Fast formatting. Full and fast formatting: differences in application. How to be with ssd

Berlin Ilya Nikolaevich:
Fast formatting destroys only data tables (tables) of files + MFT, not a touch area of \u200b\u200bdata. The usual formatting completely destroys the data on the disk, and, accordingly, lasts more than a longer. When installing XP, in principle, any type of formatting will fit, but when installed in the section, where Windows has already been installed, it is better to choose usual formatting - so more reliable and calmer.

Yuri Aleksandrovich Pancyovich:
Fast formatting is cleaning the file placement table, and the entire disk is formatted. If the disk was normal, i.e. Without software failure sectors, then complete formatting for nothing.

Shurovik:
Fast formatting and full formatting. In the first case, only the file table is reset (and the data physically remains in place and can be restored), in the second - there is a complete overwriting with zeros of the entire working surface of the disk.

Gennady Pal:
With full formatting, in addition, the surface is checked, and if there are unreadable clusters - their mark. Such formatting is required for disks of old and suspects in errors when writing and reading.

Divided into two types - fast and full. In this note, I will talk about how fast formatting is different from full and when these types of formatting should be applied.

So, what is the difference between rapid and complete formatting?

When quickly formatting is re-created only (the file system table is overwritten), while the data area is not affected.

With full formatting, first is performed for availability. If such sectors are detected, then the check program tries to fix them, and when the failure marks them as faulty (BED sectors). Accordingly, such sectors are excluded from the file system tables that are formed after a complete surface check. This means that in the future, the data is not recorded in the faulty sectors.

It can be said simplifying that in the process of quick formatting, the disc partition is noted as clean. After this formatting, you will not find on the formatted disk previously stored files there, and this creates the feeling that the files have been removed, although it is not. In fact, all files remained in place, but the operating system will read this section blank and will record new information on top previously recorded. This means that if you wish, the information with an erroneously formatted partition can be restored, but there are many factors affecting the success of recovery and I will tell about this one else time.

Unlike quick formatting, full formatting includes also pre-testing integrity hard diskThat is, there are damaged sectors. Since, with this operation, each disc sector is checked separately, then complete formatting takes an order of magnitude longer than fast. Full formatting time is primarily on the value of the formatted section.

When should I use fast, and when complete formatting?

It is difficult to give some clear recommendations, but I usually do this: if I need to delete all the data from the hard disk partition or from removable media, for example, flash drives, then I use fast formatting, as it is performed in seconds. If I have a suspicion that there appeared on the disk bied sectors, or what has occurred damage to the file system (as a result of the action of the virus or with incorrect removal of the media of the information from the compute), then I use complete formatting.

And in conclusion I want to say that the formatting process does not harm your hard disk or removable media information and you can format without fear of damaging them.

Many computer users confuse two concepts, it is formatting and defragmentation, these concepts differ fundamentally from each other. Defragmentation is the layout of fragments of files for more quick access to them when as formatting it full removal These files. In this article we will analyze how the usual formatting from fast and how to format through the medium operating system.

The difference between normal formatting from fast

Fast formatting is that the files themselves are deleted and cleared the disk markup table, about which I wrote in the article what is a file system and what to choose FAT32 or NTFS that is removed only by the location of certain data recorded on the information carrier and not Files themselves.

But how then happens new post? Many will ask, because, as we know, in order to place something somewhere, you first need to fully release this place. In this case, this principle does not work. Again I remember the article about the file system, I spoke in it that the sectors on the disk are marked as free or engaged in information.

So, if there were no these labels, then the integrity of the information would constantly have been broken, due to the fact that every time recording new information Those sectors on which the record had already had was simply overwritten by new information.

The whole point of quick formatting is that the files are physically not where they do not disappear, they simply become invisible to us. They are still stored on certain sectors and when recording for these sectors of new information, simply are simply replaced.

Advantages of quick formatting: Formatting speed, the ability to restore data using special programs.

Normal formatting, destroys not only the data in the disk markup table, but also removes them physically.

Advantages of normal formatting: It is recommended to produce only when there is damaged sectors on the section, or when installed on the new copy of Windows.

How to format the section, USB flash drive through the Windows operating system

ATTENTION! All data that was stored on a particular section, or flash drive, after the formatting procedure will be lost.

1. We go to Start > My computer

2. Calcation right-click Mouse, on the section icon, LIBERA Flash drive, which you need to format, dropping the list, select the item ( Format…).

3. Select in the list ( File system) the system in which you need to format file System can be read in the article

Formatting disk, flash drive or some other media in the latest versions of the Windows Operations, different methodsThe user can choose quick formatting or full. As a rule, novice users do not understand what the difference between these types of formatting, and which one can approach a specific case.

Below will be described the differences in the high-speed formatting of the hard drive or some drive from complete. You can also find out what type of formatting must be applied to the current situation. There will be information on formatting solid-state drives.
All below, the described can be used for recent versions Windows Ourser, starting with "seven". In other version, formatting occurs otherwise.

Differences of the speed and deep formatting of the drive

To find out the difference between the speed and deep formatting of the media in the OS, you need to know which operations occur in each option. Only formatting will be described using integrated operations.

Among them, you can highlight the formatting of the conductor tools. In this case, you need to click PCM on the disk and select "Formatting". You can also use formatting through "Disk Management" of Operations. Here you need to click on the PCM on the section and select "Format".

In addition, you can use the Format command in DiskPart. To conduct high-speed formatting in the command string, for this you need to apply the Quick parameter. If you do not enter it, then complete formatting will be performed. Also, formatting can be performed in the installation utility of the Operations.

Now you can consider how fast formatting is different from full, and what happens to the drive in each of these types.
With high-speed formatting, the boot sector and an empty table of the specified file system are entered. In this case, this space is noted as unused, while actually data from it is not deleted. High-speed formatting requires less time than the complete one and the same media.

When carrying out deep formatting of the drive, except for all the indicated manipulations, zerule is recorded in each disk sector. In addition, there is a disc scanning to the presence of defective sectors. If these are detected, then the correction is performed or they are noted in a certain way so that they do not record on them in the future. This formatting passes for quite a long time, especially on bulk hard drives.

Mostly for simple cases, among which a quick cleaning of the drive for subsequent use, the reinstalling of the Operations and other similar situations can be used quick formatting. But sometimes it may be complete.

When and what formatting is applied

As noted above, in the bulk of cases it is better to use high-speed formatting, but sometimes deep formatting may be preferable. Separately, it is necessary to consider the formatting of simple hard drives and portable drives, as well as solid-state disks.

If you need to give someone a drive, but there is no certainty that the user does not try to restore the remote data, then it is worth using full formatting. If you quickly formatting, you can restore information quite easily.

If necessary, check the disk or after quick formatting, and copying data passes with errors, it can be assumed that there are damaged sectors on the disk. In this case, you can conduct manual scanning of the drive to damaged sectors, and then use fast formatting.

Formatting solid-state drives

Separately, it is worth considering the formatting of solid-state drives. In the case of these drives, it is best to use quick formatting instead of complete. If you quickly format a solid-state drive in a modern operating system, then it will not be possible to restore the data. Already in the "seven" for such media, the Trim command is used for formatting.

Conduct deep formatting and recording zeros is not recommended for solid-state carriers. But modern Operations are unlikely to perform it with a solid-state drive, even if you specify deep formatting. But this is only an assumption, so there is no complete confidence. Although the developers could provide this.

Here, in principle, all information regarding the formatting of ordinary and solid-state drives. It will be easier for novice users to figure out when needed quick formatting, and when complete.
