After learning how to undo quick format, let's talk about some basic information about the quick format.

Overview of Quick Format

1. Quick format VS. Full format

In general, when you format a hard drive or partition, you have two options: quick format and full format. However, do you know what the difference between them is?

quick format vs full format

Some users say: "the only difference between the full format and the quick format is whether the volume is scanned for bad sectors by using the CHKDSK command or not. A quick format will not scan the disk for bad sectors while full format can do it."

Is that true? For more information, please see the following part.

Quick Format

A quick format is just that, quick. To make the formatting process quick, the drive is not checked for bad sectors. And a quick format will only delete the journaling part of the file system , and then lay a new, simple, and blank file system on top. ( NTFS , ext3, and ext4, as well as HFS+ are all journaling file systems .)

So, anyone looking at the hard drive or storage device would not see any data. Fortunately, these files are actually still there and users can recover them as long as they find reliable free quick format recovery software like MiniTool Power Data Recovery. So normally a quick format is what you want because it is much faster.

Full Format

A full format is almost the complete opposite of a quick format and is generally preferred over a quick format. Full format runs an additional step that checks the hard drive for any bad sectors.

Accessing each sector on the disk takes much more time than the quick format, which only writes the blocks that contain the file system structure.

Besides, a full format completely wipes your hard drive. After a full format, there is a little chance to recover missing data even if you use data recovery software or ask the professional person.

2. A Few Causes for Performing Quick Format

Mistaken operation: There is no doubt some users might accidentally quick format a partition or drive instead of some other drives. For instance, you were going to format E: drive, however, you formatted F: drive by mistake.

Error messages: Sometimes, you are unable to access a drive and receive an error message that says You need to format the drive before using. So, you format it without hesitation.
