Basic disks rely exclusively on the MBR-style partitioning scheme Basic disks rely exclusively on the MBR-style partitioning scheme Dynamic disks are partitioned using Logical Disk Manager (LDM) Dynamic disks are partitioned using Logical Disk Manager (LDM) 3 Windows has the concept of basic and dynamic disks Dynamic disks implement a more flexible partitioning scheme than that of basic disks

Basic disks are the storage types most often used with Windows Windows manages all disks as basic disks Windows manages all disks as basic disks Unless you manually create dynamic disks or convert existing basic disks to dynamic disks Unless you manually create dynamic disks or convert existing basic disks to dynamic disks 4 Microsoft recommends to use basic disks unless you require the multi-partition functionality of dynamic disks
