NTFS file system wonderful seven questions and seven answers

        1. What is ntfs?

want to know ntfs, we should first know about fat. Fat (file allocation table) means "file allocation table". For us, its significance lies in the management of hard disk partitions. Fat16, fat32, and ntfs are the three most common file systems.

fat16: We used to use DOS, windows 95 uses fat16 file system, now commonly used in Windows 98/2000 /xp and other systems support fat16 file system. It can manage partitions as large as 2gb, but each partition can only have a maximum of 685525 clusters (the cluster is the configuration unit of disk space). As the capacity of the hard disk or partition increases, the space occupied by each cluster will become larger and larger, resulting in waste of hard disk space.

fat32: With the advent of large-capacity hard drive, beginning from Windows 98, fat32 became popular. It is an enhanced version of fat16 that can support partitions as large as 2tb (2048gb). The fat32 uses a smaller cluster than the fat16, which effectively saves hard disk space.

ntfs: Microsoft "target="_blank" class=blue> Microsoft Windows nt kernel series operating system supports a disk format specially designed for management security features such as network and disk quotas, file encryption, etc. With the popularity of Windows 2000/xp with nt as the kernel, many individual users have started to use ntfs. ntfs also stores data files in clusters, but the size of clusters in ntfs does not depend on the size of the disk or partition. The reduction not only reduces the waste of disk space, but also reduces the possibility of disk fragmentation. ntfs supports file encryption management function, which can be used to smash V?

2. What? The system can support the ntfs file system?

Only windows nt/2000/xp can recognize the ntfs system, Windows9x/me and DOS and other operating systems can not support and recognize the ntfs format disk. Because the dos system does not support the ntfs system. , so it is best not to make the c: disk as ntfs system, so that it is easy to repair under DOS system after the system crashes.

ntfs and operating system support table

Operating system supported by the file system

fat16 Windows 95/98/me/nt/2000/xp unix, Linux, DOS

fat32 Windows 95/98/me/2000/xp

ntfs Windows nt/2000/xp

3. Do I need ntfs?

Windows 2000/xp is backward compatible on the file system, it is well supported. Fat16/fat32 and ntfs, where ntfs is a Windows NT/2000/xp-specific format that makes more efficient use of disk space, supports file-level compression, and provides better file security. If you only install Windows 2000/xp, It is recommended to select the ntfs file system. If the system is multi-boot, the system disk (c drive) must be fat16 or fat32, otherwise multiple boot is not supported. Of course, the file system of other partitions can be ntfs.

4. How to Convert the fat partition to ntfs?

windows 2000/xp provides the partition format conversion tool "convert.exe". convert.exe is a DOS command line program included with Windows 2000, which can be directly used by this tool. Convert fat to n under the premise of destroying the fat file system Tfs. Its usage is very simple. First switch to the DOS command line window in Windows 2000 environment. At the prompt, type:

d:\\>convert drive letter to be converted /fs:ntfs
< BR> If the system e disk is originally fat16/32, now you need to convert to ntfs, you can use the following format:

d:\\>convert e: /fs:ntfs

All conversions Will be completed after the system is restarted.

In addition, you can use special conversion tools, such as the famous hard disk partitioning tool non-destructive partition magic, use it to complete the conversion disk file format is also very easy. First select the partition to be converted in the disk partition list in the interface. Select the "convert partition" button from the interface button bar, or select the "convert" command from the "Operations" drop-down menu in the interface menu bar. Activate this function interface. In the interface, select the conversion output as "ntfs", then click the "ok" button to return to the main interface of the program. Click "apply" in the lower right corner of the interface to add settings. After that, the system will reboot and complete the conversion of the partition format.

5, although the ntfs format partition is superior, but how to recover lost files in this partition?

You can use specialized software such as final data for ntfs, or get data back for ntfs. The download sites for these two softwares are www.freedownloadscenter.com/utilities/disk_main-tenance_and_repair_utilitIEs/getdataback_for_ntfs.Html and http://www.finaldata.com/
. The file recovery of these two softwares is good. If there is no file operation after the file is deleted, the recovery rate is close to 100%. So don't wait until the file is deleted before installing the software. It is best to install it with the Windows system and perform the recovery operation immediately after the file is deleted. Generally, the deleted file can be restored.

6, my Windows 2000 /xp installed in c drive (ntfs format), if you can not enter the c disk in DOS, when Windows crashes how to do?

you can use windows 2000 /xp installation disc to start to repair the windows, or the fabrication and installation of an emergency boot disk windows 2000 /xp's. Note: Windows 2000 installation disk creation program is on the installation CD of the program, and Windows XP emergency disk production is provided separately and needs to be downloaded from Microsoft's website (in "China Computer Education News", No. 5, 2005, 35th Edition There is a related introduction in the worry-free question and answer column).

7, final data for ntfs or get data back for ntfs may be accidentally formatted hard disk repair it?

Yes. Both software can recover formatted deleted data (except for low-level formatting). The conventional format deletes only the data information, and the low-level format deletes all the data areas. When the hard disk technology
is not as developed as it is now, the disk surface is easily worn out. Hard disk users often use low-level formatting for frequently occurring read errors. To repair a formatted hard drive, you can only remove the hard drive, install it on another computer, and then perform a file repair operation. Final

data can even repair hard drives destroyed by chil virus.
