China DOS Union

This DOS software was released six years ago, only 10KB in size, quite old, but under DOS status it repairs floppy drives better than other software. I once repaired old floppy drives that couldn't be used in my unit, and more than a dozen out of more than 20 were fixed. I also learned this experience from the Internet. Although there are not many uses of floppy drives currently, when you are in a hurry to repair a floppy drive, you can try it. Especially when other software can't repair the floppy drive, you should try it.

The usage method is as follows:

X:\>FMT A: 1440 V （ Press Enter ）

The following content appears:

put desired floppy in drive a: and press any key （ Press Enter ）

Start repairing （ It will take a few minutes ）

HD-COPY also has the function of cleaning the floppy drive heads. I wonder if this FMT is the same?

It turns out it's for repairing floppy disks. I thought it could really repair the floppy drive so magically. For repairing floppy disks, isn't PCTOOLS better?

Thanks for sharing

Hard damage to a floppy disk is impossible to repair; it's either a soft fault or a method of deceiving the operating system.

I have a 1.44M floppy disk. Since it had already been formatted when I bought it, I accidentally used FORMAT under DOS. Suddenly, I remembered that the manufacturer had already formatted it, so I quickly tried to eject it, but it was too late. The floppy drive light was already on, and ejecting it caused damage. When I inserted it again, it wasn't recognized. Using FORMAT prompted that track 0 was damaged. Using PCTOOLS to format didn't work, and formatting it to 720KB single-sided didn't work either. Taking it out and looking at it under a fluorescent lamp, I couldn't see any damage. Maybe it was scratched not obviously, but it was definitely physically damaged. I used NDD to repair it, and it prompted that a low-level format was necessary. Pressing OK prompted to use DISKTOOL, and the repair couldn't be completed. Starting DISKTOOL, I selected the third item to perform track replacement, and the result was successful. It prompted that now NDD could be used to repair. Starting NDD again, I scanned all errors for repair. In the second track, there were 6 consecutive tracks marked as B bad sectors. At this point, this disk was completely working normally and could be formatted under DOS and could be booted as a system disk. This disk could completely be formatted, but be careful not to try to use the /C parameter to re - check the marked bad sectors, otherwise it would destroy the processing information of DISKTOOL, and the track 0 fault would reappear, and you would have to use DISKTOOL again.

Now my computer has even had the floppy drive removed, and I haven't used a floppy disk in two years...

It seems that there should be some effect according to the introduction...
