Many of you have already seen when trying to install an operating system, or when connecting a storage unit as a hard disk to the computer, that there are several types of formatting, however, apart from the time they take, it is not specified what is the Difference between them, especially low level formatting that they do not even show us, and that you should know, since it is very important.


In total there are 3 types of format, are the formatting slow or normal, fast formatting (the most used and shallow) and low level formatting, which as I said above, do not offer us as an option operating systems.

Well, my intention is to be able to explain what the difference between these types of formatting, so that when you format a hard disk or any other type of storage device, you know clearly which you should use and why, which you can See in the following comparison of format types.

Differences between normal, fast and low level formatting:

Normal, slow or complete formatting: This type of formatting, which is usually displayed under the 3 names mentioned, eliminates the files and filesystem of the drive, creating from 0, all the logical structure of the hard disk, it also scans The drive in search of damaged sectors and mark them to not be used, and avoid losing data in a future use, so that this process is slower than a quick format.

Quick formatting: it does not erase the contents of the disk, but it deletes the file system either FAT or NTFS, this logical erasure prevents the normal access to previously saved files, unless we use it for it Deleted files recovery programs. Failing to check for damaged sectors, formatting is done faster, but this causes, attempts to save information in damaged sectors, and can cause data loss, this method I recommend only the first time you use a disk or device Of storage.

Low level formatting: This formatting performs everything that completes the formatting, but in addition, it is also a method through which the manufacturer organizes the way to make the HDD operative, creating a series of marks on the physical surface of the HDD. Disk, which organize the spaces where the user information will be stored.

This type of formatting, repair problems such as bad magnetization of the disk in certain sectors, but never repair a physical disk damage, also erases irrecoverable information, so it is perfect to try to save a disk that gives problems, or to Format a disk before it is thrown, to ensure that no one can recover information that you have saved and deleted on the hard drive before.

* Remember, you must save the data you want from the storage device, before formatting, since all the formatting erase the information stored on the disk, I hope the information has been useful to you, thank you for your visit, and I hope Come back soon.
