Ransomware is one of the most serious threats to data for businesses and individuals alike. But between the initial shock of a locked screen and the actual state of data on the drive, there's often a huge difference. In this article, we'll show you from a data recovery lab's perspective when data can be saved, when it's too late – and most importantly, what to do in the first minutes and what to absolutely avoid.

##  [ Forgotten Data on a Forgotten Interface ](https://www.exalab.cz/en/blog/explanations-and-tips/forgotten-data-on-a-forgotten-interface)

Two old Maxtor hard drives landed on our desk after sitting in a drawer for years. No drop, no clicking, no visible damage. But their owner discovered he had nowhere to plug them in – the interface that once powered the majority of home and professional computers has completely vanished from today's machines.

##  [ File Recovery from LaCie Hard Drives: Ordinary Disks in Stylish Cases ](https://www.exalab.cz/en/blog/explanations-and-tips/file-recovery-from-lacie-hard-drives-ordinary-disks-in-stylish-cases)

LaCie external drives are often considered a higher quality brand by users. Some look more durable, while others may seem more luxurious. For example, some of our professional photographer customers considered them a better choice based on recommendations in forums. However, the truth is that inside the stylish case lies an ordinary hard drive, and thus they suffer from the same issues. Only the drive's case might add a bit of robustness. No miraculous formula has granted LaCie drives immortality.

##  [ BIN, HEX, DEC - The Building Blocks of the Computing World ](https://www.exalab.cz/en/blog/explanations-and-tips/bin-hex-dec-the-building-blocks-of-the-computing-world)

The binary system (BIN), which forms all software and hardware in computing, is not an invention of modern times. 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.

##  [ Non-Initializable Disk: Data Recovery is a Task for Specialists ](https://www.exalab.cz/en/blog/explanations-and-tips/non-initializable-disk-data-recovery-is-a-task-for-specialists)

An uninitialized disk in the hands of a "daring IT wizard" can spell disaster for data. 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.

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?

##  [ NAND - The Chips that Gave Modern Electronics Memory ](https://www.exalab.cz/en/blog/explanations-and-tips/nand-the-chips-that-gave-modern-electronics-memory)

NAND flash memories can be found in most of today's data storage devices, without which personal computers, mobile phones, flash drives, memory cards, and control units would hardly be able to operate. 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.
