main task that performs local disk «D:», - the most important is the storage of user information.The first section, "C:" to drive - boot.It installed the operating system and programs.But the second, «D:», contains user files (documents, music, movies, photos, etc.).This organization allows, if necessary, reinstall the operating system painlessly.The first logical volume is formatted, and it established a new "Vindovs" programs, and the other is not affected.User data is stored, and after the installation of software, you can immediately continue working.
What is it?
To begin with we shall understand how the hardware can be implemented in local disk «D:».This can be done in two ways.In the first case, a physical disk is divided into two parts, which are called logical volumes.The second method consists in the fact that the system has two identical storage device.Each of the drives gets its name - the letters of the alphabet.The first two "k" and "B:" are reserved for floppy drives, which are now hardly used.But the "C:" and following letters are used to refer to hard drive, CD drive, and various flash drives.The last character, which may be assigned, - a «Z:».Therefore, a computer can be a total of 24 such devices.
Why is it needed?
used to sorting the information to create multiple partitions.This could be as a single drive, divided into parts, and more.Each of them was used for one well-defined tasks.But now this practice is gradually receding into the past.It makes no sense to create multiple partitions or set in more than two drives in a home computer.The first of these "C:" - system.It installed the operating system and programs that are associated with it.But for storing user files using the local disk «D:».At its root directory are appropriate folders (music, movies, for example) and it allows you to sort the information properly.As noted earlier, this allows the organization in case of problems with the OS reinstall.This important information for the user is stored.
Possible problems
This organization of the disk subsystem has a number of drawbacks.The first is that with the defeat of the PC virus may be problems of access to information.This creates a situation where not open local disk «D:».In this case, it is recommended to boot from a CD or flash drive and check Antivirus (for example, a free utility from the boot laboratory "Kaspersky").For greater certainty, you can use File Manager (FAR, for example).All hidden files and folders in the root directory is removed.But a simple reinstall the operating system, in this case, as practice shows, does not solve the problem.The second possible failure - is lost when the local disk «D:».This may be due to its hardware malfunction.In this case, no special software is indispensable (the same «Acronis», for example).Normal user with such a difficult task to manage, and no service center in this situation well, just can not do.
Conclusion
Local disk «D:» - an important component of all modern home PCs.It allows you to organize the structure of information storage.Its main purpose - is to store user information.But the program and the operating system must be located on the system partition.It must be remembered and properly maintain their data.
