Partitioning a computer's hard drive depends more on your operating system than the computer's make or model. Windows Vista and Windows 7 -- both of which came pre-loaded on the Acer Aspire One notebook -- allow you to repartition your drives on the fly. Aspire One notebooks come with different hard drive sizes, but the process for partitioning the drive in Windows is always the same.

Skill level:
Moderately Easy


  1. 1

    Log in to your computer as administrator. If you only have one user account, the default user (you) is an administrator on Windows by default. Click "Start," and then choose "Control Panel." Click "System and Maintenance," and then click "Administrative Tools." Double-click "Computer Management" to open the Computer Management application.

  2. 2

    Click the arrow beside "Storage" to expand the category, and then click "Disk Management" to see all of the fixed volumes and partitions on your computer. You might see more drives in this list than in Windows Explorer, including the hidden Acer recovery partition. The top half of the Disk Management window shows your assigned drive letters, and the bottom half shows your physical drives. The Acer Aspire One should be configured as follows: a "Disk 0" with three or four partitions and a "CD-ROM 0."

  3. 3

    Check for free space to ensure that you can create a new partition. Look at the bottom half of Disk Management to see how your partitions are currently allocated. Your Aspire One will have a small "System" partition that you can't change, a "C" partition with most of your storage space, a "D" partition for recovery (which you shouldn't change) and possibly a fourth position called "Backup." Not all Aspire Notebooks have the fourth partition.

  4. 4

    Right-click on "C:", and choose "Shrink Volume" to create a new partition using the free space on your C drive. You can do this with your backup drive too, if you have one. Wait a few minutes while Disk Management calculates how much space you have to put toward a new partition. The program automatically chooses the maximum available size, but you can choose a different partition size if you like. Enter the size in megabytes, and then click "Shrink."

  5. 5

    Format your newly created partition so that you can save files to it. Right-click on the new partition in Disk Management, and choose "Format." Type the name of the volume, and then choose a file system type -- FAT32 or NTFS -- and click "Format." When the process completes, you'll be able to see your new partition in Computer and use it for storage.
