Not a good link to give! The very first words of advice in that link are "You need to format the drive".
If this guy is new, he might do it.
► Replace the SATA data cable (or swap with another drive). Yes, they do magically go bad. I've seen it twice.
► Go into BIOS setup and see if it can see the drive. That's a major decision point for solution advice.
► Even if the BIOS doesn't see it, you can very likely read it with a USB external HDD connector (like, 20 bux). It uses an entirely separate execution path to access the drive.
Yes, yes, I know: when I first saw that in a Chinese guy's YouTube vid, I said, "Aww, bulls hit\." too. But while I was away for a month, one of the guys in this group house screwed with my PC, dropped it, and killed the data and backup drives. One of them was dead and the other spun up, but was invisible. I needed to pull data off it to a replacement drive and to my amazement, it worked. Use USB3.
► Pick up the running drive and see if you feel gyroscopic resistance when you rotate it. If not, the drive is dead. However:
► Another solution that has worked for me involves the fact that for 2/3 of unreadable drives, the fault is the electronics on the controller card (which is screwed to the bottom of the drive). The odds improve greatly if the drive spins up (without going "click-click-click"). You can get used controller PCBs on eBay.
In a repair shop I worked at, we had a HUGE pile of bad drives. I raised many of them from the dead like they were TWD walkers by merely swapping controller boards with an identical drive. We sold them as used. The disreputable owner also put them in new system builds. He did a lot worse stuff too, like sell fake cache chips.
BTW, never give a drive with porn on it to a repair shop unless you want to be embarrassed. The guys invariably did a DIR /s *.jpg from root to find stuff to add to their own collection.
