"I have a Seagate hard drive that has 3 partitions. But, now I don't want this configuration and only want the whole drive with no more partition. Can someone please advise how to reformat external hard drive into a single partition? Please help! I’m using Windows 10."
Two ways to format the external hard drive with multiple partitions
Users may want to reformat an external hard drive with multiple partitions so that they can keep only one partition on the disk for different purposes. And, there are two ways from which you can choose to manage the job. Here, I believe you may have a different choice in different situations.
1. Format external hard drive with multiple partitions using disk management
Removing partitions from the external hard drive and creating a new one is the first way you can try! It can be done with ease using disk management without any third-party software.
1) Connect the external hard drive to a Windows PC.
2) Press "Windows+R" to open Run, type diskmgmt.msc in the empty box and tap "OK" to open disk management tool.
3) Right-click the drive and click "Delete Volume".
4) Right-click the external drive again and select "New Partition". Finally, follow the wizard to finish the process.
As you can see, it will erase all your data from the external hard drive. So, you’d better not try this way if you have a large number of important data to be saved. And as an alternative, we recommend you to try a third-party partition software to merge multiple partitions into a single partition.
2. Format external hard drive with multiple partitions using EaseUS partition tool
EaseUS partition software is an excellent tool that works well to partition an external hard drive. It can help you reformat multi-partition external hard drive into one partition by combining partitions. What’s the most important, no data loss problem will occur during the process!
Step 1: Launch EaseUS Partition Master, right-click the partition on your external hard drive/USB/SD card which you want to format and choose the "Format" option.
Step 2: Assign a new partition label, file system (NTFS/FAT32/EXT2/EXT3), and cluster size to the selected partition, then click "OK".
Step 3: In the Warning window, click "OK" to continue.
Step 4: Click the "Execute Operation" button in the top-left corner to review the changes, then click "Apply" to start formatting your external hard drive/USB/SD card.
