【 Weak current College 】 hard drive partition formats do you know how many

Hard drive partition formats, there are several? rookie may be unclear. The most commonly used now partition is NTFS, FAT32 format before has gradually eliminated, there are some of the more distant the hard drive partition formats had forgotten.

Faded does not mean useless, sometimes still need. Getting started for beginners to understand what a hard drive partition formats, this will install the system at the time of the adoption of which format is best suited. Here we talk about some of the hard drive partition formats.

FAT16 format

On the computer for the purposes of the old "bird", on the hard drive partition formats are the most familiar, we mostly through this partition format recognition and into the computer's threshold. It uses 16-bit file allocation table, can support a maximum of 2 GB partitions, is currently the most widely used and the operating system supports a maximum of a disk partition to format, and almost all operating systems support this format, from win3.x, dos, win95, win98 win97 now, windowsnt, win2000, and even popular fad linux both support this partition format.

But the FAT16 partition format has a maximum of shortcomings, and that is the hard drive's actual use efficiency is low. Because in dos and Windows systems, the disk file is assigned to the cluster, a cluster is allocated to a file, regardless of the file using the entire cluster capacity. And each cluster size of the hard disk partition, partition size, the larger the cluster. For example, 1 GB of hard drive if only one zone, then the cluster size is 32kb, that is, even if a file is only 1 byte long storage time should also account for diary of hard disk space, the remaining space is where all the idle, thus causing the disk space of the great waste. FAT16 partitions support a larger disk on each cluster capacity is greater, the waste caused by. So as the current mainstream hard drive capacity increased, this disadvantage is becoming more and more prominent. In order to overcome the weaknesses of FAT16, Microsoft introduced the win97 operating system has a brand new disk partitions formatted FAT32.

FAT32 format

For win98 widely popular today, the majority of computer enthusiasts on this partition format are not unfamiliar. This format uses 32-bit file allocation table, make it to the disk management capabilities greatly enhanced, break the FAT16 partition on each only 2 GB of capacity constraints, use FAT32 partition format, users can define a large hard drive into a partition without is divided into several partitions use, much easier on the hard drive management. Moreover, FAT32 also has one of the greatest advantages: in one of no more than 8 GB partitions, FAT32 partition format each cluster has a fixed capacity of 4, compared with FAT16, can greatly reduce the waste of disk space, increase the efficiency of your hard disk.

Currently, support this partition format of the operating system has win97, win98 and win2000, windowsxp. However, this partition format also has its disadvantages, first use FAT32 formatted disk partitions, because the extended file allocation table, run faster than using FAT16 format partition hard drive slowly; in addition, because some older dos systems and application software does not support this partition format, so this partition format, you can't use the old dos operating system and some older applications.

NTFS format

NTFS partition format is general computer users feel strange, it is a windowsnt network operating system hard drive partition formats, a user must use windowsnt with this partition format. Its significant advantage is the extremely good security and stability, in use are not easy to produce the file fragmentation on the hard disk space utilization and software run faster. It can record the user's actions, through the user permissions for very strict restrictions, so that each user only permission given by the system, the full protection of the network system and data security. However, currently supports this partition format of the operating system is not much, apart from windowsnt, win2000, windowsxp also support this hard drive partition formats.

However and windowsnt, win2000 use NTFS5.0 partition format. New features have NTFS5.0 "disk quotas" in the administrator can limit the disk users can use hard disk space; "encryption" in from the disk read and write to a file, you can automatically encrypt and decrypt the file data. As the popularity of win2000, the majority of computer users will become familiar with this partition format.

Linux partition format

Linux supported file format is very much, but when installed ext2/3 General Select format, swap Exchange area. Ext2 or ext3 file format access is efficient, but is not recognized by windows. Swap is linux's "virtual memory", windows does not recognize, of course, in practice, swap swap area is rarely used.
Through the above description, I think you must be on a hard disk partition common format to understand. Then, quickly according to the operating system installed, you need to partition your hard disk to determine the format.
