Verbatim hard drives have been on the market for many years and are popular among users, likely due to general brand awareness and the balance between capacity and price. However, Verbatim does not manufacture these hard drives themselves. Inside the plastic case, one may find a hard drive from Seagate, Western Digital, Toshiba, Hitachi, or Samsung. Therefore, data recovery can vary depending on the brand of the internal drive and its symptoms.

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.

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.

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.
