How to Partition a USB Drive in Windows 10
There are also different USB partition tools available in the market to perform partitioning without getting into Disk Management. Let’s see how to partition a USB drive in Windows 10 using the three ways mentioned below.
1. How to Partition a USB Drive Using Diskpart Command
Note: You need an Admin account to partition your flash drive successfully.
If you want to access the diskpart command to partition your USB drive, use the command prompt.
Press Windows key + R, type cmd and click on OK to open the command prompt.
Once it opens, type diskpart and press Enter.
You need to hit Enter after every command you type.
Now a new window opens, which looks similar to the command prompt, type list disk to list all the available drive on your system.
Select the flash drive to partition.
Use command select disk * (here * means the disk no, it is 1 here, but it can be different for your system) to select the disk.
Once the disk is selected, it’s essential to clean the partitions, if present before.
You can use a clean command to carry out the task.
Now create partition by specifying the size in MB.
For example, let the size of partition be 3GB, so type the command as create partition primary size=3000. To create the file format of type FAT32, use the command format fs=fat32 label=’FAT32’.
Here, the label is optional, as it is just used to give a name to the new volume.
To assign a letter to the new volume created type assign letter=j
Now, use an active command to mark the current partition as active.
To create a partition of remaining space use command creates partition primary.
Follow the same procedure as above to create NTFS file type with a slight change in command, format fs=ntfs label=’ntfsfile’.
Assign the unique letter and use list vol command to see the change.
