Global enterprises’ overconfidence and inadequate data sanitization are exposing organizations to the risk of data breach, at a time when proper data management should be at the forefront of everything they do, according to Blancco. Three quarters (73 … Continue reading Inadequate data sanitization puts enterprises at risk of breaches and compliance failures
Blinking an LED is generally considered the hardware equivalent of the classic “Hello World” project. It’s a quick and simple test to show that you’ve got the basics worked out, and a launching point for bigger and better things. So why should it be any different in this glorious new …read more
A NAS is always a handy addition to a home network, but they can be a little pricey. [Blake Burkhart] decided to create his own, prioritising budget and low power considerations, with a secondary objective to produce some router and IoT functionality on the side.
A Banana Pi R2 was a good choice to meet these requirements, being a router-based development board that also sports dual SATA connectors and gigabit Ethernet. [Blake] had some retrospective regrets about the performance of this particular SBC, but it does just fine when functioning purely as a NAS.
The enclosure for the device is …read more

Another group of researchers has demonstrated that hard disk drives (HDDs) can be interfered with through sound waves, but they’ve also shown that ultrasonic signals (i.e., sounds inaudible to the human ear) can be used to damage their integrity … Continue reading Attacking hard disk drives using ultrasonic sounds
Attack uses ultrasonic sound waves to disrupt HHD read/write operations, which could lead to a system crash. Continue reading Sonic Tone Attacks Damage Hard Disk Drives, Crashes OS
Spinners built into games of chance like roulette or tabletop board games stop on a random number after being given a good spin. There is no trick, but they eventually rest because of friction, no matter how hard your siblings wind up for a game-winning turn. What if the spinning continued forever and there was no programming because there was no controller? [Ludic Science] shows us his method of making a perpetual spinner with nothing fancier than a scrapped hard disk drive motor and a transformer. His video can also be seen below the break.
Fair warning: this involves mains …read more
There’s something to be said for the feel of controls. Whether it’s the satisfying snap of a high-quality switch or the buttery touch of the pots on an expensive amplifier, the tactile experience of the controls you interact with says a lot about a device.
[GreatScott!] knows this, and rather than put up with the bump and grind of a cheap rotary encoder, he decided to find an alternative. He ended up exploring hard drive motors as encoders, and while the results aren’t exactly high resolution, he may be onto something. Starting with a teardown of some old HDDs — …read more
In an entirely new twist on the security of hard disk drives (HDDs), a team of researchers from Princeton and Purdue University have released a paper demonstrating how acoustic signals at specific frequencies can compromise devices that rely on HDD tec… Continue reading Researchers use sound to compromise hard drives in new DOS proof-of-concept
We’re used to attaching peripherals to our computers, when we have a need for them to interact with the world around them. An Arduino Uno needs a shield to turn on the lights, for example. Just sometimes though there is the potential for unintended interaction between a computer and the real physical world which surrounds it, and it’s one of those moments that [Alfredo Ortega] has uncovered in his talk at the EKO Party conference in Buenos Aires. He demonstrates how a traditional spinning-rust computer hard disk interacts with vibration in its surroundings, and can either become a rudimentary microphone, …read more
Before hard drives became the main way for us to back up our stuff, they were a key evolution for the business world. They were also huge and costly. Continue reading Hard Drives Started Out as Massive Machines That Were Rented by the Month
