The binary system was first described in China in the book 'I Ching' more than 3,000 years ago. In the 17th century, the famous mathematician and philosopher Gottfried Wilhelm von Leibniz refined the concept of binary arithmetic. The hexadecimal (HEX) system developed later as a tool for more efficient work with binary data. The decimal system (DEC), which we use every day, is as old as humanity itself and is the foundation of our understanding of numbers.

Most data recovery cases then become a task for an experienced specialist. Even a seasoned expert could be stumped in many cases without the availability of advanced technologies. This article discusses a modern 4TB hard drive from WD, where the absence of certain technologies could have severely complicated, if not made impossible, the data recovery process.

Extracts the Key and Unlocks the Data](https://www.exalab.cz/images/blog/EA2309221-1-Hard-Key-cesta-k-srdci-mobilu-w1200.jpg) ## [ Hard Key - The Path to the Heart of the Mobile. Extracts the Key and Unlocks the Data ](https://www.exalab.cz/en/blog/from-practice/hard-key-the-path-to-the-heart-of-the-mobile-extracts-the-key-and-unlocks-the-data) A damaged mobile phone and a desperate user is a scene we encounter frequently. Regardless of the reason for the mobile phone's failure, data recovery can be a complex task not only for the technician but also for his assistant, capable of peering into the silicon heart of the mobile. Data recovery demands expertise, technological know-how, finesse in handling the hardware, and in many cases, also PC-3000 Mobile - hardware and software from Acelab's laboratories.

Whether it's a user's attempt to "repair the disk" or a careless intervention by an IT service lacking the necessary expertise, the result is often the same - extensive disk damage and an increased risk of data loss. In today's digital world, that's definitely not good news. That's why it's crucial in these cases to consult professionals - data recovery experts equipped with the necessary tools, knowledge, and experience.

Quick phone diagnosis can be crucial ](https://www.exalab.cz/en/blog/explanations-and-tips/data-from-a-broken-mobile-can-usually-be-recovered-quick-phone-diagnosis-can-be-crucial) The mobile phone is currently one of the most important devices we own. It's something like a personal assistant, diary, camera, and communicator, all in one. Without it, we would often feel lost - it is our connection to family, friends, work, and the world. Unfortunately, this dependency on our phone can be a double-edged sword. What if it suddenly breaks or is water damaged? What are the data recovery options?

How valuable is your data? ](https://www.exalab.cz/en/blog/from-practice/repairing-hard-drives-according-to-guaranteed-guides-from-the-internet-how-valuable-is-your-data) A hard drive can, after a fall, a collision, or even spontaneous failure, get into a state that can give a curious user with a sharp ear the impression that they can access the inaccessible data themselves. After a while of researching on the internet, loosening those strange screws, and a bit of prying with a screwdriver, "stuck read heads" appear. If the user hasn't destroyed the disk by this point, they're certainly well on their way, if they progress to the next level of the data experiment.

The history of NAND began in 1987 when Toshiba introduced the first NAND flash chip. Widespread expansion of NAND chips was achieved around 2000. Between 2010 and 2015, thanks to reduced production costs and improved reliability, NAND memories began to massively expand. SSDs almost completely replaced system disks in new computers, while the capacities of mobile phones, memory cards, and flash drives increased and prices fell to an acceptable level.

The drive was used in an industrial machine since its production year. After years of reliable performance, the drive started to malfunction, causing issues with the operating system and the machine's tasks. Our mission was to create a binary copy of the disk and attempt to recover the data, enabling the operating system to be restarted.
