Can't read older drives?

[Mangudai]

I have some hard drives from 3-5 years ago that have been sitting around. I tried to add then as slaves to see what was on them which worked with one but with the other two or three it said the drive needed to be formatted? Why is this?

jumper setting perhaps?

Did they sound like they spun up correctly and are not making clicking sounds?
