随着多媒体技术的日益普及,CD-ROM 的使用越来越普及,CD-ROM 驱动器已经成为微型计算机系统的基本配置之一,CD-ROM 盘片也成为大多数系统软件。应用软件和MPEG 文件(VCD 文件)的主要载体,采用 CD-ROM 作为软件的载体有许多的优点:容量大、防磁、读写的损耗非常小等,但是 CD-ROM 也有一些缺点。首先就是信息的不可变性,信息一旦写错就没有修改的可能性,所以我们在购买以 CD-ROM 为载体的软件或 VCD小影碟时,就应当首先确保光盘片中的数据没有错误。由于光盘片的容量很大,一般可到650M 左右,常用的工具软件中能测试出 CD-ROM 中每一个文件好坏的不多,手工测试对于成百上千个文件来说,是一件特别縻烦的事,鉴于这种情况,笔者使用 C 语言编制了一个程序,它可以测试出 CD-ROM 盘片中的每一个文件好坏,可以非常方便的测试 CD-ROM盘片的好坏程度。
With the increasing popularity of multimedia technologies, the use of CD-ROMs is gaining in popularity. CD-ROM drives have become one of the basic configurations of microcomputer systems and CD-ROM discs have become the majority of system software. Application software and MPEG files (VCD files), the main carrier, the use of CD-ROM as a software carrier has many advantages: large capacity, anti-magnetic, read and write loss is very small, but the CD-ROM also has some disadvantages. The first is the immutability of information, the error of the information once there is no possibility of modification, so when we purchase CD-ROM-based software or VCD mini-discs, we should first ensure that the data in the disc is not wrong. Due to the large capacity of the disc, usually to about 650M, commonly used tools to test the software CD-ROM in each file is not much good or bad, manual testing for hundreds of files, is a Particularly annoying thing, in view of this situation, I use C language to prepare a program that can test the CD-ROM disk in each file is good or bad, you can easily test the CD-ROM disk is good or bad degree.
