Hello /g/, has anyone here ever fully wiped a drive?
I'm overwriting a 600GB drive with 0s now, and i kind of need to kill the time.
Let's start a discussion.
Why did you wipe the drive?
What was on it?
What method did you use?
How big was the drive and how long did it take?
Was it your main drive?
The drive i'm wiping was obtained from someone else and i am usingsudo shred -zvn 0 /dev/sdato wipe it on his request.
It's 600GB and idk how long it takes.
There was a pruned windows install on that had boring files related to school projects of more than a decade ago.

Paranoid pedophiles wouldn't post on /g/ about wiping their drive.
This is the most widespread /g/-meme.
>>54363996
I used to all the time,
> why?
because windows would act up if I didn't, i guess that means i probably had a bad drive.
> method
tried several, format c:, dban, just whatever.
> I would count the seconds it would take to do a single % point, and then multiply that by 100% and then you know how long its going to take
> main drive?
yes, ive had two catastrophic data losses on drives and that made me paranoid and never stored data on a drive that was connected to a computer again, data is stored and unplugged and made copies of in different locations for the purposes of backup
>>54364148
Whatever you say, pedo.
>>54363996
>Why did you wipe the drive?
feds were coming
>What was on it?
secret data
>What method did you use?
microwave
>How big was the drive and how long did it take?
terabytes, 30 sec on high
>Was it your main drive?
yes
>>54364194
It sounds like you now know what the shittiest drives are.
To fight dataloss you can use mirror volumes or forms of RAID (or mah insecure cloudstorage).
>>54364196
Back to /b/, vermin.
>>54364229
Please tell me you said something on the lines of "who's hungry for some cheese pizza?" when the microwave said *ding*
>>54364196
>wanting privacy makes me a pedo
ebin
lol, cipher /w is more thorough than shred.
why is this the case?
Encryption plus single pass equals no fucking way you're getting data back
>>54364239
>To fight dataloss you can use mirror volumes or forms of RAID (or mah insecure cloudstorage).
true, but i'm a poorfag neet. only things i store now are just family pictures and music files nothing else is worth storing for me.
I preach it, don't store personal information on your computer, it's risky than ever before also, with cryptolocks and catostrophic hardware failure, also the weird 1 in a 1000000 chance that you can have fire/theft/water damage.
Spend $100 get two 1TB drives, store your shit in them, store them away from your home, in separate places. If you have more money, buy three tape drives and a couple of old laptops, store them along with your data tape backups and you're guaranteed full recovery for a long time.
>>54364266
>thorough
I don't believe in an afterlife for "incorrectly" wiped bits.
One pass with all zeroes should be enough, and if it's not, i should have a serious talk with the previous owner about the files on it that someone is so interested in to do extensive research on how to recover it.
>>54364262
No one is interested in what you store in your drive, there's no reason to do this kind of thing unless you're hiding something illegal.
>>54364245
U mad, fagget? :^)
>>54364315
Sure NSA shill, thanks for your shitty opinion.
Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
>>54364315
>hiding something illegal
My gf nudes aren't illegal, just as my online banking login, my ssn, and other private data.
If you don't feel like hiding them, could you share yours?
If you say no, then you're a hypocrite.
>>54364301
>store them away from your home, in separate places
Nobody's doing that stupid shit.
>>54364313
lol no. the job is either done or it's not. data recovery happens for more than law enforcement purposes, including the exact opposite.
making excuses for half-assing a job doesn't mean your logic is sound.
>>54364315
>>54364349
Exactly, you have "nothing to hide" after all. So if you so freely want to share with third parties, just post it here.
>>54363996
>Why did you wipe the drive?
TC suggests that you wipe your drive before it can be encrypted.
>What was on it?
Movies. I wanted to encrypt it though.
>What method did you use?
TC did it for me.
>How big was the drive and how long did it take?
2TB, 1 day
>Was it your main drive?
No.
>>54364350
You could exhange encrypted backup drives with your bro.
>>54364315
>No one is interested in what you store in your drive
It's not about someone being interested.
It's about knowing that no one on the planet can ever access your HDD. Perfect privacy. It's a nice feeling.
>>54364252
kek
>>54364350
Pretty simple really, one drive in your car, one drive at your parents place.
>>54364361
The cost of recovery exceeds the value of the data by a huge factor.
I'm just wiping it because the previous owner request it and i don't mind.
>>54364425
Or just keep an encrypted backup online, like a sane person
>>54364349
Not wanting to show your files is one thing, being mad and encrypting every file in your drive because 'muh privacy' is another.
Worse yet destroying your drive or filling it with zeros 100 times.
Again, no one is interested in your "GF" nudes and no one will ever attempt to get them, no matter how /g/ autists tell you that everything is a botnet.
>>54364362
>so if you so freely want to share with third parties
No, i don't, not worth the time and energy, and i don't have a reason to do so.
>>54364464
Then stop being a fucking retard already you annoying bitch.
>>54364460
It was an example, my data was never on the drive.
The previous owner requested me to do a secure wipe.
>>54364456
>Or just keep an encrypted backup online, like a sane person
why do you need it encrypted?
>>54364486
That argument is not suspicious at all. Better plug in the microwave son, they know now.
>>54363996
I dd'd it a few times and put /dev/random on it, I don't do pleb mode 0's
wipe it to wipe it. os's get bogged down no matter what you do. i reformat every 3-4 months.
>>54364361
one pass is enough
if one pass doesn't get the data then two won't either, because the problem is with the firmware. if you think otherwise then you don't understand how HDDs work. there is no "ghost space" for shit to hide
>>54363996
>Why?
Was gonna give one of my hard drives to my buddy who's in IT, to be replaced with a primary SSD and my NAS.
>What was on it?
Had passwords saved in text documents (because I was stupid), my resume, PDFs with my social security number on it, etc. All from several years of usage. Even if I formatted via windows several times, I could recover most of that stuff with simple software, hell some of my shit from 2009 was available.
>What method did you use?
I used DBAN, DoD 7-Pass Method.
>How big was the drive and how long did it take?
1TB, I think it was 5+ hours
>Was it your main drive?
Yes
>>54365182
Speaking of SSD, How do you wipe an SSD?
I read it was as simple as deleting the encryption key to make all the data useless.
>>54364315
I think the last time I said "I have nothing to hide" I was around 13. I still have nothing illegal, but I certainly have things to hide.
>>54364115
It's better than destroying hard drives. Many companies and civil services are doing this.
>>54365399
Don't mind him >>54364115
He doesn't know we live in free countries where you can do stuff like this without being suspicious
>>54365399
Yeah, I worked as IT in a massive company that will remain unnamed, they have red data up the wazoo and never did this, encryption only. Going to such lengths as an average joe is suspicious as fuck.
>>54363996
Sure, I do it all the time in my job. I'll talk about a larger one we did recently.
>20TB NAS under RAID10
>Wiped because it was running on an old QNAP box with redundant state polling data that gets fed into R and SPSS, then spat back out and stored, languishing for god knows what reasons. Drives are WD Yellows < 4yr old, so we figured we'd clean them up and move them to another group's gear.
>Polling and business data, along with some analytics, stored in a variety of DB and raw data formats. Some files are just gigs and gigs of xls or csv.
>4TB x 5
>We used DBAN, good old "DoD Short."
>I think we clocked in at about 36 hours - the QNAS itself was churning at five times the estimate, so we said fuck it, removed them, and commandeered a Xeon box to get it done.
Smaller drives < 2TB in workstations, we just zero them + image and move on.
>>54366043
What's red data?
An expression like red tape?
>>54364460
>100 times
>one whole hundred
>>54363996
I wipe any drive I get that isn't new.
I do it simply because if there happens to be anything illegal on it, or anything like SSNs that I really shouldn't have, I'd rather not know about it and just get rid of it.
How depends on what's most convenient. If there's a bunch of drives I want to wipe, I connect them all to an old machine and use DBAN. If it's just one or two I'll use USB adapters. If I'm using Linux, I do shred with one random and one zero pass. On Windows I tried a couple random disk wiper utilities, then found that TrueCrypt volume creation is faster and has the same effect -- overwriting the drive with random data. So sometimes I just create a whole-device TrueCrypt volume and roll my hand across the keyboard to make a password.
>>54364460
>no one is interested in your "GF" nudes
What about the threads like "hay /b/ I found a phone and there was some nudes on it, halp me recover them and I'll post them"?
>>54364480
hot damn this kid is mad
go back to Facebook, faggot.
why are you even using an anonymous site?
in fact, if you don't think privacy matters, post your name, address, credit card number, phone number, and last 4 digits to your SSN.
After all, these are just ordinary information you give to third parties all he time. So post them here, or else you're a pedophile hoarding CP.
>>54364540
Because not everyone likes their pictures of family and password database readable from other people.
>>54363996
sure i do it all the time.... The CEO of a small bank let me have his SSD on the condition i wipe it. So i used hdparm to clear the cells... I used DBAN and the UNIX dd utility to DOD old mechanical drives and if they can't be repurposed (<7200RPM or <500GB) I hit them with a hammer until my arm gets tired.
If i sell an old computer I will give a windows license and a clean HD (will install for them if they ask). This shows they they are inheriting a fresh PC without the risk of it being full of malware or illegal content.
Why go through this?
A: It's easy
B: The extra data security is worth it. I don't want some third world kid digging up an old drive with important IP (from me or my employer) then blackmailing me with it.
>>54365266
You secure erase it.
>>54365266
clear the cells
For Windows and Mac there is usually a disk utility program that comes with the drive that will pass the cell clearing command to the drive controller.
for *nix there is hdparm which does essentially the same thing but isn't graphical.

>>54365123
You suck at basic maintenance then.
I've been on Win8.1 for nearly 4 years now without a single format or wipe. It's been as blazing fast as when I first started, and I usually leave it on for months at a time.
>>54364540
>Data hosting company gets compromised
>They have access to all your important shit.
>Wanting employees snooping around your files for shits & giggles
Plenty of reasons.
Of course, uploading giant encrypted blobs of data isn't really a feasible option unless you have fiber speeds.
>>54364115
Nice try, nsa
>>54365123
Are you one of those people who turn off all unnecessary services, like the idle tasks and periodic defrag?
Because that's Windows preening itself and keeping itself from becoming a slow mess.
>>54366731
If you have an SSD(Which you should, it's fucking 2016), then defragging is pointless. In fact, it's harmful for an SSD.
>>54366853
And in Win8.1, running defrag on an SSD makes it TRIM all unused regions.

Classified data, almost as dramatic as your eyes only.
>Why did you wipe the drive?
Confidential information that a compatriot wanted to take from me
>What was on it?
Incriminating evidence of an all out crazy weekend that may have ruined multiple relationships and gotten someone fired from their job
>What method did you use?
Melted it at 1400 degrees in a charcoal furnace
>How big was the drive and how long did it take?
260gb, took 2 minutes for the platters to become liquid
>was it your main drive?
no
>>54366426
Not the guy but not having your hdd zero passed and your shit encrypted is not the same as tossing away your personal information to public websites. Your argument is shit and you are far too upset for something this simple.
These are tells of having something to hide(tm), better get double sheeting on that tin foil.
>>54363996
>Shred
Lel
>>54367333
And what's wrong with shred? It works.
>>54367403
>It works.
Only on sectors that are not labeled as bad, and it doesn't even touch SMART data.
>>54367449
Same as every single other software based data destroyer program. Only more thorough way is the ATA SECURE_ERASE command, though that's really opaque and doesn't give any sign of what it's actually doing inside.
Also why on earth would you want to wipe SMART info? Does it really matter if someone finds out that your HDD was powered on for 5000 hours and has high spin-up time?
>>54367565
dd doesn't skip bad sectors you stupid nigger
>What method did you use?
UBCD > DBAN
It's been so long that this is the only question I remember the answer to.
>>54367650
It skips remapped sectors on the disk, which is what I assumed you meant. Shred /dev/sdb will skip nothing that dd can get.
>Hello /g/, has anyone here ever fully wiped a drive?
Of course. I do it as a standard procedure when getting rid of drives when I'm not very sure indeed that it doesn't contain anything sensitive.
>What was on it?
Anything, really. It doesn't matter, it's a wise thing to do no matter what data is on there.
>What method did you use?
ATA secure erase, usually. It's basically the only method that will reliably wipe the damaged sectors too (as much as possible). This is usually needless paranoia, but it doesn't cost anything extra so why not.
>How big was the drive and how long did it take?
Modern drives can usually wipe something like 200GB per hour.
>>54366484
>>54366676
If you encrypt your backup drives and at the time you try to use them they happen to have developed bad blocks of data, do you lose just that block of data or do you lose all the contents?
Like ... with a cloth?
>>54368275
Just the blocks of data. You shouldn't ever have to worry about shit fucking up because of the encryption.
The only bad thing that can happen is if you lose your password/keyfile. I've been using encryption on all 20 of my drives for over 7 years now without a problem.
>>54363996
Is it finished yet?
>why
Because the customer asked me to
>what was on it
All my customers have really vanilla shit when it comes to porn, never anything interesting
>what method
Corporate gives us special drive wiping software that as far as I can see isn't available for sale
>how big how long
Idk man I plugged it up ran the software went to go take a shit and when I came back it was done
>was it mine
I'm a pretty simple man I have nothing of value
>Why did you wipe the drive?
fbi knocking on my door
>What was on it?
cp
>What method did you use?
turned off the computer
>How big was the drive and how long did it take?
idk how big, took maybe 2 min to shut it down
>Was getting caught part of your plan?
of course
>>54365123
>using windows
lolololololololol
>>54363996
ATA Secure Erase
>>54363996
technically no wipes are really secure.
even 50k writes on the same bit can be reconstructed with the help of neighboring bits and depending on hard drive quality.
the only surefire way to wipe a hard drive is to destroy it.
the mit did some case studies some time ago where they were able to reconstruct and recover original data on a hard drive that had been " securely" wiped by overwriting every bit over 2m times.
>>54369405
how is that possible? i cant imagine that
>>54364262

>>54363996
We used a bootable WipeDrive Pro CD on the computers at work (back when I worked with hardware). Never anything over 1TB at that time, I think we used some 3-pass method. Bank and customer identifiable data, had to be sure it was toast.
>>54369405
Sauce? I'm really interested in reading about this.
Thought 40-pass is enough to hide the passwords.
Keywords? Paper name? Link?
Whenever I want to wipe a hard disk I just order a MRI scan.
