How to Create, Shrink, Extend or Delete a Hard Drive Partition on Windows 10

Usually, a Hard Drive comes with a single collated storage memory that you may logically divide into separate partitions. People usually partition a hard drive to organize or manage their data into multiple virtual drive volumes.

Partitioning a hard drive is undoubtedly a great way to make the most of all the space you’ve got. You can Create, Shrink, Extend, Format, or even Delete the hard drive data on Windows 10. And, it’s pretty easy. But careful! If you do it wrong, you may end up losing your data forever.

Of course, you don’t want that to happen. So before getting started, take backup of your essential data to prevent data loss. You can use an external storage media drive, such as SSD, HDD, USB, etc., to create the backup.

Once the job’s done, start partitioning your hard drive with the easy DIY methods shared in this blog.

Suppose you need an extra partition to manage your data but don’t have any additional disks. In this case, you may shrink the existing partition from the end of the volume to create an ‘Unallocated’ disk, which can be created as a new partition. Follow the given steps to shrink an existing drive volume:

  e. Space will appear as ‘Unallocated’ in the Disk Management. Now, convert it into a functioning hard drive partition.

C. Steps to Extend a Hard Drive Partition

If you want to add more space to an existing drive partition, you can extend it, but only if there is a partition available with storage but no drive letter or file system assigned to it. Follow the given steps to extend a volume into space directly after the partition on the drive:

Note: The partition you want to extend should also be formatted with the NTFS or ReFS file system.

Sometimes, you may want to increase the size of another drive volume or get rid of the partitions that are no longer in use. To do so, you may clean the storage by deleting the hard drive partition.

Important Note: Deleting drive volume may erase all of your data stored on it. If there are important files that you want to save, take their backup first or recover them using reliable data recovery software. Once you have got your files, you may proceed with deleting the hard drive volume.

Formatting the drive may help you get rid of this error but will end up causing data loss. You may recover lost data using efficient data recovery software.
