AskWoody_MVPSurely the whole point of putting unwanted hard drives through an industrial shredder is to recover the materials contained within the drive, some of which quite expensive (like gold and neodymium). The common stuff like copper, steel and various plastics also have a value, if fairly small.
The Waste Electrical and Electronic Equipment (WEEE) recycling firm we use gets paid an amount for each skip*-full delivered to the industrial shredder firm!

AskWoody MVPBut for cases requiring a higher level of security, multiple overwrites with random ones and zeros make the old data much harder to recover, even with lab-quality forensic tools
On modern hard disks – anything in the last 20 years – a single pass over all sectors with random data makes recovery impossible, forensic tools or no. The disk structures don’t retain previous data – if they did your newly written data would be liable to random corruption from the old data.
The only time data is potentially recoverable is if the data areas of the disk are not overwritten, which happens when you perform a quick format or remove and recreate partitions.
If the disk is still working and you want to sanitize it, boot from a DBAN disk and run a single pass with random data. (Don’t bother with the commercial product that pops up when you search for DBAN.)
If DBAN won’t boot (secure boot) or doesn’t recognise your disk drive, try:
Hiren’s BootCD. (Use Lazesoft Disk Image and Clone, Wipe Tools, Erases with one-pass random characters)
EaseUs Partition Master.cheers, Paul

AskWoody_MVPIn support for what Paul said:
https://www.techrepublic.com/article/disk-wiping-and-data-forensics-separating-myth-from-science/
Key points: For modern HDD’s a single pass is enough. Caveat, outdated regulations for certain industries still hold to the myths. Follow their procedures as required and get a certification for each drive shredded. (sigh)
Modern SSD’s on systems that implement TRIM are quite likely already secure. I know in my business retrieving deleted files on SSD’s is really hit or miss depending on when the last TRIM pass was conducted.

AskWoody MVPSurely the whole point of putting unwanted hard drives through an industrial shredder is to recover the materials contained within the drive
Silly me… I thought the whole point was to annoy your colleagues, ‘cos only me and the Data Protection supervisor had ear defenders.
We replaced 8 PC’s in the office of a local council-owned theatre. As they had been connected to credit card terminals the HDDs had to be physically destroyed rather than data-wiped to DOD-level. (The CSO let me know *after* I had DBAN’d them all… something to do with credit card regulations.)
I was given the job of shredding them, accompanied by a DP supervisor who countersigned the destruction. As the first HDD disappeared up the conveyor into the maws of the shredder a couple of bosses rushed into the maintenance room to beg us to shred the next 7 HDDs out of hours due to the appalling racket. However, we couldn’t do that because there were no Health & Safety/First Aid staff available out of hours.
After all 8 HDDs were shredded, all subsequent shredding was outsourced and the very expensive inhouse shredder was never used again. I was glad… my ears rang even using ear defenders. 🙂

AskWoody PlusI really have to wonder what is so important on a drive used in a personal computer that simply drilling through the platter(s) would not be sufficient. No one is going to spend thousands of dollars and multiple hours trying to recover data from a platter with hole to recover a Facebook password. Difficult to recover data from a platter that will not spin due to the imbalance. Doing the same destruction a SSD is the same logic. Although SSDs are easy to crumble.
Critical places, such as healthcare have regulations requiring more thorough destruction. Even then I wonder why anyone would expend any effort to gain access to an MRI of someone they do not even know.
Government agencies, as in any 3 letter combination would require complete destruction, as in tiny pieces. Many contractors working on government contracts would also have complete destruction requirements.
For the home user, a simple hole, then out with the garbage is sufficient.

Responsible people dispose of electrical items like this via the local authority disposal/recycling schemes, no matter how one makes the device inoperable/unreadable.

AskWoody LoungerI typically use a drill right through the platter which makes recovery of any data impossible. Of course there are plenty of disk utilities that can do a very good job of erasing data. I know of one person who simply encrypts the data on the disk and disposes of it. I know of some who remove the platters and physically shred them.

GuestMaybe I just enjoy taking things apart, but the last time I had drives to destroy, I disassembled them recovered the very fine strong magnets, and then took a propane torch to the platters. When they’re almost molten, it’s safe to say the data is gone! plus, they turned all kinds of pretty colors, and I had fun doing it!

AskWoody LoungerThe likeliness is nothing you have is so important you need to worry about doing more than just wiping it properly and overwriting it once. AND if your data is important enough to be searched for, you already know every imaginable method under the sun of how to destroy it completely, and don’t need advice in doing it. If you are the latter, you are like me, reading this to read the funny stuff people do. WHAT I have been doing, since everything I do is complete secrets that the Illuminati are trying to get their hands on, is I take a rocket to the outer edges of the universe, and I toss my old hard drives into a black hole. I have found 100% success with this method.

GuestDestroying old hard drives.
I had several old hard drives which I finally got around to destroying but I did it slightly different.
I always like to get the most from things.
- Dismantle the old hard drive and remove the rare earth magnets. They are excellent for use in many projects.
- Remove the platters and use them for drink coasters. They are easy to clean, look great (conversation piece) and last a long time.
- Less goes into the garbage.

AskWoody PlusAbout destroying old hard drives, I take them apart. They have strong magnets in them and I can always use more magnets. Then I either scratch or cut the individual disks to make data recovery harder. Usually I have already done some kind of data erase first. Taking apart a hard drive is fun and interesting for me.

AskWoody MVPBeen there..unscrewed pentalobe casing screws in IDE drives, nice shiny platters used as cup coasters for my desk once dissasembled. Even kept the controller PCB’s should replacements be required for like-for-like drives in an emergency. As it turned out no, the PCB’s were thrown out much later on a clearout, still have the magnets!
These platters were in a vacuum but the controller PCB’s were usually outwith this area of the HDD that made them useful as replacements. Connor (early days)/ Quantum/ Maxtor/ seagate/ Western DigitalNo problem can be solved from the same level of consciousness that created IT- AE

AskWoody PlusMany years ago I was an IT Manager for a charity here in the UK. Inevitably we had to be more careful than most with the pennies. One of my staff was ex army & as we were located in a semi rural location he was into huntin’, shootin’ & fishin’. If we had drives to dispose of he would bring a couple of rifles in & use them for target practice a very effective disk hole punch!

Nibbled To Death By Ducks
AskWoody PlusUmmm…missed this one.
But belatedly: A friend of mine who lives in the country uses a 10-guage shotgun, puts down a tarp, yells “Pull!”, fires with dead aim, which then reduces it to very small parts, then rolls up the tarp and bags the smithereens, which go into the town’s annual Electronics Recycling Event.
Must be satisfying… 🙂

AskWoody PlusRecently I got a tear sheet for a commercial hard drive crusher.
- NSA evaluated and listed with durability rating of 204 drives per hour
- 8-second crushing cycle
- 115V/60Hz standard power (international voltage available)
- Compact, portable, and quiet
- Destroys enterprise drives with rails still attached
- Made in the USA
See https://www.semshred.com/0101-free-anvil/
For somebody with a lot of drives seems like a solid machine. Not sure how they integrate a hydraulic press with a drill but that what it look like.
