Do you want to partition a USB Or SD Card? Disk Management is a stock utility program in Windows. However, it can manage drives and create a division of your hard drive.

Simply move to the command line and even then, only one partition appears in File Explorer due to Windows didn’t support several partitions on USB drives and SD cards. In this article, we’ll discuss how you can partition a USB or SD card with disk management in Windows 10.

Partition A USB Or SD Card

Step 1:

Insert the USB drive you like to partition. We divide an 8GB USB for this guide. The USB was blank and currently formatted and that’s the best and secure way to go. Make sure if you have data on your USB, then it’s a good idea to create back up elsewhere.

Step 2:

Then open Disk Management in Windows search. You will also view your USB appear in the list of drives. Right-tap it and choose “Shrink Volume” from the context menu.

Step 3:

Choose the size of the partitions you like to make. You can accept the recommended disk size, or you can input a custom one. While having files in the drive, it can’t allow you to shrink the drives down to a size where the files can’t fit inside either one of the drives. That is why it’s good, to begin with, an empty USB or SD card.

Step 4:

It doesn’t take long to divide the drive. Once done, you will view your USB or SD card in Disk Management. At this point, you will only view one partition while the other will seems as an unassigned space.

Step 5:

Right-tap the unassigned space and choose “Create Simple Volume” from the context menu. Just follow the on-screen step and don’t modify anything under the size options. Simply leave them as they are automatically set. When asked, choose a letter to assign the drive.

Step 6:

However, on the Format Partition screen, choose ‘NTFS’ from the File system dropdown. Unmark the quick format option and enable Disk Management to format the drive. Once done, you should view the 2nd drive appear in File Explorer.

Drive Is Not Visible

In the event, the 2nd partition of your USB can’t visible in File Explorer. Simply attach your USB to your system and open Disk Management again. Then you’ll view two partitions under the one USB. It will likely say the 2nd partition is RAW.

Right-tap it and choose the Format option from the context menu. You only want to remember a full format is done and that the files system it is divided on is NTFS. Once the partition is formatted, it will no longer appear as RAW space. Again, right-tap it and choose “Change Drive Letter and Path” from the context menu.

Now assign the drive a letter and you’re done. After you assign the letter to the drive, File Explorer will display you the 2nd partition.
