What is the local disk "D:" and why is it needed?

The main task that the local disk "D:" performs is the storage of the most important user information. The first section "C:" on the drive is bootable. It installs the operating system and programs. And the second, "D:", contains user files (documents, music, movies, photos, etc.). Such an organization allows, if necessary, painlessly to reinstall the OS. The first logical volume is formatted, and a new "Windows" with the programs is installed on it, and the second one is not affected. User data is saved, and after the installation of the software, you can immediately continue to work.

What it is?

First, we'll figure out how the local disk "D:" can be implemented locally. This can be done in two ways. In the first case, one physical drive is divided into 2 parts, which are called logical volumes. The second way is that two identical data storage devices are installed in the system . Each of the drives gets its name - the letter of the Latin alphabet. The first two of them "A:" and "B:" are reserved for disk drives, which are now practically not used. But the "C:" and the following letters are used to denote HDD, CD-ROM drives and various flash drives. The last character that can be assigned is "Z:". Therefore, there can be only 24 such devices on a computer.

Why is it needed?

Previously, several sections were created to sort the information. It could be as one drive, divided into parts, and several. Each of them was used for one, strictly defined task. But now such a practice is gradually receding into the past. There's no point in creating multiple partitions or installing more than two drives into the system in the home computer. The first one is "C:" - the system one. It installs the operating system and programs that are associated with it. But to store the user's files, the local disk "D:" is used. In its root directory, the corresponding folders (music, movies, for example) are created and this allows you to sort the information properly. As noted earlier, such an organization allows you to reinstall it in case of problems with the OS. In this case, important information for the user is preserved.

Possible problems

This arrangement of the disk subsystem has a number of drawbacks. The first of them is that when the PC is infected with a virus, problems with access to information are possible. In this case, a situation arises when the local disk "D:" does not open. In this case, it is recommended to boot from a CD or a flash drive and check it with an antivirus (for example, a free boot utility from the Kaspersky Lab). For greater confidence, you can use the file manager (FAR, for example). All the hidden files and folders in the root directory are deleted. But a simple OS reinstallation in this case, as practice shows, does not solve the problem. The second possible failure is when the local disk "D:" disappeared. This may be due to its hardware failure. In this case, you can not do without special software (the same "Acronis", for example). A typical user with a similar task is difficult to cope with, and without a service center in this situation, well, simply can not do.

Conclusion

The local disk "D:" is an important component of all modern home PCs. It allows you to organize the information storage structure correctly. Its main purpose is the storage of user information. But the programs and the operating system must be located in the system partition. It must be remembered and stored correctly.
