I am trying to format a floppy disk but always get a "Track 0 bad - disk unusable" error message

Explanation:
You are trying to format a floppy disk and the format fails saying that track 0 is bad on the disk. This occurs even with brand new disks, and even after trying several disks in a new box.
Diagnosis:
The usual cause of this problem is using the wrong type of media. In particular, it is often seen when people try to format a high-density (1.44 MB) disk as a double-density (720 KB) disk, in either a low-density or high-density drive. Many people do not realize that while high-density drives are backward compatible with the double-density format (if you use the correct parameter when formatting), the media is not. High density media have a different formulation and cannot be formatted to 720 KB, even on a high-density drive.
Recommendation:

Use only double-density media if you have a double-density drive, or when you need a 720 KB disk.
If you are using the right media, and you are having problems with one disk, try another one, or another brand.
Make sure the floppy drive types are properly set up in the system BIOS.
If problems persist then you will need to troubleshoot the drive.
