Hey there, @Elrobertosuperio!
What is your system configuration and what exactly do you have stored on this drive that you wish to format? If it's just data and software tools, then you could simply use a cloning utility to transfer them to a secondary HDD or better yet, re-install the programs to start from scratch but make sure you backup your personal data somewhere else first, which is what @Hellfire13 most probably meant by copying the files to another drive.
Depending on the games, you might be able to clone them/transfer them to another drive but using a specific tool as copy/paste won't work with an installed software. If you experience any sort of issues with your drive, I'd advise you to run
its brand-specific diagnostic tool or a third-party alternative and determine the health and SMART status of the HDD.
Hope this helps. Keep us posted with the details, though.
