A good floppy disk suddenly fails in use, which is zero track damage. There are many ways to rescue data for zero track damaged floppy disks, and there are many introductions on computer newspapers, but the method is too complicated, and the floppy disk that can be rescued is also very limited. In fact, use common shared software HD-COPY to rescue almost all zero track damage floppy disk data, even completely repairing a zero track damaged floppy disk, if you can't save it, maybe there is no other way to rescue.
The first step is to read the data, almost all zero track damage floppy disk can be read with HD-COPY software, but the damaged track has some errors, and the HD-COPY software's configuration file HD-Copy.cfg There are more settings for repeated readouts of bad sectors, that is, the two items of / x and / y are set to / x20 and / y50. After reading the data, they can try to write the data in the buffer to the original. In the floppy disk, if there is no unpackable bad sector error during the writing process, the floppy disk has been repaired, as long as it enters the second step; if the zero track write is unpaid, the floppy is generally Not available,
Another good floppy disk should be selected into the drive; if the zero track is not repaired, it is unpackable, but this disk can only be formatted with HD-COPY. For use, you should also choose a good floppy disk into the drive; then write the data stored in the buffer to the new floppy disk, and then enter the second step.
The second step is to repair the floppy disk with the DOS disk scanner. After the repair is completed, delete the useless file, you can rescue all the data of the floppy disk, and the floppy disk data format that is rescued is the same. I used this method to rescue a lot of floppy disk, I have successful, I haven't failed.
