So I bought two used ssds and decided to use recuva to see if

I read the thread many times OP, and I couldn't find the link to the mega upload with all the stuff you found.

Parted magic, I have heard, works well. Or the built in SSD utility from the manufacturer.

>>60798783
they were oem samsung ssds, sm841. AFAIK is basically a 840 pro for oems.

>>60798527
do a single run of all zero's. Command is simple in linux or windows.

>>60798842
will this work for both mechanicl hard drives and SSDs?

>>60798875
yes. Don't worry about mutiple passes or any of that bullshit. Its literally all Meme tier info from 30 years ago.

If you're interested in this, read up on NIST's documentation: http://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-88r1.pdf

This document isn't too technical, and you can skip to the section where they just talk about drives.

>>60798927
I was reading some info that basically said that it's better to write random numbers instead of zeros.

But don't understand why

>>60798815
Samsung has the magician software.

>>60799039
So in that case you'll probably end up with a sheakspeare play waiting to be read once you dig through those numbers

>>60799039
Overwriting with one pass of random data is the same mechanism as encrypting with a one-time pad.

>>60798527
the only firesure way is to drill then microwave the mofo
Then throw it at the bottom of a body of water just to be sure

dd if=/dev/urandom of=/dev/sda

That should be more than enough on modern hard drives, especially SSDs, but if you're paranoid use

srm -G /dev/sda

which uses Gutmann's deletion algorithm, or on an SSD use secure erase https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase

Any other answer is wrong.

>>60799642
Not if you're using /dev/urandom which is what you'll be using when erasing hard drives. It's more efficient (inherently less secure). It's the same if you use /dev/random.

>>60802707
You don't understand how hard drives work, do you?

>>60802829
I saw it on Silicon Valley, a show about tech nerds, so it must be true

the character was a h4ck0r too

>>60802810
op here, I don't understand your post, pls explain.

>>60802845
Good show but has a lot of inaccurate moments.

>>60802847
https://stackoverflow.com/questions/3690273/did-i-understand-dev-urandom

/dev/random requires lots of entropy and often "blocks"; runs out and waits, where /dev/urandom doesn't.

>>60798527

dd if=/dev/zero of=/dev/sdx

Should do the job

Just replace the content with memes, then delete it

>>60802936
But most memes aren't really /random/ and may be vulnerable to RNG attacks since the entropy poole isn't really /random/

>>60802969
what is really random besides atmospheric noise?

The US Department of Defense does at least three passes over the drive: overwrite entirely with zeroes, then overwrite entirely with ones, then overwrite with random data. Overwriting with random data may be repeated up to 5 times making for 3-7 total passes.

That said, while floppy disks were vulnerable to data recovery after one all-zero overwrite, modern drives are not. One pass should suffice.

>>60802982
Me.

*Holds up spork*

>>60802750
will this kill the disk?

>>60802906
or this?

>>60803334
Well if by kill, you mean make it unusable then no. /dev/urandom will fill it up with random data and /dev/zero will zero it out. You can always make a new partition table and use it afterwards.

>>60803363
ok thx!

SSDs have loads of hidden storage it marks as unavailable when the write limit gets close though?

They are pretty much impossible to wipe save a complete destruction

>>60803022
Kek :3 ^_^

>>60798527
tell us about this guy's life

If you're worried about writing so much data to an SSD, you can use the secure erase command. Arch wiki has a guide. (which you can do on any Linux, btw)

>>60803590
nothing interesting tho, the ssd might have been from his college laptop

This I just gathered from a quick glance, and it was really shocking how you can make a profile from someone you don't even know with so little information.

I got bored and stopped digging through.

choose one

Why would you sell any hard drive?You cant completely clean it without phisically destroying it with a hammer.

>>60798527
For hard drives, just write the whole disk at least once with zeroes or random data. You can do it multiple times with different types of data if you want.

For SSDs... You can do the same thing and it will make it look like the disk has been erased, but SSDs are about 25% bigger than they claim to be on the packaging and that additional storage exists internally and is used for making writes to the disk. It regularly contains entire unencrypted sections of filesystem even after you think the disk has been wiped. Fortunately it's only accessible by dismantling the SSD and accessing the pins on the flash chips directly, but still, it's there. If the SSD doesn't support some kind of secure erase command there is functionally no way to wipe the bloody things properly, just put them in the microwave.

>>60805811
If it's used for making writes, why won't it contain only zeroes after writing the whole SSD with it?

>>60803879
Do you consider shooting lasers evidence of it being able to go to space?
