What is the difference between formatting and deleting, and what is the difference between formattin

Deletion is just the content of your computer's hard disk is temporarily deleted, delete the file in my ** station after deletion, and then empty there to really delete, but it is not really deleted, if you use recovery software can still recover, that is to say, you use deletion to delete files, your deleted files still have memory in the hard disk, and the memory can still be recovered, and with formatting, it is equivalent to a complete deletion, which can delete all files including viruses. And it can have a certain repair function on your hard disk. But some experts can still recover your formatted files.

Formatting can be understood as quick deletion.

For example, if you have 10 GB files on your hard drive, it may take a long time to delete them, but if you use formatting, you can do it in a few seconds.

If formatted, tracks and sectors are re-established on the corresponding drive to store the data. Deletion operations do not.

If you don't write anything to the formatted drive, the formatted data can be retrieved by other means. The same goes for deletion.

Formatting is to empty all the contents of the hard disk or USB flash drive, if there is a virus, this can also be antivirus. When deleting, clear the contents of the hard disk or USB flash drive, but some files are difficult to delete, if they are poisonous, they may be infected with viruses next time you put something in.

Yes !Deletion is just the deletion of the original thing, and formatting is the deletion of some things will be written into some things!

Formatting is for the entire drive letter.

The deletion is primarily for a file.

However, sometimes formatting can be useful for quickly deleting an entire drive letter file.

Deletion may seem like deletion, but it's not! All that's removed is its directory!

Formatting can be said to be completely deleted!

It's better to understand it this way!

There is a difference.

1. Hard disk formatting is to format the entire hard disk and completely empty it, including hidden files, redundant files, etc. You can also change the formatting type, such as NTFS or FAT32. Formatted disks cannot be restored.

Directly deleted files can be restored by 3rd party software (as long as the deleted files are not overwritten by new files).

2. Formatting is to establish tracks and sectors in the disk, and only after the tracks and sectors are established can the computer use the disk to store data. Deletion refers to the deletion of a file from the system's directory inventory.

3. After formatting the hard disk, all the files in the disk will no longer exist, and the system needs to be rebuilt; Delete everything on the hard drive and do nothing else to get back files or restore the system.

First, the operation is different.

1. Hard disk formatting: refers to an operation that initializes a disk or a partition in a disk.

2. Direct deletion: It refers to deleting the files that are no longer needed from the directory list of the system to free up disk space for other operations.

2. The deleted content is different.

1. Hard disk formatting: Hidden files will also be deleted at the same time.

2. Direct deletion: Hidden files will not be deleted.

Third, the process is different.

1. Hard disk formatting: clear the data on the hard disk, generate boot information, initialize the FAT table, mark logical bad sectors, etc.

2. Direct deletion: just delete the data on the hard disk.

Formatting means to empty.

Formatting and erasing is to zero the data of the hard disk, that is, to delete all the data and files of the hard disk, and restore the hard disk to its original state, and return you to a clean hard disk. At present, the most commonly used hard disk format is NTFS format and FAT32 format, and the general format is divided into ordinary format and fast format, and the fast format is much faster.

Quick format is just a quick way to delete all the things in the partition, if there is no virus problem, it can be done and save time. But if there is a virus problem, it will not work, some stubborn viruses can not be removed by such a quick format, and they should be formatted normally, so that the hard disk can be cleaned thoroughly little by little. Usually the computer system optimization and maintenance only need to use the quick format, if your hard disk data is more confidential, it is to use the normal format.

An introduction to low-level formatting

Low-level formatting is a physical-level formatting, which is mainly used to divide the cylinder of the hard disk, establish the number of sectors, and select the sector spacing ratio. The hard disk needs to be formatted at a low level before it can be formatted at an advanced level, and the hard disk that has just left the factory has already undergone a low-level format, so there is no need for users to format it at a low level.

For example, if you have too many bad sectors on your hard drive, which often leads to errors when accessing data, or even if the operating system is not usable at all, then you need to perform a low-level format. In addition, if some parameters related to low-level formatting on your hard disk are corrupted by viruses, such as the hard disk interval factor, then you have to perform low-level formatting to re-establish these parameters.

First of all, the hard disk that cannot format the content being called in the boot state, this certainly includes the system! But in DOS or non-Windows (such as the installation disk boot), it can be formatted, and everything that will delete the computer (the disk you formatted) can of course be recovered, but it is not necessary.

Formatting is an initialization operation on the hard disk before use, and all the contents on the hard disk will be erased. If you want to format the C drive, make sure you have a system installation disk and copy all important personal information (documents, **, game saves, etc.) to another drive (i.e. backup).

Formatting is the operation of initializing a disk or partition in a disk, which usually results in the removal of all files in the existing disk or partition. Formatting is usually divided into low-level formatting and high-level formatting. Unless otherwise specified, formatting a hard disk is usually referred to as advanced formatting, while formatting a floppy disk usually includes both.

It is to clear the data on the hard disk, generate boot area information, initialize the FAT table, mark the logical bad sectors, etc. Generally, when we reinstall the system, we use advanced formatting, which is to initialize the disk, so that we can record it on the disk step by step.

Delete: Delete: Refers to the deletion of files from the system's directory list, but in many cases, with software or Windows that comes with it"Stations"To be on the safe side, it's a good idea to make a floppy disk backup of the text or other files you enter, just in case.

Every file stored on a hard drive can be divided into two parts: the file header and the data area where the data is stored. The file header is used to record information such as file name, file attributes, and occupied cluster number, and the file header is stored in a cluster and mapped to the FAT table (File Allocation Table).

The real data is stored in the data area. The usual deletion is actually to modify the first 2 ** of the file header, this modification is mapped in the FAT table, which marks the deletion of the file, and clears the registration item of the cluster number occupied by the file in the FAT table, indicating the release of space, which is the reason why the hard disk space increases after the usual deletion of the file.

From the principle of file deletion, it can be seen that the only way to completely delete data is to completely overwrite the data area where the deleted file is located. This is the principle used by most complete deletion tools: to write useless data repeatedly into the data area of the deleted file and overwrite it multiple times to achieve the goal of completely deleting the file.

Formatting is divided into regular formatting and quick formatting.

When you run the regular format command, each sector on the partition is marked as free and available in the file allocation table of the current partition, and the hard disk is scanned for bad sectors, and each sector is marked as usable during the scanning process. The job of scanning for bad sectors takes up most of the time spent formatting a disk partition.

Whereas Quick Format, then only the deletion mark will be made from the partition file allocation table, and the disk will not be scanned to check for bad sectors. Only if the hard disk has been formatted before and the hard disk is not damaged, the normal deletion is to delete the files in the system directory, but the software can be used to restore them.

The result of quick format is basically the same as the result of full deletion, the only difference is that quick format also rewrites the PBR and root directory, while total deletion does not do these things. Quick format is quick to complete, but complete deletion is partial deletion, and if there are a lot of files and folders on the disk, the process will take a certain amount of time.

In addition to quick formatting (rewriting PBR, rebuilding cluster assignments, creating new directories), full format also reads and writes all clusters on the disk, and marks unreliable clusters as unavailable in cluster allocation.

The complete deletion of files on external computer memory media (floppy disks, hard disks, USB flash drives, zip disks) is tombstoning: the file is marked as deleted in the directory, and all the clusters occupied by the file are marked as unused in the cluster assignment. If new files are archived thereafter, it will be possible to use these clusters marked as unused.

So make sure to get back all the deleted files and be sure not to save new files.

Formatting is to restore the disk to the state it was in when it was just bought and there is nothing, and deletion is to delete the files inside, which are two different operations. Deletion can only remove the contents of the file and free up disk space, while formatting not only frees up disk space completely, but also initializes the disk and fixes some of its errors. Of course, if you choose Express Format, it's no different than deleting everything.
