For many people, floppy disks, which seem to have become outdated, still have some uses for some individuals. Now there are relatively many mobile storage devices, but their universality doesn't seem to reach the level of floppy disk drives. Especially in terms of booting, flash drives or mobile hard drives often have inexplicable problems.

Floppy disks are often criticized for their quality. Indeed, the quality of current disks is hard to say, but proper maintenance by oneself is also very important. If it's not a physical damage, many problems can be fixed by oneself. I used to have several disks that were almost thrown away because they couldn't be read. Once by chance, I found that formatting twice with hd-copy could solve the problem (it doesn't matter much what the capacity is after formatting). After completion, if it can pass the ndd test, there is generally no problem (the floppy disk seems to work better than before after two formattings). But if it's a physical damage, this method can't help (floppy disks should not be placed in a dusty environment or around strong magnetic fields at ordinary times).

If the floppy disk only has the 0 track damaged, the data can be recovered. The method is to combine Hdcopy and NDD, copy the damaged floppy disk to a good floppy disk (Badcopy can also be used). Of course, the 0 track of this "good floppy disk" is still not right for the time being - after it is fixed, use NDD to repair it. Of course, the main file name recovered may be messed up, but the main content is still there.

First, find a good floppy disk, run HD-copy's read, then change to the bad disk, run HD-copy's write. If it still doesn't work, try formatting with HD-copy! The floppy disks repaired by HD-copy have very poor stability. The floppy disks in the past were of very good quality, but now the floppy disks are very bad!!!!!

Formatting once with FDC basically works. For floppy disks that HD-COPY and other software can't repair, after formatting with this software, they are as good as new.
I just came here and don't know how to upload software. You can find this software online. Or find me on QQ: 450645728, and I'll send it to you.

The quality of floppy disks nowadays is really hard to say. If you encounter a motherboard that doesn't support USB boot, it's still safer to burn a CD.

When you fix these disks, your floppy drive is probably going to be messed up.

Forget about fixing the floppy disk

The DEBUG method of xjmxjm1234 is very practical. I have used it before and it is effective

The DEBUG method of xjmxjm1234 is very practical. I have used it, but it didn't work. Formatting once with FDC basically gets it okay. I have used it, but it didn't work

Second, Floppy Disks with Bad Zero Tracks
Cause: Bad zero track.
Symptom: Another friend used a floppy disk to copy and back up files. Due to frequent use of the floppy disk, the zero track of the floppy disk was often damaged. He was reluctant to discard it and had accumulated more than 50 such floppy disks. Although a single floppy disk is not worth much money, if they can be turned from waste into treasure and all repaired for use. Taking these more than 50 floppy disks (the friend has "generously" given all of them to me), I started to perform surgery.

Surgical process: Since it was known that all were damaged in the zero track, first use the old Pctools to see if it works. Run Pctools 9.0, insert the floppy disk, look for it... can't find the floppy disk; switch to Norton 95, finally managed to operate step by step as per its requirements (that's all in English!), and finally it showed that the floppy disk repair was completed. Ha ha, try it, um... still "unable to access A:/, the device is not ready"! Could it really be that these 50 floppy disks are to be sent to the "recycle bin"? In helplessness, I remembered using the HDCopy for Windows software to format it and see, maybe... Follow the 1.44M formatting operation to complete, "?? still the same". Later, I thought why not format it as 1.2M or XXXK, if it succeeds, it's also good. This time I "formatted" it into a 1.2M floppy disk and re-formatted it as 1.44M again. Guess what, it succeeded. The formatted capacity is 1.39M, although it's tens of K less, but it's making use of waste. Moreover, I have a total of 50 such floppy disks?


Hdcopy Click to download] is a very famous small disk tool in the DOS era. HDcopy for windows is its Windows version, which can be conveniently used under Windows. It can complete operations such as copying files and formatting floppy disks. Especially in rescuing data on damaged floppy disks, formatting damaged floppy disks, reading accumulated image files and other aspects, the functions are relatively powerful. Instructions for use: HDcopy for Windows is a green software. Download HB-Hdwin-Ljxz.rar and directly extract it to the target folder, then double-click HB-Hdwin-Ljxz.exe to start

I can't use it
