8. When you??™re finished customizing, go to File ??? Save to save your custom
console view into a new .msc file such as Disk Management.msc.
The next time you use Disk Management, just open your custom .msc file
instead of diskmgmt.msc to use your customized tool.

Performance
In the Graphical View, you??™ll see different kinds of partitions; here are the
most common:
Primary partition
Most partitions are of this type. If you have more than one partition, the
first usable partition (one that can hold data) is almost always a primary.
Primary partitions are marked with a dark-blue stripe by default.
The old-school approach is to have only one primary partition, followed
by an extended partition (discussed next). This is no longer
needed for NTFS volumes; in fact, if you??™re setting up a dual-boot system,
each OS must have its own primary partition.
Extended partition
The extended partition is a holdover from earlier days, and was used
when a drive had two or more partitions. It doesn??™t actually hold data, it
merely serves as a container for one or more logical drives (discussed
next). Extended partitions and logical drives are more or less obsolete
today (Vista??™s Disk Management tool can??™t even create them), but you
may see them on older partitioned drives. The extended partition is, by
default, shown as a dark-green outline surrounding any logical drives.
Logical drive
If you have a drive with an extended partition, each volume inside is
called a logical drive.
