Vehicle Hard Disk Player’s Requirement for the Format of the Disk
At present, Vehicle Hard Disk Player has been an absolute mainstream device among the coach players domestically. However, lots of our clients are still not clear about the formats that the are supported by the Player. Therefore, I hope this passage will be of some help to you.
According to the present operation system, the usual division formats are the following 4 types: FAT16, FAT32, NTFS, and Linux. FAT stands for File Allocation Table. To us, it means the management over the division of the hard disk.
FAT16: DOS, Windows 95 all use FAT16, and Window 98/2000/XP support FAT16 as well. It can manage a division of up high to 2GB, but each division can only has a maximum of 65525 clusters. As the volume of the hard disk or the division increased, the room of each cluster occupied will be larger as well and as a result, lots of room of the disk will be wasted.
FAT32: As the hard disk of large memory emerged, FAT32 became popular since Windows 98. FAT32 is the upgraded version of FAT16, which supports divisions of up high to 2TB(2048G). FAT32 uses less clusters than that of FAT16, thus, more memory is saved.
NTFS: NTFS stands for New Technology File System, is the standard file system of Microsoft Windows NT, and can also be applied in Windows 2000/XP/2003. It differs from the early FAT file system on the fact that NTFS supports metadata, adopts advanced data structure, providing a better performance and a higher stability and utilization ratio. Three versions of NTFS are available: NTFS 1.2 in NT 3.51 and NT 4, NTFS 3.0 in Windows 2000, and NTFS 3.1 in Windows XP. These versions are sometimes referred as 4.0, 5.0 and 5.1. Besides the extra features of the upgraded versions, such as the quotation in Windows 2000, in light of its compatibility, none of Windows 95/98/98SE and ME version is capable of identifying NTFS file system. In addition, NTFS supports file encryption function, offering better security to users.
Linux: Linux is the hottest operation system in 1999, which possesses two disk division formats, different from other operation systems. One is Linux Native, and the other is Linux Swap. These two formats are with high degree of safety and stability, and when combined with Linux, the chance of being down will be smaller. However, Linux is the sole operation system that supports this division format.
According to the video formats it supports, the Player can be divided into two types: Mp4 Player and Mp5 Player. The early Hard Disk Player can even support Mp4.
Since the Hard Disk Player adopts hard disk carrier to store video files, it also has a problem concerning the formats of the hard disk. Usually, the disk on Mp4 Player has to be formatted into FAT32, and Mp5 Hard Disk Player can be formatted either into FAT32 or NTFS to adopts NTSC format.
If we adopts NTSC format, but the hard disk only supports FAT32, the Player won’t be able to find the file. The formatting device attached on the windows operation system is not capable of formatting the hard disk that has a larger memory than 32 GB, into FAT32, and if we try to , the player will not work. In this case, we must use professional formatting soft wares, for example, PQ 8.5.
Currently, Mp5 Player is not constrained by the hard disk format, therefore, we will have more choices.
