To format the drive using a command prompt in Windows, it can be done with the diskpart or format command. 1. When using diskpart formatting, you need to run the command prompt as an administrator, enter diskpart, list disk, select disk X (X is the disk number), list partition, select partition Y (Y is the partition number), format fs=ntfs quick to complete the formatting. 2. Use the format command to directly enter format d: /fs:ntfs (d: is the drive letter) for operation. 3. Fast formatting does not scan bad sectors by default. The quick parameter needs to be removed for complete formatting. Note: Back up data before operation to avoid accidentally deletion; the system disk cannot be formatted using this method; external devices can try to unplug and solve the identification problem.

To format a drive in Windows, using a command prompt is a quick and efficient way to do so, especially if you can't operate through a graphical interface. If you have entered the system or have administrator privileges, you can complete the task by using diskpart or format commands. The following are some common operating methods.

Format drives using diskpart

This is the most commonly used and flexible method, suitable for various file systems such as NTFS, FAT32, etc.

The steps are as follows:

• Open a command prompt (run as administrator)
• Enter the following command:

 diskpart
list disk

• Select the disk you want to operate (such as disk 1):

 select disk 1

• View partitions on this disk:

 list partition

• Select the partition to format (such as Partition 2):

 select partition 2

• Start formatting (taking NTFS as an example):

 format fs=ntfs quick

• Exit after completion:

 exit

Note: Before operation, be sure to confirm that the correct disk and partition are selected, otherwise data may be deleted by mistake.

Use the format command to format directly

This method is simpler and suitable for situations where you already know the drive letter.

For example, format the D disk to NTFS:

• Open a command prompt (administrator permissions)
• enter:

 format d: /fs:ntfs

The system will prompt you whether to continue and ask for the questionnaire label. Enter Y to enter to start.

This method does not support system disk formatting, and if the drive is being used, it will prompt "cannot be formatted".

The difference between fast formatting and full formatting

• Quick Format (default) : Only clears the file system structure, does not scan for bad sectors, and is fast.
• Complete formatting : A comprehensive check of the entire disk will be performed, which takes longer but more thoroughly.

If you want to perform a complete format, remove the quick parameter in the command:

 format fs=ntfs

A few things to pay attention to

• Be sure to back up important data before operation.
• It is not recommended to format the system disk unless you operate in a PE environment.
• If it is an external device (U disk, mobile hard disk), unplugging and trying again can sometimes solve the identification problem.
• Some large-capacity USB or SD cards may be FAT32 file systems by default and require manual NTFS or exFAT.

Basically, that's not complicated to operate, but you have to be careful to confirm every step.
