How to quickly format and defragment a disk

Quick Format

The so-called fast format, in the format of the rewrite boot record, do not detect the disk bad cluster, the FAT table in addition to the bad cluster all the table items clear zero, the root table empty, the data area unchanged. Normal formatting overrides the boot record, checks the marked bad clusters, clears the rest of the table, clears the root table, and zeros out the data area. A fast formatted hard drive can be recovered by technical means.

The Format command under DOS is used for formatting.

FORMAT A: or C:, D: Wait, you can add some parameters later

For example, format A:/S This is formatted and appends the system. Which is to make a simple startup disk.

If you want to format your hard disk (before you reload the system)

You can use the format C:/s/q

Where,/S is the append system,/q is a quick format.

There are a lot of arguments behind the details.

FORMAT/? This command allows all command parameters to be displayed.

If you are good at English, you can grope for yourself.

Fdisk is used for hard disk partitioning.

The specific use of the method can also be used fdisk/? This command to carefully study

Defragment

Disk defragmentation, is through the system software or professional Disk Defragmenter software for the long-term use of computer disk debris and messy files in the process of reorganization, releasing more disk space, can improve the overall performance and speed of the computer.

What is disk fragmentation?

Disk fragmentation should be referred to as file fragmentation because the files are dispersed to different parts of the entire disk, rather than being continuously stored in a contiguous cluster of disks. After a hard disk is in use for a period of time, because of repeatedly writing and deleting files, the free sectors on the disk are dispersed across the disk in a discontinuous physical location, making the file unable to exist in contiguous sectors. In this way, when you read and write files, you need to go to different places to read, increase the head movement back and forth, reducing the speed of disk access.

Generation of disk fragmentation

When the application requires insufficient physical memory, the normal operating system produces a temporary swap file on the hard disk, which is virtualized into memory using the hard disk space that the file occupies. The Virtual memory management program frequently reads and writes to the hard disk, resulting in a large amount of fragmentation, which is the main cause of hard disk fragmentation. Other settings such as temporary files or temporary file directories that are generated when browsing information in IE browsers can also cause large amounts of fragmentation in the system. File fragmentation generally does not cause problems in the system, but too much file fragmentation causes the system to look back and forth while reading files, causing the hard drive performance to fall, and to shorten hard disk life.

The meaning of disk finishing

Hard drives are like houses that need to be sorted more often, and the Disk Defragmenter is used to defragment disks, and Disk Defragmenter can defragment volumes formatted with the File allocation table (FAT) file system, FAT32 file system, and NTFS file system. Disk defragmentation is the fact that the files on your hard disk are written back on your hard disk to keep the files continuous.

Only a continuous long time to read and write hard disk will cause a certain damage, but the defragmentation does not calculate damage to the hard disk, because most people will not be collated every day, and the time is very short, and not long time to read and write hard disk. You don't have to be too concerned about defragmenting your hard disk to make it work. It is recommended that you do a maximum of two disk defragmentation per month to keep your hard disk read and write speed in optimal condition.

Disk defragmentation interval Time

Average home users 1 months to organize once, business users and servers for half a month to organize. However, according to the percentage of debris to consider, such as in the windows7, debris more than 10%, you need to organize, or not.

Can disk formatting override disk defragmentation?

A: No, first clear the debris is to arrange the document properly, processing temporary documents. Make the hard disk work efficiency improve, speed up the operation. The quick format just deletes the file but does not really delete it, just does not show waiting for the new file to cover, so it can't speed up, and the slow format is OK
