What should you do first if a user cannot save a file to a floppy disk?

When a user is unable to save a file to a floppy disk, the first step should be to verify that the disk has been inserted correctly and is properly formatted. This step is crucial because if the disk is not formatted, the operating system cannot write data to it. Additionally, improperly inserted disks might not make proper contact with the drive, leading to read/write failures.

Starting with this step allows you to rule out basic issues that can easily be resolved. If the disk is not correctly inserted or is corrupted due to improper formatting, addressing this will often solve the problem without needing to explore more complex solutions, such as updating software or replacing hardware. Therefore, verifying the disk ensures that you are working with a functional medium before considering other potential issues.
