I have been filling a hard drive and a couple of backup drives with the family pictures and videos. Once a video goes into the archive, it remains there in a folder correctly labeled with the date. The data collection has grown up to the point where I need a new drive (and new backup drives).
But I wonder why should I leave the reserved blank space linux enforces in the drive, which now is above 50 GB I could fill with more videos. It is easy to do that by invoking the 'cp' command as root.
Since I am not going to do anything else with the drive other than archival purposes, I wonder if filling that reserved space would be a bad practice, in this case, and why. I know I shouldn't do that with the main drive inside the laptop, otherwise the system may become unstable, but what about that external drive holding only archival data?
