I thought these magnets were neodymium
Usually, as in most, but not all.
Especially as you get back older. Cobalt was popular in 5.25” and 8” drives. And that’s a hell of a magnet! I have to put my foot on the toolbox to pull it loose.

Neodymium is the most common choice in 3.5” drives and many, but not all, smaller drives.
The little drives like old media players were often a magnetic ceramic magnet.

That definitely works well for the larger ones. Sadly I tend to crack the smaller ones this way so I use the heat gun now.
