The 'Three Ton' Hard Drive Destroyer 206

Barence writes "Last year, PC Pro welcomed a DIY-style hard-disk destroyer into its Labs to wreak havoc on some unsuspecting platters. Now the technology has moved on, with the Ideal 0101 — a device that pierces disks with between 2.5 and 3 tons of force. 'It's not the quick cut-and-shut process you'd assume it is,' says PC Pro's reviewer. 'Instead, the 0101 seems to enjoy its particular method of torture.The punch emerges from the side of the bay, slowing piercing its way through metal, silicon and glass, before retreating once the disk is destroyed.'"

          There is a certain cutoff year where most of the pre-whatever drives are aluminum platter and the post-whatever drives are glass platter. Everyone whom does what we do, eventually has the "shattering" experience of discovering their first glass platter hard drive. And being precision ground surfaces they can't be prestressed like car windows, they leave some very nasty sharp jagged chunks of glass. Keep the 1st aid kit handy...

          The large old aluminum ones (think 5.25 or bigger) also rang with a clang you cannot believe if dropped on a tile floor. Deafening, almost. Don't try with the glass platters.

            This does not seem to be true across all manufacturers. I dismantle all of our drives before disposal, and I've only come across glass platters in laptop drives (they seem to have been glass all the way back to the early 1990s, the earliest one I disassembled was from 1992 and had glass platters). All of the 3.5" drives have had aluminum platters, from the cheap 5400 RPM drives to 10000 RPM drives from servers.

            It's possible that some manufacturers use glass platters in certain model lines of drives,

              Now that you mention it, the one that chopped my hand up (didn't quite need stitches) was a laptop drive from the early 00s. Also found glass platters in double-digit-gig high RPM (for their era, anyway) SCA SCSIs.

              For obvious reasons I don't try to pry stuck platters out anymore, so I don't know the ratios on modern drives.

            • by skids (119237)

              I've only found glass in the sub-3.5" class drives, more often than not. I've never shattered a platter, because unlike everyone else I know, I prefer to unscrew all the screws first and take them apart that way, rather than the prying with a screwdriver approach. It's more satisfying, like a puzzle, to figure out exactly what order to take things out for a given model.

              Glass is merely an alternative platter base material to aluminum. There are advantages to it (very good heat stability, for example) so it depends on the model. They've been around since the 90s.

              IBM DeskStars were probably the most common consumer drives with them, but the other manufacturers all had their own as well. These days it's probably even more a mess trying to figure out if a drive has glass or aluminum platters. I'm willing to bet even submodels of a particular model line vary - one submodel will

      Even cheaper, but not as fast, is the ATA SECURE ERASE command. Wipes your data even better than DD (because it erases 'bad' sectors from the G-list too), and is built into pretty much every HDD manufactured in the last 6-10 years.

      The myth about '32 erase cycles' and similar nonsense about reading data with an AFM is pure bollocks, and has been since the introduction of MR (and later GMR, CMR and TMR) head drives nearly 20 years ago (15 for non-IBM drives).

          Erased and encrypted (with a lost key) are not the same thing. A dedicated attacker could likely have a fun time with the latter, as there's potential for a fair bit of known-plaintext. ... of course, most of us are likely to encounter such an attacker. At work, maybe, but then we'd be doing wipe+destroy processes. At home, meh. I can't even give away old monitors, so Idoubt anyone'd end up with one of my drives.

            If done right, encrypted with a lost key can pretty much mean the data is not accessible:

            1: A diffuser needs to be used. This prevents an attacker from seeing the contents of sector 8 are the same as sector 5. TrueCrypt uses XTS mode. BitLocker uses AES-CBC and Elephant. Without this, it is easy to find patterns in the encrypted data.

            2: A keyfile must be used. Passphrases can be brute-forced. A keyfile ensures that an attacker has to guess out of the whole keyspace.

        Data is considered recoverable for under 3 passes of random data. From what I read, the binary data on your harddrive is stored as an analog wave, so it is very possible to recover most, if not all, of the data if you just do a single pass of zeros.

      No they almost certainly mean force. Shop presses are sold by force. 1000 psi hydraulic tubing, fittings, pump, and o-rings vs some diameter (area is what actually matters) ram equals X tons. The shop press manufacturer has no idea what shape die you'll install. If its a wedge, I guess the area is theoretically zero at the point and the pressure is infinite. More likely limited by the compression strength of the metal in the die.

      Chinese presses used to be famous for shipping with cast iron plates instead of steel plates. People die or are horribly wounded when the cast iron inevitably shatters. So be careful and/or buy or make your own steel plates. Another thing to look out for is Chinese "1000 psi" fittings and hoses might not actually survive 1000 psi when brand new, much less after years of abuse. So buying a press 10 times bigger than you think you need is not all that bad of an idea, assuming you can afford it.

  • I didn't read the article, only saw the video, but the video shows the machine punching only one hole through the disk? That leaves all the other data intact. Or does the machine keep repeating this step for the whole area of the disk and did the video show only one of the punches?
