USB Has Two Partitions Issue

"I have a 16GB Kingston flash drive that has been accidentally partitioned. The USB drive split into two parts, and now my USB has 2 partitions, with 7.3GB each. I've tried to delete one partition or combine the two partitions into one with Disk Management, but all failed. How can I work out the problem?"

Plugging into your USB drive with several gigabytes of storage only to see two or multiple partitions pop up in the Windows File Explorer? You may ask, can a USB drive have multiple partitions? Yes, as long as you meet the following two conditions, you can create two or more partitions on the USB.

1. Make sure your computer is running Windows 8.1 and later that supports the recognition of multiple USB flash drive partitions.

2. Your USB is generated by a specific vendor and supports the creation of multiple partitions.

Multiple partitions on one USB drive lead to a lot of unnecessary memory consumption, and it's really inconvenient. Facing this issue, you can't resolve it by simply reformatting as you can only reformat each individual partition instead of the whole disk drive. Then, it leaves you with two options to troubleshoot: one is deleting partitions on the USB drive, and the other is merging USB partitions. First, we will show you two ways to delete a partition on the USB drive with easy partition management software and Diskpart. Move to check details. 

Use an Easier Partition Manager to Delete a Partition on a USB Drive

Don't have confidence in using Command Prompt well? Some people with a little technical background may try to avoid using diskpart utility because of the complex operation. More importantly, they're afraid of making trouble with wrong commands and doing damage to their hard drive data. Apart from human factors, you might encounter an error called 'diskpart cannot delete a partition on removable media' from time to time, which makes you give up the Dispart. In all these cases, how do you remove all partitions from a USB drive/SD card easily? It is a wise choice to choose an easy-to-use partition management software as a workaround. 

EaseUS Partition Master, much more powerful than Diskpart and Disk Management in Windows 11/10, provides a wide range of disk organization functions and enables you to delete partition, format partition, hide partition, wipe partition, clone/copy partition, combine/merge partitions effortlessly. It goes fully compatible with Windows 11/10 and has advanced partition management features that are unavailable in diskpart utility, such as migrate OS to HDD/SSD.
