Description

Disk letter binding system and method

The present invention relates to a system and its method, in particular to a drive letter binding system and its method.

Generally speaking, when the hard disk is electrically connected to the host, the operating system of the host recognizes the hard disk and generates a drive letter corresponding to the hard disk. Please refer to the first figure, the first figure is a flow chart showing the operating system identifying the hard disk in the prior art. The recognition method in the prior art includes steps S901 to S903.

Step S901: Electrically connect the hard disk to the host. Step S902: Use the operating system of the host computer to identify the hard disk. Step S903: After the hard disk is identified, use the operating system to generate a corresponding drive letter. When multiple hard disks are electrically connected to the host, the order in which the operating system generates drive letters is based on the order in which the hard disks are recognized, rather than the order in which the hard disks are electrically connected to the host.

Please refer to Table 1 and Table 2 below, wherein Table 1 shows the order in which the hard disks are electrically connected to the host, and Table 2 shows the drive letter generated by the operating system. HDD0 HDD3 HDD6 HDD9 HDD1 HDD4 HDD7 HDD10 HDD2 HDD5 HDD8 HDD11 Table I sda sde sdg SDKs sdc sdf sdh Sdj sdb sdd sdi sdl Table II

The operating system preferentially recognizes the hard disk HDD0 that is electrically connected first, and thus generates the corresponding drive letter sda. Although the hard disk HDD1 is electrically connected to the host computer earlier than the hard disk HDD2, the operating system recognizes the hard disk HDD2 before recognizing the hard disk HDD1. Therefore, the drive letter sdb corresponding to the hard disk HDD2 will be generated first, and then Generate the drive letter sdc corresponding to the hard disk HDD1.

However, in the above situation, the drive letter drift may occur, and there is great uncertainty for the program or application program of the application layer. For example, after the operating system is restarted or the hard disk is electrically connected again, the operating system still recognizes the hard disk HDD0 first, and thus generates the corresponding drive letter sda. Then, the operating system recognizes the hard disk HDD2 after recognizing the hard disk HDD1. Therefore, the operating system first generates the drive letter sdb corresponding to the hard disk HDD1, and then generates the drive letter sdc corresponding to the hard disk HDD2. At this time, the drive letter changes, resulting in the corresponding allocation of this time being different from the hard disk of the previous corresponding allocation, which in turn makes the previously stored files or information invalid. Therefore, there is room for improvement in the prior art.
