So my answer is not one drive is reliable enough to "store" your last or lone copy of what you can't lose. All are subject to mistakes, those encrypting malwares or trojans or a drop to the pavement.
You must keep 2 or more copies across the devices you choose.
As to where it goes, it may be on the platters that your drive can't read and drivesavers would put those platters into a good drive for 4 figures of cash. Why do folk take the risk when I can buy a second 2TB drive for under 99 bucks?
I need a hard drive to store mainly special photos and videos but I don't know which hard drive is the most reliable.
Also I don't understand what "backing up" is and how it works, can someone please simply explain it to me? If I were to lose data off my hard drive or if it were to fail, where does my data go? can I ensure it is safe forever as long as I can "back up" ?
Sorry about the newbie questions, just learning still!
