I understand and agree with that statement.
But it is also true that anyone that has gotten to this stage has jumped that hurdle many times in the process of storing captured light on their first media, backing that up as they shoot and erasing old backups, sending it to post or to their own post program, and several opportunities to fail in post-production. They should be used to being paranoid with their media.
I – being neither a programmer or an engineer – also always figure that if I can figure it out and follow instructions, then anyone can.
I must say that I have never done a bootable GPARTED, so I can only imagine that there might be some addition confusion to what I see when using a Virtual drive on my computer. But if they are told to do either or both the following commands, wouldn’t it show up well enough? …that if it is a 8 or 32 Gig drive something close to that size will be indicated?
sudo fdisk -l
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
Perhaps every other line should be a warning and urging backups and mentioning that the user is doing a professionals job and they shouldn’t have any distractions at this dangerous point.
