笔者得到一个拷贝有应用程序的5″磁盘,放入使用正常的5″软驱后,能读出磁盘目录,也能正常进行整盘拷贝,但试图将文件拷入硬盘时却出现:Sector notfound(扇区不存在)的出错提示.经反复试用COPY、XCOPY及PCTOOOLS中的文件拷贝都不能正常读出,但用PCTOOLS的磁盘检验功能检查磁盘时却报告磁盘完好(OK!).致使有一段时间无法使用这盘软件.后来,笔者了解到这盘软件是用HD—COPY从3″盘拷到5″盘的,经过反复研究才找到解决办法.原来,HD—COPY把3″盘(1.44MB)拷到5″盘(1.2MB)时是按照原来3″盘的格式(即80磁道18扇区)来拷贝的,而5″盘的正常格式应是80磁道15扇区,所以这样拷贝出来的5″盘不是标准格式.因为拷贝盘仍是80磁道,所以用DISKCOPY(按磁道拷贝)仍能正常进行,但拷贝文件时要读扇区,拷贝盘每磁道扇区数与标准不同,难怪要出错了.
I get a copy of the application of the 5 “disk into the normal use of 5” floppy drive, can read out the disk directory, but also normal whole disk copy, but try to copy the file appears on the hard disk: Sector notfound ( Sector does not exist.) After repeated trial COPY, XCOPY and PCTOOOLS copy of the file can not be read normally, but with the PCTOOLS disk test function to check the disk when the disk is reported intact (OK!), Resulting in a period of time Later, I learned that this disk is HD-COPY from 3 “disk copy to 5” disk, after repeated research to find a solution. It turned out that HD-COPY the 3 “disk (1.44MB ) Copied to a 5 ”disc (1.2MB) is copied in the same format as the original 3“ disc (ie 80 tracks of 18 sectors), while the normal format of a 5 ”disc should be 80 tracks of 15 sectors, so this is copied 5 "disc is not a standard format.Because the copy disc is still 80 tracks, so DISKCOPY (by track copy) can still be normal, but copy the file to read the sector, copy the number of sectors per track and the standard is different, no wonder To be wrong.
