[Saving file creating disk error!!!]

Well, I do not want to take a screenshot because in that case, I have to deliberately create a disk error! What is not something that I want to do. If it happens accidentally then that is a different issue.

Initially, I also thought it is the problem of my hard disk. But that is not the case. Hard disk check is done. Health is good. The problem only happens with Paint.Net and it is reproducible. For example, after saving the file, if you close the file and then close Paint.Net, nothing will happen. Things will be fine. However, when the file is open in the Paint.Net and you close the program it will lead to the hard disk error message. So I think it has something to do with Paint.Net. However, Paint.Net does not crash, so I can not submit any crash report.

These are the precise steps that created the problem. It is a very very serious issue! Please do something.

• I had a 27 KB JPG file in the C Drive (Download folder). 
• I use Windows 10 64 bit machine. Latest updates are installed. The machine is up to date.
• I launched Paint.Net 4.1.5 version (latest).
• Clicked the open file button and opened the jpg file.
• Added a dot with shapes tool.
• Clicked the save button. The file got saved. 
• Now the file is still open in Paint.Net. I closed the Paint.Net program.
• Immediately an error messaged popped up from Windows notification centre. Disk Error! Restart Windows to scan and fix the error. I restarted windows and it started checking C drive for error and it took around 15 mins and then the system opened.
