Zoning is in essence a formatted hard disk

Zoning is in essence a formatted hard disk. When we create a partition, has been set up all the physical parameters of the hard disk, specifies the hard disk Master Boot Record (the Master Boot Record, Free Partition Magic alternative generally referred to as the MBR) and Boot Record backup storage location. For the file system as well as other information required to operate a system management hard disk by senior after formatting, namely the Format command.
Before installing an operating system and software, first of all need to partition and format the hard disk, and then you can use the hard disk to save all kinds of information.partition manager freeware  Many people would think that since is partition you have to put the hard disk is divided into several parts, in fact, we can only create a partition using all or part of the hard disk space. However, no matter how much we divided the partition, no matter use SCSI hard drives or IDE hard disk, hard disk must be considered the primary partition set as the active partition, such ability can through the hard disk boot system.
General notebook to buy back only a disk C.
1, when the system needs to restore, partition magic server the entire disk C is the system disk is formatted, if the information in the system tray will all disappear.
2, system disk pack too many other things will slow down the speed system.
3, different types of data with the corresponding plate, classify, own good find.
4, after the hard disk partition, the size of the cluster will be smaller. Cluster means can be assigned the minimum disk space to save the file, the operating system rules can only be placed in a cluster of the contents of a file, this file space occupied, can only be the integer times of clusters; And if the file size is less than a bunch of actually, it is also to account for the space of a cluster. So, the smaller clusters, save the information of the higher efficiency
Extended partition and logical partitions:
DOS and FAT file system originally were designed to support the most set up 24 partition on a hard drive, using 24 from C to Z drive letter. But the best partition table in the master boot record can contain four partitions record, in order to solve this problem effectively, DOS partition FDISK command allows the user to create an extended partition, and to build up to 23 in extended partition logical partitions, each of these partitions are assigned a drive letter alone, can be used by the computer as a separate physical device. Information about the logical partition are stored in the extended partition, and the primary partition and extended partition information is stored in the MBR of hard disk. This means that no matter how many letters are there in the hard disk partition, only the master boot record contains primary partitions (also is the boot partition) and extended partition on both sides of the information
