I have a couple of old laptops lying around and want to throw them away, but have been cautious to do so because of privacy concerns of data still on the hard drives. What is the best way to wipe them? Or should I take them out and physically destroy them?
They are running windows vista and 10 I think.
Hammer, then marinate for atleast 30 mins in soya sauce, onion, garlic, herbs, then bbq, eat and poop in 3 different bathrooms across the city. Pro tip, sprinkle with olive oil each side while on the grill.
Depends on the type of drives and your needs.
If the drive is big enough to be used as storage/back, get it out and in its own USB enclosure.
If the drive is either too small or you have too may already then :
- SSD : smash it to pieces with a hammer
- HDD : if you’re sure it’s not an hybrid (in which case the SSD process applies) then you can just fill it with garbage or use whatever “erasing” software out there. I would go for an open-source one.
‘zeroing’ every sector is probably ‘good enough’ for mechanical hard drives.
if the laptops are functional:
boot a target laptop to a windows install disk or usb. at the first prompt, hit SHIFT-F10 to open a command window.
diskpart
list disk
select disk 0
(laptop internal drive should be disk 0)clean all
(this will take time. on an older laptop, up to maybe an hour per 250gb of hdd capacity.)exit
power off.
if they’re NOT functional laptops:
remove the hdd (search the make and model at yt for guides), connect to another pc (via usb adapter) or internal inside a dt. boot to that system’s normal windows, run diskpart from an admin command prompt… do the same as above but note that in this case: IT WON’T BE DISK 0 – be sure to ‘select’ the correct disk
if one of them happens to be an ssd. instead of wiping it (this method isn’t for ssd, btw), get an enclosure for it (as little as $8-10) and use it as an external disk.
Since no one mentioned it: VCR tape eraser.
Basically just an electromagnet that oscillates because it’s running directly from AC current.
With an extension cord you could erase all the hard drives in a computer lab just waving the eraser vaguely where the drives are.
Physical destruction is better though.
You’ve said you’re intending to throw these laptops away, so physical destruction is quickest and simplest.
But, if you’re intending to sell or give these away for someone else to use, zeroing each sector is probably ‘good enough’ for your purpose (as someone else has always said).
If you really want to make it harder, you can use something like the Boot and Nuke bootable Linux disk for the job, as it also has the option of multiple passes, using zeroing and/or binary random shit for each sector. Just grab the free for personal use version.
Use vericrypt to encrypt the drive with a long random password and immediately forget said password
Just turn on disk encryption.
It depends how badly you need that data to never see the light of day again. Most likely, you’ll be fine to erase the drives with secure erase options (where it writes 0 and then 1 to the whole drive, and back and forth a few times depending on settings), but if you really really need to 100% guarantee there’s absolutely no chance of recovery, then you’ll need to destroy the drives physically
There is nothing extremely sensitive on there, but the more time I spend on lemmy (as a bit of a tech noob) the more I care about privacy
In that case, secure wipe should be more than enough
also, if you’re getting rid of them, there might be a charity you can donate them to rather than just tossing them. Idk any off the top of my head, but it seems worth looking into
Laughing at all the Hollywood shit in this thread. A single pass erase (or ATA Secure Erase, if they are SSDs that support the command) is more than enough. Nobody is going to waste time and money recovering data of unknown provenance from a landfill.
HDDs also support ATA Secure Erase, although it will take a few hours rather than the few minutes it would wirh an SSD.
Yes, unless they are OPAL, in which case it’s done the same way as SSDs: throw away the key.
If they are Windows and have Bitlocker encrypt the whole drive and throw away the key. If not get Veracrypt for free and encrypt the entire drive. Once the drive is fully encrypted and has no backup key you can just trash it. If this was commercial use I would then send it to a third party to be certified destroyed.
Smuggle the laptops into the cargo bay of Elon’s next Starship launch.
Here’s a good article from Tom’s: https://www.tomshardware.com/how-to/secure-erase-ssd-or-hard-drive
If you live near an active volcano, dumping them directly into the core should be pretty effective
