You can easily check it. Measure the resistance between all 4 leads from the head. They all need to be in the 2 digit Ohm range. If any of them is different (usually infinite = open), the R/W head is dead. > Is there anything to do to the mech?

Even if you had a spare head, you'd have to align it after replacing it, otherwise it will only read it's own disks. I consider a dead R/W head final and use the whole drive for spare parts.
