Instructions on how to format the USB simple and safest

- Format USB is a fairly simple task and is usually done by computer users. However, few people really understand the nature of formatting USB and the format options really differ.

The following article will help readers find out how to format the USB best and explain what each format option means and whether they are suitable for your intended use or not.

How to format USB in Windows

Whether you're running Windows XP, Windows 7, Windows 8.1, or Windows 10, the basic steps are the same, specifically as follows:

- Plug in a USB drive.

- Open Windows File Explorer and go to this PC (also known as Computer or My Computer).

- Right-click on the drive and select Format

The format options you can customize are File system, Allocation unit size, USB name (Volume label) and Format (Format Option) option. You can also Restore device defaults in case your custom settings do not work.

To format your drive, simply make your selection, click Start, then OK to confirm that you really want to erase all data and the drive will be formatted.

However, before you proceed with the format, you will want to understand the meaning of each of these options. So let's see what the wall means by choosing one.

What file system should I choose?

In Windows 10, you will see up to four different file systems: NTFS, FAT, FAT32 and exFAT. You will not see FAT and FAT32 options if your drive is larger than 32 GB. Therefore, what is the difference between file systems, let's find out below.

NTFS vs. FAT & FAT32:

- NTFS can read / write files larger than 4 GB

- Create partitions larger than 32 GB

- Compress files and save disk space

- Better space management = less fragmentation

- allow multiple clusters on larger drives = less wasted space

- add user rights to individual files and folders (Windows Professional)

- encrypt files quickly with EFS (Encrypted file system; Windows Professional)

FAT & FAT32 Compared to NTFS:

- Compatible with almost all operating systems

- takes up little space on the USB drive

- less data write operation = faster and less memory usage

exFAT Compared to FAT & FAT32:

- Read / write files larger than 4 GB

- create drive partitions larger than 32 GB

- Better space management = less fragmentation

As you can see, FAT and FAT32 are suitable for USBs smaller than 32 GB and in environments where you never need to store files larger than 2 or 4 GB. In other words, every regular hard drive (60 GB +) must be formatted with NTFS.

However, due to how NTFS works, it is not recommended for flash drives, even if they are larger than 32 GB. This is where exFAT shines. It combines the essential advantages of FAT (small, fast) and NTFS (supports large file sizes) in an optimal way for flash drives.

It should be remembered though that FAT and FAT32 are the only cross-platform compatible file systems. NTFS is supported by Linux, but it requires a hacking application or a third party to work on a Mac. exFAT, on the other hand, is supported since OS X 10.6 (Snow Leopard), but you need a driver to read it on Linux.

If for compatibility reasons or the speed you want to use with FAT or FAT32, always choose FAT32, unless you are using a USB or flash drive with a capacity of 2 GB or less.

What is the Allocation Unit Size that works best?

Hard drives are allocated in clusters and the allocation unit size describes the size of a cluster. The file system records the status of each cluster, which is either empty or already in use. When a file or part of a file is written to a cluster, that cluster is occupied, regardless of availability.

Therefore, larger clusters can result in wasted storage space. However, with smaller clusters, the drive becomes slower because each file is divided into smaller parts and takes more time to connect them all together when the file is accessed.

Therefore, the optimal allocation unit size depends on what you want to do with your USB drive. If you want to store large files on that drive, the larger cluster size will be better as the drive will be faster. However, if you want to store small files or run programs from the flash drive, the smaller cluster size will help conserve space.

General rule: large drives and / or large files = large allocation unit sizes

What is the drive letter (Volume label)?

Volume label is simply the name of the drive. It is optional and you can name your drive your way. However, there are a few rules to follow, depending on the file system you will format.

NTFS:

maximum of 32 characters

no tabs

will be displayed with uppercase and lowercase letters

FAT:

Maximum of 11 characters

Do not have any of the following characters: *? . ,; : / | + = <> []

no tabs

will be displayed in all uppercase letters

You can use spaces, regardless of the file system

What format should I use?

When formatted under normal conditions, the files are deleted from the USB and the USB will scan the corrupted areas. In quick format, only the files are deleted and the USB does not perform scanning. Therefore, choose the Quick Format option if you do not have much time and believe that your USB is still good.
