@cybersecknight: This Is How the Government Destroys Data

Queen Elizabeth II :

this does nothing with modern ssds that have wear levelling

jonkler :

so are you telling me my 13tb of family photos can be recovered?

Suppe :

why genuene question but what's the difference between overwriting everything with 0s once and 7 times

78lyta :

Don't overwrite SSDs! Use ATA Secure Erase or equivalent for NVMe, much much much faster and more secure.

intheknow42 :

probably just writing binary 111111111 will be the best, used to be a hard drive engineer and head the opportunity to look at data at disk data with an oscilloscope, for things like what happens that caused a disk to fail, from power cuts during operation, to a drop or push whilst the disk is still writing, such things can cause data to be written at offsets, to do root cause analysis, one would just write 1 single sector of the dish and look at the sectors before and after then send the disk heads to either offset and see when the magnetic decreases or increases, compared to the sector just written, writing a 1 to dish sector provides the magnetic reset the sector needs to overwrite the magnetic track on the disk. offset to the magnetic track I doubt there will any data which can used to see what was written in that disk, it just doesn't happen. with the right oscilloscope and the known information to rig the many pins needed, would just show offset reading as nothing magnetic, where the actual tracks will show the magnetic zeros and ones.

A :

is it common for memory sticks to brick after doing a 0 fill? I've had a couple that just corrupts the data afterwards

Light :

I got a 1tb hdd since 2011, windows locked me out at some point and i formated it 1 or 2 times after can i retrieve photos i had from the windows 7 i had in 2011 ?

boni :

Does Blechbit work?

Codda :

what about laptop driver, the smaller hdds, does the same logic apply to them also?

etbenson808 :

thought the method in the 90's was bit flipping sectors 5 times, because of the slightly higher quality of drives above consumer grade

Tom :

so apparently the zeros dont work for SSDs? something about the controller in them not actually writing the bits or that theres some history still stored in them?

Emma Audrey :

and when you want to restore data cause you moved a little bit your PC form left to right, is always impossible, always the worst case scenario to restore or/and your data is lost forever....

espismaznegerus :

test

Lucas Tak :

Don’t they just destroy the drives?

iß_illes :

for spinning drives scratch the disc

Cloaker :

BezdeeLiiga :

Since 2000 there is built in wipe function in HDD, if interrupted locks drive and it cannot be used anymore, by regular folks. Just run one small command and HDD performs wipping autonomosly, it does not need OS for that, just electricity.😎

Midnight_Torque :

coulnd u just go into winPE and delete the sector?

Jari Kooper :

Our datacenter standard was send a huge magnetic pulse through the drive and then bent it 90° in a hydraulic press

jeffy sumthin :

mi may just be old but, DBAN

Bustin_Cider :

Depending on the security sensitivity It literally goes in a machine and hardware is destroyed.
