The data sheet does not say one way or the other. The change to lead free solder was several years ago so most likely the hardware over the last 10 years is all comparatively safe.
Early RoHS solder was not very good leading to hard disk failures back when 500GB and 750GB disks were mainstream. Now 4TB are so low in cost that 8TB are now being mass produced as the next wave of storage. 2TB hard disks are less than shipping costs for most people.
