For questions regarding file formats, or formatting hard drives.
We can ask questions about file formats or formatting hard drives under format tag.
Instead of this, why can't we have a separate tag for file formats and a separate tag for formatting hard drives?
I just now got to know that there is already a tag named file-format.
This makes me feel that the format tag is vague.
In my opinion, the best thing to do right now is to get rid of format tag and, as Zanna suggested in her answer, create a new tag named disk-formatting for questions related to formatting storage devices. The scope of file-format is a matter which needs to be addressed some time later.
