how do you usually dispose old HDDs? is pic related recoverable

>>52353396
Yes.

Take the disks out and cut them up with scissors into confetti.

>inb4 OP gets party vanned

>>52353396
It's much easier to remove the plate
(ie see the round circular thing in the middle of the hard drive).
Going to a local steel mill and asking them to melt it.

I just smash the platters with a hammer then melt the pieces in my forge, then recycle the rest.

the platters make nifty windchimes

>>52353396
use DBAN to nuke the thing, then cut it with a chisel while it's running

then smash it into a thousand pieces and throw it into a container

>>52353396
just microwave it for 10 seconds

>>52353396
Dig a hole, put hdd inside, then put a lawnmower over the hole, while bringing the blade lower into the ground. The hole seals the blender of death, keeping the hdd inside the blades. Then put the peices into a beehive and light it on fire

35-pass random overwrite, then dban. Then get a DIY foundry and melt it, if you want to be paranoid

We aren't still using floppy disks you dumbfuck.

If it has no bad sectors and no HPA, or if you had the foresight to encrypt it: One dd zero-pass then throw it in the bin. You're done here.

If it has had bad (remapped) sectors, or has an HPA:

hdparm -I /dev/<insert device here>
# check it's not frozen - if it is: echo -n mem > /sys/power/state # then wake the device, try again - it'll probably be unfrozen
hdparm --user-master u --security-set-pass password /dev/<insert device here>
time hdparm --user-master u --security-erase-enhanced password /dev/<insert device here>

then one dd zero-pass just to make sure, then throw it in the bin.

Nobody, not even the NSA actually investigating al Qaeda, has ever been able to recover past this with an untampered drive. It's completely impossible, even with electron microscope techniques, to get any kind of statistical confidence with modern perpendicular-recording drives (let alone SMR). That 26-pass bullshit you heard of was from ancient MFM/RLL drives, go and ask Gutmann himself if you don't believe me. If you can get anything at all, it's going to be maybe one or two random clusters from remapped sectors: but enhanced secure-erase tells it to wipe those, too.

Note that SSDs fail differently to HDs: blocks either fail erase or become 'sticky' and can't be properly written, instead of becoming unreadable or unreliably written. You cannot securely erase NAND Flash memory, or even NOR Flash; only old-level wide EEPROM. The secure-erase technique above will however tell the drive firmware to at least try to erase the blocks. If you can't do that for some reason, blkdiscard /dev/<device> tells it to trim all sectors by default. That won't be perfect, but it'll do.

You should encrypt confidential or personal data rather than try to destroy plaintext.

You can also take the drive apart if you want handy neodymium magnets. You'll usually find them in there, being used to keep the heads from crashing into the hard disk if it suddenly loses power.

How would you possibly know this? It's only been in the last decade that the government has even officially acknowledged what the NSA does. They aren't exactly know for being very public about their inner workings.

NOT SUSPICIOUS AT ALL

>>52353396
Heat it up to around 1000K and it will lose all magnetic properties, permanently removing its ability to store any information.

stick your dick in it

>>52354695
The government having access to technology decades ahead of the rest of the world is mostly a thing ofnfiction. The last time that legitimately happened was WW2.

They have the most money to spend so they have the nicest things, but the ability to recover data off a disk after a wipe like that isn't something you can buy. It's not even technologically limited, its just physics.

>>52355188
It's less suspicious then ordering an actual tiny ass smelter for it or fucking making thermite.

Autisim never seeses to amaze me.
>My face when you already don't own a small melter for used HDD's.

I just write all zeros on to the fucker.

Can someone link me to a source (or explain) how data can be got out of a completely zeroed drive? Because I've heard a few people say this isn't enough.

>>52355277
looks like OP already did that

You're autistic alright you can't even type properly.

>>52355826
Typically heating something up that much doesn't leave smoke residue. I'd guess that he just tossed it in a regular fire.

>>52355660
It can be cached or old magnetic signatures can give it away

fbi doesn't care about your dolphin porn.

>>52355876
Not my native language so i don't feel bad.
And don't say buying a small smelter for HDD disposal is not autistic. Or going to steelmill to melt them. CP or not, still far better and easier ways to dispose of them.

Take it to the local gun range
