Resize Your Hard Drive Partition Without Losing Data

Posted on: 12/14/10

Most computer vendors sell PCs with large storage capacities but with just a single partition. You may find that you have to change the partition size to increase or decrease the space on a particular drive. Resizing the partition size on a drive can be risky – you may lose or mess up the stored data.  Here is the most effective and safest way to resize your hard drive partition without losing any data.

  1. Right click on the My Computer icon, and select Manage



  2. In the console tree, click Disk Management.



  3. When you resize a partition, you choose to either expand or shrink the volume size. Please note that when shrinking the volume size, you must have enough empty space on the current partition. If you want to expand a volume size, make sure the hard drive has enough unallocated space available. To expand the size of the partition, right-click on the partition and select ‘Extend Volume…’.



  4. Follow the ‘Extend Volume Wizard’, and type in the amount of space you would like to increase the volume by ‘Select the amount of space in MB:’.  Click the ‘Next’ button.



  5. If you wish to shrink a partition, right-click on the partition and select ‘Shrink Volume…’.



  6. The Disk Manager will then calculate if there is enough space to shrink the volume. If you have enough space, a dialog box will appear where you will be able to see the shrink space available. Enter the amount of space to shrink and hit the Shrink button.



Note: The above guide is intended for Windows Vista or Windows 7 users.  If you have Windows XP or older Windows operating systems, you will need a third party program like Partition Wizard to expand or shrink hard drive portions.
