Is this the best way of disposing of old HDDs?
I just cracked open this HDD from an old laptop (it's a Western Digital hdd), just out of curiosity, and discovered the platter shattered as if it were made of glass. Even though it feels light like plastic.
The safest way to maintain the privacy of your data is to destroy the platters, take the pieces of broken platter and soak them in some type of flammable fluid, stab an NSA agent in the neck and let the blood soak into the grooves, and then light it on fire.
Only the heat from burning NSA blood can permanently erase data from a hard drive. Not even melting the disks will work.
Its often coated silicon or a metal alloy both are very common its impossible to say what platters are made of since it varies so much.
A propane torch would do the job very well I imagine.
Yea Laptop 2.5s Shatter. They're too thin.
Thicker 3.5 platters can actually bend like tacos without breaking.
I usually just hammer a screwdriver through them when requested to destroy them. If not I zip tie them together to make Platter Garland. Got about 30 feet currently.
It was DEFCON, and there were actually two separate talks about this topic:
TL;DW: it is nearly impossible to destroy harddrives
that will make it unreadable to almost anyone but those shards still have magnetic data on them and even a small shard is large enough to hold a lot of data.
if I were to get every shard I could glue them onto a normal platter and use a single sided head to read that data again, it would be corrupted but that corruption would be easy to sort out due to error correction data that would still exist. I could recover parts of any file on your system and probably a lot of complete smaller files.
NSA or private firm would be able to get almost everything. private firms charge over 100k for these types of things especially if the platter is so damaged that they have to use an electron microscope to recover the data (which is a thing and can recover data that has been overwritten more than 2-3 times!!!! HOLY SHIT).
you can nuke it in an old microwave or what I would do is put it in a fire or oven at high temps.
oh yes that's it, is it too dangerous? would a mask like this and some anti-acid gloves be enough? doing it in the open of course.
no it will kill you in an unimaginably painful and horrific way.
if these fingers look funny to you its because the bones inside them have been dissolved by HF acid.
Nobody is going to find your cuck and cartoon porn or care if they do, you should be flattered to think someone would actually rummage through the trash trying to recover a shattered platter full of useless shit on your drive. Anyway all of your data is already mirrored on an NSA server
Well, I didn't plan on destroying it. I just had this HDD from an older laptop which failed, so it was replaced.
I got curious, so I thought I'd crack it open to see how the platters look like before I throw it out. I had no intention to destroy it. I discovered the platters simply shattered to pieces, before I could get to them. Must have been all those deformations taking place, from the tools I used (some pliers and a screwdriver).
Yeah, I tried that first, but I just don't have any screwdriver that fits that type of screw. So I ended up using a heavy-handed approach to satisfy my perverse technological fantasy of seeing the HDD platters naked.
>Which set do you recommend?
One with Torx bits. I've had this for several years now and its been great for getting into small electronic devices like hard drives and phones.
Guys, the most secure way to dispose of a hard drive is to use full disk encryption from the start. That way, you don't have to bullshit later on, just toss it and you're good.
Fuck, I actually do something similar with old flash drives. Break each chip into four pieces, each go in a different batch of rubbish, sometimes in public bins.
I'm bored a lot, and like to pretend I'm James Bond.
1. Take the drive apart
2. Smash and dispose of the case
3. Burn the platters
4. take the burnt platters and put them in a blender until almost a powder
5. Separate the powder into 4 groups
6. Bury each group of powder in 4 different locations, each at least 2 miles away from each other.
Done your drive and data have been successfully destroyed.
The most effective way to dispose of hard disks is degaussing. This requires an absurdly strong magnet. The machines run about 10,000 USD. If it still works a one-pass of zeros is sufficient on any hard drive made since the early 2000s.
To be completely safe
>nuke the hard drive
>use power drill on drive
>smash drive with hammer and take some of the disc parts and dump that in a separate garbage bag
Hard drive has literally no chance of being anything more than scrap at that point
Just use a shotgun like every redneck ever. Coincidentally, skeet shooting with old CDs and DVDs is pretty guud.
The likelyhood of the anyone actually recovering data from a broken platter, is slim to none. For anyone to rebuild the platter itself, would take MANY years and even then there would only be only bits of sectors that would be recoverable.
I have worked with HF. I am glad i no longer have to. My dad worked with it and nearly died in a lab accident.
Under no circumstances whatsoever should you ever handle HF without a full set of proper lab gear, in short driving distance to a hospital, with calcium propionate on hand.
I'm no chemist, but it won't effectively dissolve many hard disk platters, just clean them (it might do a number on the vitreous ones?). The steel bucket, however, was a bad idea. You need PTFE plastic, in a fume chamber, because HF fumes will fuck you up and you won't even know about it.
One zero pass with dd, or better still, an ATA Secure Erase Enhanced (because of reallocated sectors) will do the job. Don't dick around with dangerous chemicals.
>passtime of mine is to buy old USB sticks and hardrives from fleamarkets and garage sales and see what kinds of data I can dig up off them with an assortment of various programs
