As you probably know, Windows NT supports four primary
partitions per physical hard disk, one of which can be an
extended partition. Of course, you can create logical drives
within the extended partition. Windows 2000 (Win2K) follows the
same strategy: You can have a maximum of four primary
partitions, one of which can be an extended partition with
logical drives. However, Win2K supports two new disk
configuration types—basic disk and dynamic disk—which you must
understand to effectively configure and troubleshoot Win2K disk
storage.  Basic Disk  A Win2K basic disk, which is similar to
the disk configuration we're used to in NT, is a physical disk
with primary and extended partitions. As long as you use an
appropriate format, Win2K, NT, Windows 9x, and DOS can access
basic disks. Unlike in NT, you don’t need to commit changes or
restart your computer to get Disk Management changes to take
effect.  Dynamic Disk  A Win2K dynamic disk is a physical disk
that doesn't use partitions or logical drives. Instead, it
