Basic disc and dynamic disc are the two basic hard configuration types in Windows System. Most personal computers use basic s which make the management easy. Advanced users and IT administrators may use dynamic s which are used to improve the performance of computers with several hard s. The basic uses primary partition, extended partition and logical partition to manage the data on the . The formatted partitions is also called volume (volume sometimes can be exchanged with partition). In Windows, the basic can have four primary partitions or three primary partitions, one extended partition. The extended partition can contain several logical partitions. The partitions on basic s can not be share or split data with other partitions. Each partition on basic is an isolated unit on the . The dynamic can contain about 2000 dynamic volume with the functions like that of the primary partitions on the basic . In some versions of Windows, several independent dynamic can be joined together to form a Spanned Volume, and data can be splitted into several hard s called Stripped Volume to improve the performances, or to make mirror partitions of multi s to form mirrored volume. The function of Convert Dynamic to Basic is to convert dynamic into basic . This function can only convert the simple volume and mirrored volume. The other types of volume can not support the convert operation. While using this function, no other pending operations are required, after the operation is done, users can only convert other dynamic s into basic . Other functions would be invalid after you click apply button or discard to carry out the convert process. Moreover, we suggest that user uses the windows version of Partition Wizard to finish this operation. Because the windows version of Partition Wizard shall ensure the drive letters do not change after the convert. If users use Partition Wizard Bootable CD to carry out the convert process, the drive letter may change, and which will lead to improper boot of system. (Before convert) Windows 2000 introduced the concept of basic and dynamic , and add them to the Windows system administrator tools.The most obvious difference between the two operating system support.All Windows DOS even basic , support for dynamic is not so.Late only Windows version, including Windows 2000, Windows XP, Windows Vista, Windows 7/8 and the version of server system to support dynamic . One can be made of ms-dos and all physical access based on Windows operating system.Basic can contain as many as four primary partitions, or three primary partition to add an extended partition with multiple logical drives.Basic and dynamic is two kinds of hard configuration type of Windows.Most personal computers are configured for basic , this type is the most easy to management.
