How to remove / delete partition from external
hard drive? In this tutorial, you can learn three methods to remove partitions
from external HDD in Windows 10/8/7.

Remove / delete partition on external hard
drive

A partition on an external hard drive can be
deleted or removed as long as it is not currently in use. For instance, if
operating system is installed on the partition you want to delete and the
system is running, you cannot delete it. While in most cases, external hard
drive is mainly used as secondary disk for data storage, thus you can easily
delete partitions when necessary.

“I just bought a 1TB external hard drive which comes with a small partition of 300MB which is shown as EFI partition and a large partition with rest capacity in Windows Disk Management. I want to delete the small partition and add the space to that large partition, so that I can make use of the entire disk space. When I right-click on the small partition in Disk Management, the Delete option is greyed out. Does that mean this partition cannot be deleted? Is there any possible method to remove the partition from external HDD or combine it to the other partition? I’m using laptop with Windows 10 Home installed. Thanks in advance.”

Disk partitions works as data containers which
stores various files, installs operating system or programs or keeps backups.
As time goes by, the amount of data on external hard drive keeps increasing and
changing. Partition deletion removes the partition as well as files in the
volume. Since external disk may keeps important data for you, why do you still
need to remove or delete partitions? Here are some common reasons of deleting a
partition.

  • You want to reduce the number of partitions on
    the disk. Your disk may not be partition properly, for example, there might be
    too many partitions on the disk. Thus, deleting partition can help manage data
    in a simpler way.
  • To gain unallocated free disk space. Once a
    partition gets deleted, disk space taken by the volume will turn to unallocated
    or free. Free disk space can be added to current partition or create a new
    volume.
  • In order to repartition external disk. Deleting
    all partitions on the disk helps to get free space, after which you can create
    new partitions based on your requirements.
  • To free up disk space. Some users want to
    delete OEM partition, or recovery partition to free up disk space, although
    such partitions take very little space.

Note: Once a partition gets deleted, files and folders on the volume also get deleted. Remember to backup any data you want to keep before deleting any volume.
