What partition format does a hard drive have What format is good for partitioning a computer hard dr

Needless to say, the second floor is very clear.

It is good to use GPT format for computer hard disk partitions. The full name of GPT partition is Globally Unique Identifier Partition Table Format.

One of the great advantages of GPT partitioning is that it creates different partitions for different data and creates different permissions for different partitions. As the name suggests, GPT ensures the uniqueness of the GUID of a disk partition, so GPT does not allow the entire hard disk to be copied, thus ensuring the security of the data on the disk.

My opinion is:

As a backup partition, it is better to use FAT32 format, which has the best compatibility. Of course, since it is a backup emergency (or as a recovery system!) ).Usually try to use this partition as little as possible.

For other partitions, NTFS can be used to get better performance and efficiency.

There are 3 types of hard disk partitions, namely primary partitions, non-DOS partitions, and extended partitions.

1. Primary partition.

The primary partition is a relatively simple partition, usually located in the front area of the hard disk, forming a logical C disk. The main bootloader is part of it, and this section of the program is mainly used to check the correctness of the hard disk partition, and determine the active partition, which is responsible for handing over the boot power to the DOS or other operating system of the active partition. If this program is corrupted, it will not boot from the hard disk, but it will be able to read and write to the hard disk after booting from a floppy drive or optical drive.

2. Non-DOS partitions.

In the hard disk, the non-DOS partition is a special form of partitioning, which is to divide a piece of the hard disk separately for another operating system, and for the operating system of the main partition, it is a piece of storage space that is divided. Only non-DOS partitioned operating systems can manage and use this storage area.

3. Extend the partition.

The concept of extended partition is relatively complex, and it is easy to confuse hard disk partition with logical disk. The fourth byte of the partition table is the partition type value, and the normal bootable basic DOS partition value greater than 32MB is 06, and the extended DOS partition value is 05. If you change the basic DOS partition type to 05, the system cannot be started and the data in it cannot be read or written.

If you change 06 to a type that is not recognized by DOS, such as EFH, DOS thinks that the partition is not a DOS partition and cannot be read or written. Many people use this type of value to implement the encryption technology of a single partition, and restore the original correct type value to restore the partition to normal.

You can use the default system.

The smaller the distribution unit, the more space saving, and the larger the distribution unit, the saving time of reading, but the waste of space. This may seem like a smaller distribution unit would save space, but it is not. The more chunks a file is divided into, especially when these storage cells are scattered, some time is wasted just reading the data, and you can imagine that the head is wasting time when the platter is struggling to move around the data bit by bit.

It is better not to install the application on a partition with a cluster that is not 4k, as it will reduce efficiency.

Therefore, it is recommended to maintain the system's default allocation unit size.
