copies of FAT
The prerequisites for the fact that the “golden” discs are worse than the “aluminum” ones are laid down in the recording technology itself. Standards for compact discs provide that the reflection of the laser beam from bright areas should be at least 70%.
Such requirements are met for stamped discs. However, recordable discs, unlike stamped discs, have an additional recording layer of organic polymer. This layer has limited transparency. Therefore, standards for recordable discs allow that reflection from highlights should be at least 65%. Continue reading
Fall to the surface with a characteristic “crackle”. At the same time, they tear off microscopic particles from the surface, consisting of particles of the working layer of the carrier.
It is believed that drives can withstand thousands of “takeoffs” and “landings” of heads. Therefore, the rule – do not turn off the computer during the working day – is relevant. The fewer on-offs, the more likely the computer will not fail, the higher. Continue reading
Since when a file is deleted, it is not physically destroyed from the disk, it can be restored. As well as recovering all files in the case of, for example, accidentally formatting a disk. If the FAT file allocation table is intact, then you can easily find the first cluster that belongs to the file. However, the remaining clusters may lie anywhere on the disk. To restore a file, it is necessary not only to find all the clusters belonging to the file, but also to correctly determine the order of their sequence. Continue reading
