故障现象一台386兼容机上的40MB硬盘出现读盘错误,经自检后虽然能够通过,但无法自举、完全不能使用。笔者经反复检查,并进行磁盘介质分析,确定为零磁道损坏。该硬盘参数如表1所示。分析与修复根据磁盘介质分析可知,该硬盘只有这一个坏磁道,其他均好,能否可以避开它、另设一个零磁道呢?计算机主板识别不同规格硬盘的依据是存贮在CMOS中的硬盘参数,参数控制磁头找到硬盘的零磁道而进行读 Symptoms A 386-compatible hard drive on the 40MB read disk error occurs, although after the self-test can pass, but can not bootstrap, can not be used at all. The author after repeated inspections, and disk media analysis, identified as zero track damage. The hard disk parameters shown in Table 1. Analysis and repair According to the disk media analysis shows that the hard disk only the bad track, the other are good, can you avoid it, set up a zero track it? Computer motherboards to identify different specifications of the hard disk is stored in the CMOS Hard disk parameters, parameters control head to find the hard disk and read the zero track
