      How to partition the unallocated disk space in Windows 7


      In Windows 7, the built-in disk management tool can be applied to partition the unallocated disk space.


      The above symptom may occur on the following operating systems:

      Microsoft Windows 7 Home Premium/Home Basic/ Enterprise/Professional/ Ultimate/ Starter




      Step 1: shrink local disk C or other local disks (temporarily the disk to be is labeled as "X")

      In some cases, it may be necessary to adjust the total capacity of "X". If the capacity is too big, it leads to other disks with less capacity. This problem can be resolved through the "Shrink" feature in disk management tool.

      1. Click "Start", right-click "Computer" and select "Manage". See Fig.1.


      2. In Window "Computer Management", expand "Storage" in the left panel and click "Disk Management". Then, the disk management tool will be loaded in the right panel. In the management interface, right-click the partition X and select "Shrink Volume". See Fig.2.


      3. Then, the disk management toll will query the available shrink space, and the time needed as well PC hardware performance and disk space automatically. See Fig.3.


      4. With the completion of querying, dialog "Shrink" will appear and present some detail information. In default, the disk management tool will enter the maximum amount of space to shrink in MB automatically while the value can be adjusted accordingly. With the confirmation of amount to shrink, click "Shrink" and the partition will be shrunk. See Fig.4.


      5. A moment later, you can see the shrunk partition and the released unallocated space the amount of which is identical with the set amount during shrinking.


      Step 2: create new disk partition

      1. Right-click the "Unallocated Space" of "Disk 0" (in case of the second HDD, it should be "Disk 1" and the rest can be done by the same manner.) and select "New Simple Volume". The following dialog "New Simple Volume Wizard" will appear and click "Next". See Fig.6.


      2. Space volume size interface will appear. See Fig.7. The minimum space allowed by Windows to create is 8MB and there is no upper limit (if there is enough space to allocate). Here, the unit is MB. The user can allocate the space accordingly. Then, click "Next".


      3. The interface of "Assign Drive letter or Path" will appear. The user is required to assign the driver letter or path. See Fig.8. Then, click "Next".



      Three forms of allocation are available for the users:

      (1) If the user needs to create a new partition, he/she can click on the "Assign the following driver letter" and select one letter to replace. He/she also can choose by default.

      (2) If it needs to add a new partition into a disk or folder, check "Mount in the following empty NTFS folder" and click browse button to choose or build a blank folder to load.

      (3) If the user does not want to assign letter for a new partition, he/she can check "Do not assign a drive letter or drive path".

      4. "Format Partition" interface will appear. User is required to format the newly built partition. With the completion of format settings, click "Next". See Fig.9.



      To make available, the user must format the partition. Here, choose "Format this volume with the following settings:

      (1) File system: the file system refers to the bottom file system format and there are two options: "NTFS" and "FAT32". You can choose the default "NTFS".

      (2) Allocation unit size: this option is used for setting allocation unit, namely, set "cluster" size. If the unit will store large files, users can set this unit a little bit big as the appropriate setting can bring better disk performance; if it is used to save small files, set a smaller amount for it to save space. Generally, you can choose by default.

      (3) Volume label: refers to partition name, for example, "Local disk" and so on, the user can set up on its own.

      (4)Perform a quick format: checking this option can complete the partition much faster. It can build the new file table without the need of completely erasing the contents of the hard drive (erasing does not exist for the newly purchased disk).

      (5) Enable file and folder compression: check this option if "NTFS" for file system is chosen.

      5. The interface of "Completing the New Simple Volume Wizard" will appear and present the settings for partition creation. See Fig.10.


      6. In case of anything improper, you can click "Back" to modify. After confirming every setting, click "Finish" and the system will create the partition. With the completion of creation, system will link to the new partition automatically and possibly the following dialog will appear. The user can choose to operate or close it.

      Too many partitions may lead to Lenovo OneKey Recovery failure. Two or three partitions are recommended.
