well, if it is the spindle, you can try something anyway cuz its dieing...
get a piece of plexiglass, remove the cover of the hdd and put the hdd in a plastic ziploc bag.
cut a hole into the metal top (there WAS a screw for that center spindle, but not no mooooooooore) and fit a piece of plexiglass into the cutout. Then take some fishtank sealant (NOT SILICONE BASED) and draw a small bead around the plexiglass.
then get some compressed air, blow the hdd out and the cover off, (give the hdd 4 passes) and reattach everything.
if it was the spindle, youll be fine, if it aint, you got a cool display piece lmao Win:Win situation...
