This article will explain the differences between quick format and full format and provide advice on how to choose between them. As we mentioned in What Is Disk Formatting , the whole disk formatting process consists of three parts: low-level formatting, partitioning, and high-level formatting.

The formatting operated by computer users is high-level formatting. And this formatting is operated on partitions. However, the high-level formatting is specifically divided into two modes in the actual operations: quick format and full format it is also called general format. The differences between quick format vs. A good knowledge about them will help computer users make best use of disk. First, let's take formatting in Windows Explorer and Disk Management as examples.

When computer users format a partition, quick format is checked by default. If they uncheck quick format, full format mode is selected automatically. Then click Format. Then, right click a partition and select Format. Then, type "diskpart" to open diskpart window.

What is the difference between quick format and full format? Many people are concerned about these questions. To figure out these problems, computer users must know what happens when they format partition with quick format vs. Quick format will "delete" files from the partition and rebuild the file system , volume label, and cluster size. It is faster than full format.

However, it's not the real sense of formatting. Pay attention that I used the word "delete", not "erase". That means that quick format doesn't really erase all the data. It just marks the partition as "formatted" and destroys the journal that keeps tracks of the files and their locations on hard drive.

So, the data is still on the hard drive and it can be easily recovered by a data recovery software before it is overwritten. Full format will clear files completely from the partition, rebuild the file system, volume label, and cluster size, and scan partition for logical bad sectors that's why full format is slower than quick format.

It is the real sense of formatting and that's why some people are afraid of it. In Windows with the versions Windows XP and earlier, full format just had the additional bad sector scanning function compared to quick format.

That means that data can be easily recovered in these Windows operating system even if full format is performed. But full format is changed in Windows Vista and later Windows versions, it will erase original data, write zeros to the whole partition, and finally erase zeroes again to avoid the possibility of data recovery.

So, full format does erase all data. Generally speaking, data that is fully formatted in Windows Vista and later Windows versions will not be able to be recovered by data recovery software. However, some people still think that data can be recovered with more advanced technology through the residual magnetism on disk.
