Windows 2000 introduces the concept of dynamic and basic storage to Windows storage managers.
"Basic Disk" is Microsoft's term for the sort of disks that have always been found on Microsoft operating systems. Storage and storage management are partition oriented and basically organized around individual hard disks that could have more than one partition. This was, however, somewhat modified by Microsoft's support for concepts like RAID which allowed mirroring or striping across multiple disks. You still need basic disks if you want computers running other Microsoft operating systems such as NT 4.0 or Windows 98 to access the data.
"Dynamic Disk" refers to Microsoft's version of the kind of volume-oriented storage that is familiar to managers of enterprise-level operating systems such as Unix. Volumes can stretch over multiple physical disks and can be resized and otherwise managed without rebooting the operating systems. Dynamic disks are also more amenable to such enterprise-level features as fault-tolerant disk systems.
The one thing you cannot do is include a basic storage partition or logical drive within a dynamic disk volume. They must be kept logically separate and storage managers need to allow for this in planning their storage architecture.

Rick Cook has been writing about mass storage since the days when the term meant an 80K floppy disk. The computers he learned on used ferrite cores and magnetic drums. For the last twenty years he has been a freelance writer specializing in storage and other computer issues.
