What size Torx driver for the screws attaching platter to motor on WD?

[nine9s]

I am trying to remove platters to destroy them. I took housing cover off, but the Torx screws on the platter are smaller and my Torx driver does not fit.

Anyone know what size those screws (several in middle of platter) are?

Thanks.
