Title: Wiping a hard disc before we dump our old PC
Post by: Buffin on August 18, 2020, 08:18:20 PM
Our old all-in-one PC (upgraded to W10) kept hanging, so we bit the bullet and replaced it with a Dell, which is whizzing along nicely  :thumbsup:

We don't just want to dump the old one at the tip, being conscious that there's possibly still stuff on the hard disc (though I've overwritten whatever I could find).

I can't see how to break open the case to get the HD out. Any advice, please, on what to do with the HD to make it secure?

Thanks, and apologies for the laymanspeak.

Similar to @class37025 (https://www.ngaugeforum.co.uk/SMFN/index.php?action=profile;u=311) , but with a twist...

...claw hammer.

Easier to wield, claw helps get into the case, and once in, give the hard drive a good work over with the claws.


Oh yes, in case you're wondering, no, I'm NOT joking.

Once I've got an old/dead HD out of the machine I take the HD drive apart.
Over the years I've acquired a handy collection of round mirrors for seeing awkwardly located things - and an eclectic collection of very odd-shaped fridge magnets  :D

Yes, smash the discs up with the largest lumphammer you can get hold of.   

I had to do eight of the things out of one system once.

I only bin a hard disc when it's broke, otherwise I remove from the old PC and either install as an additional disc in the new PC, or mount it in an external drive case. You can use it as additional storage or as a back up.

To open a PC undo screws on the back to remove the side plates

For my money, I tend to use a drill with a nice HSS bit, three or four holes through the case and the plattens and your done :)

If you don't want to physically destroy the HDD and can remove it, install it in your current machine as a secondary drive, open a command prompt and run:-

format d: /fs:NTFS /p:1 where "d" is the name windows has assigned to the secondary drive. This basically overwrites every sector of the HDD with zeros.

It's an urban myth that you need to overwrite a squillion times, once does it, as long as it's done properly.

If you're going to dump it, hammer. Don't believe the internet trolls that tell you that the FBI and Interpol will piece it all together and then arrest you for being part of the vast worldwide n-gauge conspiracy. They've already taken brain scans when you're using your phone, so they've got all they need on you anyway :)

Seriously, a hammer. I've done it myself a couple of times, and it's very cathartic if it was the drive that went bad on you.

Then you might like to take the computer and what's left of the hard drive to a recycling place that takes electronics and dead batteries rather than just dump it though, there's some toxic stuff in there that's not good for what's left of the planet.

Plus useful stuff that can be recovered to save digging up more.

Wot 'e said.

Reduce - reuse - recycle.

Sorry, omitted a step...

Reduce - reuse - beat the crap out of - recycle.

couple of pounds of nitro glycerine should sort it,much less effort than hammering. Or boot from a linux live disc and run the dd command,you could then install a lightweight linux distro and use it as a second machine

There isn't actually a lot you can do without access. I keep them in the basement for some years when they become inaccessible and then chuck them.

If you can access the drive use a hard disk tool of some kind (I don't know what WIndows offers for this) that issues the secure erase commands. That's the only documented safe way to erase a drive. Overwriting files may or may not work because the disks don't necessarily use the same bit of disk when you overwrite as it did for the original. The secure erase commands actually tell the drive to do a full erase and were added precisely to deal with disposal/recycling for re-use.

The reality though is that without some specialist knowledge and/or effort smashing the circuit board on it is probably enough. Someone is not going to go around all the disks at the tip fitting new circuit boards just in case - not unless you've upset a government or the illuminati 8)

Windows 10 has a utility called Diskpart. you can access it via the Search bar on the bottpm

use "list disk" to see the pC disks and "sele X" to select disk X

it has a command - "Clean" which deletes all disk partitions on X or "Clean All" which deletes all partitions and writes 0's in every sector on X

or several disk wiper utilities available on web to make a bootable wipe disk (Boot'n NUke is good)

Usually bank account details and logins, cloud account passwords, names and addresses, basically anything that can be used to steal your identity or money. Also things like confidential email and work files.

I once visited a company that recycled  computers  for the police and NHS they had a programme that wiped discs completely  and the computets  were sold on ,however  if the device had been involved in a crime it was striped in a secure room and the disc physical  shredded.  Phones and tablets went in whole and made a satisfying crunching sound

Once we're out of the current craziness you're welcome to bring said disc up to mine and we'll have a cuppa whilst smacking rifle rounds through it.

I agree with Mike. With an HDD docking station you can use the hard drive as an external drive, which is jolly useful for making backups (data and/or system) that are less likely to become corrupted, as once they're disconnected they can't be attacked by viri  :)

Garden incinerator!

But seriously I have to destroy any paperwork that have my customers details on (Data protection act) Don't trust shredders as people with time on their hands that are good with jigsaw puzzles can put pieces back together! so I burn it.

its not a big heap to cause annoyance to my neighbours (after 7 pm)  I had a couple of old hard with drives with business data on them that I chucked in there while the paper was burning.

Next morning when I emptied the incinerator blobs of alloy that were once molten from the hard drives and also chard shells.

Beats hammers!  ;)

The Bank of England, or maybe the Royal Mint, must surely have machines that can destroy coins withdrawn from circulation ?

Give them a ring

If you go the hammer route, remember to wear safety glasses as the silicon disc will shatter into pieces that are very sharp and travel a surprising distance.

Very true, though I find there's no need to open the drive case - just bash a 6" nail through it  :D

What a waste, destroying a hard disc; when you get the new PC get one with an SSD say 256Gb to use only for software, install the old hard disc and use it for storing data, images, music etc. The SSD gives you a faster machine but a large SSD costs more, so use the old disc for the data which is not so dependant on speed.
Both my PCs came with 256Gb SSDs and I installed 2Tb hard discs from older machines, my laptop has a 125Gb SSD and a 500Gb external drive, plus I have a couple more External drives one is image back up, the other video and music back up.

Not really a waste when it's an old low capacity disc that's been running for many years and is likely to fail in the near future anyway. They do have a finite lifetime.

Totally agree it's worth re-using reasonably new discs of reasonable capacity. I have a couple of old discs now sitting in external drive enclosures.  They don't get used much nowadays though, as I use a Network Attached Storage drive (NAS) for centralised storage of data and media (and as a printer server).  The NAS is easy to access from any of our household PCs and TVs, and easy to back-up.

If you can get past the 6 layers of physical security at their data centres, Google have some rather good machines that can destroy a hard drive in seconds.
