@ghostsarespooky "under" the rubber feet? Jesus that must have been it. I did all the other stuff.
@Nonya_Bidniss Yep. Turns out I still have this thing, and I've swapped memory and disk on this thing so much the feet no longer stick. Just the rear two, not the four like I had initially mentioned.

I've been physically destroying several old hard drives and prepping a pile of old electronics for recycling. The HDD in this old acer palmtop was too hard to get out. I couldn't even figure it out. So I found this very old software to supposedly wipe it. It's fine, I only ever used this thing to tinker with Arduino anyway.
@Nonya_Bidniss old HDDs are actually securely erasable, unlike SSDs where it's rather a "Trust me Bro!" kinda thing.

Old HDDs are not be securely erased unless you do it like US navy erased them.
Dip them in acid
Some drive tracks can be read on the "outside".
By state actors mainly.However, both HDD and SSDs can be permanently erased in a microwave

@n_dimension @kkarhan @Nonya_Bidniss there are scripts that nuke the whole OS and Kernel and DD, just 1 script to run on the pc .
Mr Robot used the chip for a microwave and pierced a hole in the HDD, in the movie whoami they used acid indeed with a mask on.
But just 1 script and you can overwrite the hdd or SDD or/and nuke the whole OS> I wish them good luck with that recovering anything. -

shredthat do the repeat overwrites with random data, 0s & 1s.- Just iterate over your physical drives and you should be good
- That does work fine, and is kinda essential with shitty hosters [i.e. Hetzner] that tend to not even replace/delete the vHDD of their VPSes after customers cancel them.

@zer0unplanned @Nonya_Bidniss @n_dimension OFC physically destroying the drives among dozens if not hundreds of identical ones with a physical shredder is also an option, but neither cheap nor fast.
- But in many cases that is the mandated way to do things to ease off lawyers and in any decent organization CISO & CLO will approve of it if they didn't mandate it already…

@kkarhan @n_dimension @Nonya_Bidniss No it is slow by design , I copied once the nuke OS of Kodachi OS which is Debian as the scripts are all viewable and copy pasta'able and made an usb with a universal script to nuke any machine once plugged in -

@zer0unplanned @Nonya_Bidniss @n_dimension yeah, I do want to do something similar with @OS1337 but a bit more precise, aiming fir #LUKS headers first so it'll take literally seconds to make it already non-recoverable.

@kkarhan @n_dimension @OS1337 @Nonya_Bidniss That is a harder nut, but if you realy want you can even beat up LUKS while I still ask why? that LUKS would be just a key to read overwritten data.
The aim is the data not the external defences. -

- This is a real security concern in #finance, where #ITsec literally has to deal with "Red Army Faction"-style hodtage taking scenarios as part of regulator-mandated #OpSec.
Just because a business doesn't have a shitton of cash at hand and banks neither doesn't mean that armed robbers would necessarily understand, much less accept.
- Similarly one may need to transit sensitive data but has to safeguard it against unauthorized access no matter the party accessing whilst providing plausible cooperation of it.

@zer0unplanned @Nonya_Bidniss @n_dimension Either way, comitting "#AssetDenial" is more often than not necessary and one may only have a few seconds before those exercising force may realize that a "duress code" was used and going for the #LUKS headers first may be the only feasible option in a short time...

@kkarhan @n_dimension @Nonya_Bidniss I'll try to do the same on an atomic image of fedora 43 as a pawn image in a box and will tell you if it worked with results. But need a 2nd fedora Atomic SilverBlue on that as a real challenge.
The years of me using Kali was very long ago just after backtrack, then I used Parrot OS rather but that all does not mater as it is all Debian RHEL
My os is immuatble with a rollback option> makes it very much trickier -

Problem with SSD "overwrite" is SSDs balance the writes.
So if your file is in A D J, SSD MAY balance the write to B E K to balance the cells.On the upside, SSD has one addressable cell, not a fuzzy magnetic dust.
