LDMDump 1.02

Windows 2000 introduces a new type of disk partitioning scheme that is managed by a component called the Logical Disk Manager (LDM). Basic disks implement standard DOS-style partition tables, whereas Dynamic disks use LDM partitioning. LDM partitioning offers several advantages over DOS partitioing including replication across disks, on-disk storage of advanced volume configuration (spanned volume, mirrored volumes, striped volumes and RAID-5 volumes). My March/April two-part series on Windows NT/2000 storage management in Windows 2000 Magazine describes the details of each partitioning scheme.
