I could not understand if the drive is now detected by both PC and laptop but files can not be seen, or still can not be detected. By any means, dropping a laptop could cause some damage, but without professional examination is really hard to tell what is going on. If there are no strange noises from the drive, it may be just the SATA port which was damaged, but that is just an assumption.
My advice: ask assistance from a technician.
Hope that you will find a solution
