HPFS chỉ hỗ trợ cho WinNT 3.1, 3.5, 3.51 mà thôi, WinNt4.0 ko hỗ trợ HPFS partitions.
mà thôi, tui dịch ra sợ bạn ko hiểu, post nguyên văn tiếng Anh lên nhá:
The HPFS file system was first introduced with OS/2 1.2 to allow for greater access to the larger hard drives that were then appearing on the market. Ad***ionally, it was necessary for a new file system to extend the naming system, organization, and security for the growing demands of the network server market. HPFS maintains the directory organization of FAT, but adds automatic sorting of the directory based on filenames. Filenames are extended to up to 254 double byte characters. HPFS also allows a file to be composed of "data" and special attributes to allow for increased flexibility in terms of supporting other naming conventions and security. In ad***ion, the unit of allocation is changed from clusters to physical sectors (512 bytes), which reduces lost disk space.
Under HPFS, directory entries hold more information than under FAT. As well as the attribute file, this includes information about the modification, creation, and access date and times. Instead of pointing to the first cluster of the file, the directory entries under HPFS point to the FNODE. The FNODE can contain the file's data, or pointers that may point to the file's data or to other structures that will eventually point to the file's data.
HPFS attempts to allocate as much of a file in contiguous sectors as possible. This is done in order to increase speed when doing sequential processing of a file.
HPFS organizes a drive into a series of 8 MB bands, and whenever possible a file is contained within one of these bands. Between each of these bands are 2K allocation bitmaps, which keep track of which sectors within a band have and have not been allocated. Banding increases performance because the drive head does not have to return to the logical top (typically cylinder 0) of the disk, but to the nearest band allocation bitmap to determine where a file is to be stored
Advantages of HPFS
HPFS is best for drives in the 200-400 MB range
Disadvantages of HPFS
Because of the overhead involved in HPFS, it is not a very efficient choice for a volume of under approximately 200 MB. In ad***ion, with volumes larger than about 400 MB, there will be some performance degradation. You cannot set security on HPFS under Windows NT.
HPFS is only supported under Windows NT versions 3.1, 3.5, and 3.51. Windows NT 4.0 cannot access HPFS partitions.
Advantages of NTFS
NTFS is best for use on volumes of about 400 MB or more. This is because performance does not degrade under NTFS, as it does under FAT, with larger volume sizes.
The recoverability designed into NTFS is such that a user should never have to run any sort of disk repair utility on an NTFS partition. For ad***ional advantages of NTFS, see the following
Disadvantages of NTFS
It is not recommended to use NTFS on a volume that is smaller than approximately 400 MB, because of the amount of space overhead involved in NTFS. This space overhead is in the form of NTFS system files that typically use at least 4 MB of drive space on a 100 MB partition.
Currently, there is no file encryption built into NTFS. Therefore, someone can boot under MS-DOS, or another operating system, and use a low-level disk e***ing utility to view data stored on an NTFS volume.
It is not possible to format a floppy disk with the NTFS file system; Windows NT formats all floppy disks with the FAT file system because the overhead involved in NTFS will not fit onto a floppy disk.
