This means no other diskmanagement utilities (like Windows Disk Management utility) can access it at that time. If you receive amessage stating that the volume cannot be blocked, close the disk management applications that use thisvolume and start again. If you can not determine which applications use the volume, close them all.6.11.6.1. Creating a volumeYou might need a new volume to:• Recover a previously saved backup copy in the “exactly as was” configuration;• Store collections of similar files separately — for example, an MP3 collection or video files on aseparate volume;• Store backups (images) of other volumes/disks on a special volume;• Install a new operating system (or swap file) on a new volume;• Add new hardware to a machine.In Acronis Disk Director Lite the tool for creating volumes is the Create volume Wizard.Types of dynamic volumesSimple VolumeA volume created from free space on a single physical disk. It can consist of one region on the diskor several regions, virtually united by the Logical Disk Manager (LDM). It provides no additionalreliability, no speed improvement, nor extra size.Spanned VolumeA volume created from free disk space virtually linked together by the LDM from several physicaldisks. Up to 32 disks can be included into one volume, thus overcoming the hardware sizelimitations, but if at least one disk fails, all data will be lost, and no part of a spanned volume maybe removed without destroying the entire volume. So, a spanned volume provides no additionalreliability, nor a better I/O rate.Striped VolumeA volume, also sometimes called RAID 0, consisting of equal sized stripes of data, written acrosseach disk in the volume; it means that to create a striped volume, a user will need two or moredynamic disks. The disks in a striped volume don’t have to be identical, but there must be unusedspace available on each disk that you want to include in the volume and the size of the volumewill depend on the size of the smallest space. Access to the data on a striped volume is usuallyfaster than access to the same data on a single physical disk, because the I/O is spread acrossmore than one disk.Striped volumes are created for improved performance, not for their better reliability - they donot contain redundant information.
