. Try to read /dev/null with dd and you get nothing out.
+Dmitri Not substantially, not at a rate that’d matter with HDD IO.
If you do this on an SSD… well forensics can still get data off it, wear leveling and such.
Also overwriting everything with zeroes might get forensics enough hints because you’re either changing a cell or leaving it as is, with urandom it’s at least somewhat random.
Not to mention encrypting and throwing away headers is always the superior way to delete files. With luks you can even back them up with plausible deniability!
+Marco Tedaldi No it doesn’t. Trying to read from /dev/null returns immediate EOF (0 bytes read).
Why not /dev/fuck/
So RedKey USB is just repackaged DBAN. I runs whatever HDD erase method you want, just like DBAN. It didn’t try to secure erase the SSD like a manufacturer tool would, at all.
+sisbrawny A regular HDD doesn’t have a secure erase feature. You have to overwrite the data on the disks, which takes hours to days.
+Solkre I used the secure erase feature built into my HDD. No downloaded software.
+sisbrawny What make and model Hard Disk Drive was it? I’d love to find one that could somehow do that! It would still have to take the time to write data to the platters.
+Solkre Hitachi 5K750-640. Now that I think about it more, I did use Parted Magic from the Ultimate Boot CD to do the secure erase. But it worked. I think there was a choice to use onboard disk features.
+Solkre I don’t understand how Secure Erase can be better than writing every sector. If it doesn’t overwrite every sector, then how can it be “secure”? If it *does* overwrite every sector, then it will cause just as much wear and tear as regular writes.
I wipe my PC every 2 weeks using soft cotton 🙂
They had us in the first half, not gonna lie
I gotta say, you had me on the first half
Sabith Pkc Mnr you must be really ashamed of the forensic cookies all that kiddy animal beastiality porn you surf leaves behind. REPENT SINNER !!! oh you mean with a cloth ahhahahahaja diabolical Hitlary laugh…
Sabith Pkc Mnr ?
Every two weeks ? Lol ?
What’s the quickest surefire way to destroy data permanently? Hammer? Microwave? Fire? How thorough are these methods against a professional data recovery service? For research purposes.
high enough heat would likely fuck with magnetism. Cut it into pieces, bend it, bury it in your yard.
Just throw your hard drives into a hot molten lava. Problem solved.
You are supposed to say “Asking for a friend”. 😉
Workaround: encrypt everything with a looong passphrase and non government software. Then: don’t tell anyone the phrase.
Alternatively get a small but fast SSD and put all your important stuff on there.
Example:
the Samsung 970 EVO Plus 250 GB has up to 3,3 GB of write speed (samsung benchmark). Because of that one pass is 76 seconds.
Execute “deletesystem32.exe”
*2 hours
NCIX should have used it.
ohh snap…
They didn’t have $45.
+Fredrick Tuso DBAN is free
+the mre nerd yeah… And that doesn’t have anything to do with the comment we replied to. We were roasting NCIX for their data breach and bankrupcy, not chatting about freeware alternatives.
I’m awfully sure I’ve been using DBAN longer that you have and I know it’s free, it isn’t much use for enthusiests anymore because the free version doesn’t support SSDs but I’m sure the NCIX servers used spinning drives.
Oh no Linus! MBR is only 512 bytes and does not contain file system files, where are your fact checkers?
the fact checkers are in a vox media office. just kidding i dont think they would use these competent people
Has Linus turned into Kellyanne Conway??
1:34 i thought the video was brought by RAZER
I started thinking Razer made RAM
Yup, me too and checking his phone to see who the sponsor is? Segways be damned
RAZER MASTER RACE ༼ つ ◕_◕ ༽つ
+Athaariq Ardiansyah You can see Razer and Blackwidow for over 1 second
Urm… File information is neither in the MBR or GPT. That’s just where the partition information is stored.
It’s either the FAT (for FAT-Filesystems) or MFT (Master File Table for NTFS) on Windows…
0:41 “entry for the file” wat … MBR and GPT contain entries for partitions.
Linus Tank Tops
shows how technical this tech tips dude actually is, I mean, I don’t mean that in a bad way, but maybe don’t take his advice on system level stuff for full
+Serenity Laboratories Probably right, Linus is quite tech savvy, but he is in a really wide way, he has to know a lot about a lot of different areas, for this kind of super deep hardware and software topics, I think Anthony is the most prepared one in LMG at this point
+YOEL _44 i mean this is not really super deep
if you want super deep how to actually destroy hard drives in a hurry, watch this, it has explosions, hackers and thermite!

No a prt
6:11 This is looking suspiciously like a DBAN skin. The thing about “for HDDs but not SSDs” earlier in the vid doesn’t add up with all these different “government” wiping methods that DBAN definitely also has.
especially since Linus said in the beginning of the video, one shouldn’t overwrite the data on a SSD, because of unnecessary wear and then doing exactly that thing based on the time it took. using the secure erase function of a SSD should take a couple of seconds, not hours.
Plus deleting a file on a SSD with working TRIM it is usually enough to destroy the data. Linus explanation of deleting files is actually only applicable to HDDs.
The usual case of paying more for some proprietary product that does less than Free software that is already available.
No man should wield such power…
No, MBR and GPT have nothing to do with file records. That’s in the file system, not the partition table…..
take my upvote
I think they were mixing it up with the way quick formatting works, that just erases the partition entry in the gpt/mbr
They don’t, they are simply the structure of how the drive is partitioned and how the corresponding OS will be installed on it.
Try on your petabyte storage?️.
no
80 years later
In the mode that does 33 random passes and set to run a dozen times
Recuva doesnt actually work that good, EaseUs works way better in recovering lost data
And photorec works even better than Easeus.
It especially does not work on SSD’s. Flash storage once erased has no leftover files on it anymore. Thought they know that :O
“Wipe any PC in 2 Minutes!”
*Wiping takes 2 and a half hours*
Linus is a time traveler that’s why
Clickbait intensifies.
Just buy the USB Killer and wipe your pc in a second.
+Plasmaboo woooosh
+Plasmaboo this will damage anything connected to the computer if the computer doesn’t have the usb ports aren’t protected
+DayVElChingon WRONG, there are several overload protections between the USB ports and the drives. I tested that on several old laptops that went into recycling
Plasmaboo it’s as if something just *wooshed* past your head you know, reminds me of a joke
Wouldn’t fry the storage medium(s) leaving the data potentially 100% recoverable.
*_Don’t try this at home, school, office or anywhere._*
