Formatting and quick Formatting differences

Hard disk generally need format to use, this is mainly due to the various operating systems must be in a certain way to manage the disk, and only format to make the structure of the disk can be recognized by the operating system, the format of the disk is divided into physical format and logical format. Physical formatting, also known as low-level formatting, is to process the physical surface of the disk, establish a standard disk record format on disk, divide track and sector (sector). Logical formatting, also known as advanced formatting, is the creation of a system storage area on disk.

Hard disk format is currently used most of the NTFS format and FAT32 format, the general format is divided into ordinary format and fast format, fast format words faster, then what is the difference between the two?

　　Formatting and quick Formatting differences

Fast format is not the real meaning of the format, the new chimney is just quick to remove everything in the partition, if there is no virus problem so it is possible to save time. But if there is a virus problem, some stubborn virus such fast format is clear, to formal format, so that the hard drive a little bit of thorough clean can be cleared.

A quick format is a "formatted" tag for this disk. Although all the information in this disk can theoretically be recovered by special software such as Easyrecorver, it can only be recovered by these special software. The disk Trojan has been cleared (100%) unless you intentionally restore it with special software. Ordinary formatting is not possible with special software to restore the previous data, only this is the difference. However, if you have a Trojan horse or virus in your system disk, and they are running, even if you format the other disk, the virus may re-write itself in the formatted disk. Fast formatting is the erasure of data on the partition, which takes from a few seconds to a few 10 seconds.

Slow formatting is the erasure of the data on the partition, and then fills in any data to fill the partition, then erases the data to achieve destructive erasure of the original data. And in the erase after the format operation, side to the hard drive for bad inspection, while partitioning. Time-consuming varies from hours to more than 10 hours. Ordinary computer system optimization and maintenance only need to use a quick format, if your hard disk data is more confidential, it is to use slow format.

Here are a few quick formatting differences from normal formatting:

First, the rapid format is just to delete the files on the drive, Beijing waste recycling and not the disk sector rewrite. The normal format overrides the disk sector, so it's a bit slower.

Second, the rapid format is just to erase the surface of the data, or can be recovered by means. The normal format, in addition to erasing the data, will also detect the hard disk, so the time is longer.

Three, the normal format time is very long. But will be in the format of the full detection of the hard disk, if there are bad DAO will prompt. Fast formatting takes very little time, but if the hard drive has a bad path, there will be no hint, so if you have plenty of time, it is recommended to do it in full format.

Four, fast format is simply to remove the storage media (hard disk, floppy disk, USB stick, etc.) files in the delete. Generally formatted (fully formatted) in addition to deleting the file system, the sector of the storage media is also detected, so the speed is much slower than the fast format.

Five, in general, not to confirm that the storage medium has a problem and just delete files, with a quick format can be, but to analyze the bad sectors, you must use the general format.

Six, in general, you can choose to quickly format, faster. If you suspect that the hard drive has a bad path, you can try normal formatting. Low-level format lower levels format too many will damage the hard disk, generally do not need, and is not recommended to use.

Seven, both of these are high-level format that is, the difference between the two is that the fast format is simply to clear fat table (file allocation table), so that the system does not have a file on the disk, do not really format all the hard disk, quickly formatted after the tool to recover hard disk data, This is the reason why fast formatting is much faster. Do not choose Quick Format, the ordinary formatter will scan all the tracks on the hard disk, erase all the contents on the hard disk, not recoverable, normal format can detect the hard drive on the bad path, slower.
