How to create a Spanned Volume
A spanned volume is a volume that uses more than one physical disk. You can use any unallocated space left on disks to create a spanned volume. It also can include more than one unallocated space on a single disk while free spaces can be of any size. The only benefit of spanned volumes is the use of unallocated space that may have originated from imported disks or specific volume arrangements. The main disadvantage is the risk of losing the volume if one disk participating in the spanned volume fails. A faulty portion means a faulty spanned volume! There are no performance benefits when implementing spanned volumes.
To create a spanned volume, perform the following steps with administrator privileges:
- Open the Disk Management console by typing disk management in the Start search text box and click Create and format hard disk partitions or from the Computer Management console found in Control Panel\All Control Panel Items\Administrative Tools
- Convert disks to Dynamic if they are set as Basic, right-click a Disk (left-hand side) and select Convert to Dynamic – at a later stage, the wizard prompts you to convert disks if you skip this step Read more…

How to create a Simple Volume
In Windows 7 (and Vista) simple volumes are created on basic disks with or without partitions and on dynamic disks when no other disks are available to form a stripe set or spanned volume. Therefore, it is the default volume type that has the basic features such as, extend and shrink volumes! It is recommended to use basic disks with simple volumes if you do not require the advanced features of dynamic disks.
To create a simple volume, follow these steps with administrator privileges:
- Open the Disk Management console by typing disk management in the Start search text box and click Create and format hard disk partitions or from the Computer Management console found in Control Panel\All Control Panel Items\Administrative Tools
- Right click an unallocated space on the new disk and select New Simple Volume – the New Simple Volume Wizard starts
- Specify the volume size in MB – the default is the maximum available space
- The next screen shows the default assigned drive letter, you can set any available letter from the drop-down list, while, you can also create a volume without a drive letter or mount it in an empty folder
- In the next format partition screen, it is recommended to leave the default file system and allocation unit size settings while type in a meaningful name in the volume label text field. If you suspect that the drive may contain bad blocks I suggest you perform a long format (uncheck the Perform a quick format), otherwise do a quick format as the process may take very long especially with large capacity drives. Also, you can enable file and folder compression for this volume
- The final screen is a summary of all set parameters, if no changes are required click Finish
When using the DiskPart command-line tool make sure that you create a partition on a basic disk while a simple volume on a dynamic disk, otherwise the tool fails. The Disk Management snap-in is more intelligent and adjusts itself according to the disk type.
