Explain the basic principles of disk partitioning

Before installing the operating system and software, you first need to partition and format the hard disk before you can use the hard disk to save various information. For the computer old "bird", this hard disk partition format is the most familiar, we mostly recognize and step into the computer threshold through this partition format. But many small rookies are just a strange term for partitioning. Today, I will introduce you to the problems of disk partitioning.

The disks in the computers we use are generally well-distributed, or sometimes reloaded. When the system is given by the technicians, there are many friends who use the computer to encounter such problems. Because there are too many things installed, the disk seems to be messy. I hope I can re-divide it, but I am afraid The data is lost or damaged, so the disk partition should pay attention to some problems, so that the data and other information will be damaged due to the partition.

In fact, partition is the most basic function of computer management. No matter the Fdisk command used in Windows 98 system to partition DOS, or the partition in the installation process of Windows XP system today, it gives users a lot of Convenience, of course, partitioning is not done blindly, we must consider the configuration of resources. In addition, PartitionMagic software can be used to prevent resources from being damaged during partitioning and to partition the space in the hard disk.

The following small series will introduce you to the basic principles of disk partitioning.

First, the partition format supported by common operating systems

FAT 16 FAT 32 NTFS

DOS Support

Windows XP Support Support

Second, the principle of reasonable partitioning

In general, the operating system is installed in the hard disk C area, and the disk as the system installer can not be divided too much (maximum of 5 GB), It should not be too small (minimum of less than 3 GB). It can be seen that there are still some principles in the partition. According to the author's experience in using computers for many years, the following principles are summarized:

(1) Partitioning utility

The capacity of the hard disk used by each person is not the same, and should be combined in the partition. The need, in the end how many partitions should be divided, how much capacity each partition should be divided.

(2) Partition rationality

The so-called zoning rationality is to facilitate the usual disk management, the number of partitions should be reasonable, not too much, too thin, because the number of partitions is still Will affect the system's startup speed.

(3) Data security

Data security includes data confidentiality, data backup and recovery. A good operating system can perform well under good user use because the user has one of the most basic requirements for partitioning the disk: data security. The partition of the entire disk is reasonable, and the disk partitions such as the system area, the data area, and the data backup area are clearly divided. Each partition has different sizes and functions. When the data is damaged or lost, it can be processed quickly and effectively. .

A partition is essentially a format for a hard disk. When we create a partition, we have set the physical parameters of the hard disk, and specify the storage location of the hard disk master boot record (Master Boot Record, generally referred to as MBR) and boot record backup. The information required for the file system and other operating systems to manage the hard disk is achieved by the advanced formatting, the Format command. The above introduction is for everyone to prepare the disk partition, I hope to attract the attention of friends, to protect their own information in the partition, so as not to cause unnecessary trouble.
