Those two you have as “HDD” are cd/dvd
The higher one is a standard Korean OEM layout, with the Realtek chip on it giving it away.
The lower one is from a half-height drive. Probably a slot load drive or game machine. Here the cache chip giving it away. Though this one gives me a slight doubt even if it’s a hard drive board it’s missing part of the controller set (meaning a two board setup) and is still cd/dvd class anyway.
The one I was questioning, I believed was a floppy drive with a surface mount motor but couldn’t be sure it wasn’t a minidisc board without seeing the other side. If floppy it’s peripheral class.
