How to Partition an SD Card in Windows XP
SD cards are a type of flash memory. (sd cards image by timur1970 from

By default, Windows XP does not allow a user to add partitions to removable storage devices such as jump drives or SD cards. You can, however, use a tool called a Windows enabler program that opens up this ability in Windows XP so that you can partition your SD card using the standard Windows disk management feature. With disk management you can create multiple partitions on an SD card or delete current partitions. Creating a partition on an SD card in Windows XP is a straightforward process that you can accomplish in a few minutes.

  1. 1

    Download and install a Windows enabler program. This program runs in the background while you normally operate Windows and allows you to access "grayed out" features that Windows XP normally will not allow a user to access.

  2. 2

    Connect the SD card to your computer using an external card reader or the integrated card reader, if your computer has one.

  3. 3

    Click "Start" and click "Run." Enter "compmgmt.msc" and click "OK" to open the Windows computer management interface.

  4. 4

    Click on "Storage" in the left column and then select "Disk Management" beneath it.

  5. 5

    Right-click the SD card in the list of disks in the bottom right and click "Delete Partition." A dialogue box will appear. Click "Yes." Note that this will erase any saved data on the SD card, so back up the files if necessary before you perform this function.

  6. 6

    Right-click the now "Unallocated" SD card and click "New Partition." The "New Partition Wizard" will appear.

  7. 7

    Select "Primary partition" and click "Next."

  8. 8

    Enter the desired size of the partition using the up and down arrows in the "Partition size in MB" field. Click "Next."

  9. 9

    Select "Format this partition with the following settings." Choose "FAT" for the "File system," "Default" for the "Allocation unit size" and enter a name for the disk into the "Volume label" field.

  10. 10

    Place a check mark next to the "Perform a quick format" option and click "Next." Windows XP will create a new partition on the SD card.

  11. 11

    Repeat this process on the remaining unpartitioned space.

Tips and warnings

  • Using a Windows enabler program can cause you to accidentally perform functions that can damage your computer. Disable the Windows enabler program when you don't need it by right-clicking the icon in the task bar and selecting "Exit."
