故障现象 在DOS提示符下,用DIR命令查看A(或B)驱动器中软盘上的文件目录,结果屏幕提示错误,A(或B)驱动器中读数据错,更换其它软盘后故障依旧。 分析与检修 首先要判断是软故障还是硬故障。把软盘驱动器拆下,换上一正常的软盘驱动器去试。如果机器正常运行,则说明软盘驱动器本身有问题,属于硬故障;如果故障依旧,说明软驱没有问题,可以把软盘驱动卡拆下,用一正常的软盘驱动卡去试,如果故障排除,则是软盘驱动卡的问题,仍属于硬故障;如果故障未排除,说明软驱卡没有问题。 经检查证明,软驱和软驱卡没有故障。这时可用一张好的系统盘插入A驱动器重新冷启动微机,当微机从A盘上冷
Symptom At the DOS prompt, use the DIR command to view the file directory on the floppy diskette in the A (or B) drive. The resulting screen indicates an error, the data read in the A (or B) drive is incorrect, and the fault persists after replacing the other floppy disks. Analysis and Maintenance First of all to determine whether a soft fault or hard fault. Remove the floppy drive, put a normal floppy drive to try. If the normal operation of the machine, then the floppy drive itself has a problem, is a hard fault; if the fault persists, indicating that there is no problem with the floppy drive, you can remove the floppy drive card, with a normal floppy drive card to try, if the troubleshooting is Floppy drive card problems, still belong to the hard fault; if the fault is not ruled out, indicating no problem with the floppy drive card. After checking that the floppy drive and floppy drive card is not faulty. Then a good system disk can be inserted into the A drive to re-start the computer cold, when the computer from the A drive on the cold
