Resize Partitions With Vista Disk Manager

Windows Vista Tips & Tricks: Resize Partitions With Vista Disk Manager

The release of Windows Vista will bring a number of welcome enhancements to the built-in set of system tools, including the ability to dynamically resize partitions. Prior to Windows Vista, the ability to shrink and extend disk volumes has only been available through third party tools such as Partition Magic.

Although not as full featured as some third party partition management applications, Windows Disk Management console will allow users to shrink, extend, create, and format partitions. The new resizing features will allow users to shrink a single partition with unused space, and then create a new partition in the resulting free space, as well as extending a current partition if there is available free space after it.

To access Disk Management, right click on My Computer, and select Manage from the context menu – this will open the Computer Management console (alternatively, Disk Management may be accessed from Control Panel> Administrative Tools> Computer Management).

From the Computer Management console, click on Disk Management which is located under the Storage section in the left hand pane. To shrink a current volume, locate the partition to be resized from the Disk Manager, right click on it, and from the context menu select Shrink Volume.

A Shrink dialog box will open from which you can enter the amount of space in MB to shrink the partition. This dialog box will also show the current size of the partition, the size of available shrink space available, and the total size after shrinking. Once you have selected the amount of space to shrink the partition by, click on the Shrink button.*Note: the size of the available shrink space can be restricted due to page files, restore files, and hibernation files.

Once the Shrink operation has completed, you will now have the selected amount of unallocated free space available immediately following the shrunken partition.

To extend a current volume, locate the partition to be resized from the Disk Manager, right click on it, and from the context menu select Extend Volume. The Extend Volume Wizard will then open, click Next. You will then be given a dialog box to select the disks to extend. Select the amount of space in MB to extend the volume, and click next. The selected partition will then be extended by the amount of MB selected. *Note: If the partition you want to extend is a boot or system, or cannot be converted to dynamic, you will only be able to extend the volume to the immediately adjacent free space.

Once volumes have been resized, a new partition can be created and formatted in any unallocated free space by right clicking on the unallocated space in the Disk Manager, selecting the type of volume to create, and completing the New Volume Wizard.

With the new enhancements to Windows Vista Disk Management, shrinking and extending partitions is now easily accomplished. As always, when making changing to the partition structure, users should ensure that all important files and data are backed up.

Unmovable files such as page files maybe on the drive. Try disabling virtual memory then try again.

For those who have the "lotsa space but little shrink room" problem, this should help:

It really is that certain data is placed at the end of the disk or partition, and you can move it with the "Offline" files defrag available in the free trial of . I think there are supposedly limitations in the trial program, but what you need works.

If you want to make smaller partitions out of the new ones you make, you have to do defrag "offline" files on each new partition before you'll be able to shrink it. You'll be able to see Perfect Disk move the data. I think in another defragger the data that kept getting in the way was IDed as metadata .

So many experts say that defrag isn't necessary under normal circumstances, but I do like my data tidy. I'm tempted to buy Perfect Disk just because it allowed me to partition my disk using the Vista tool. Plus, I like to see the process, not do it blind as in Vista's defragger.

I tried for 2 hellish days to solve this problem without buying something or figuring out how to install & use GPart. Someone suggested this, but without detail, and I didn't understand that I could use Perfect Disk in a trial version that would work. I'm going to offer this solution in the appropriate threads in the sites I visited when looking for help. Please do the same if you have time.

Hope this helps!
