Continuing the topic of SSD drives, it is important to mention that despite the absence of mechanical parts (surfaces where information is magnetically stored), the problem with bad sectors still persists. Now, however, the storage chips themselves often run out of resources, leading to the semiconductor drive freezing. This happened with an SSD built into an Apple computer. The computer would start, but the operating system failed to load.
After a thorough diagnostics, it was found that the drive had numerous bad sectors. While attempting to read data, the drive would freeze, and further work could only continue after power cycling. Nevertheless, the drive was read successfully, and 99.4% of the data was recovered.
