It's such a pain to recover the lost data from an HDD. Been there, done that lol. To be clear, you physically dropped the drive and caused physical damage, which made it stop working. Suppose your data is of any value to you. In that case, you should first seek professional data recovery services from a lab that will start by physically assessing the heads and platters before powering them on. If your data isn't worth the low-end rates of a few hundred bucks, then it is worth moving forward with DIY attempts, understanding that the drive may completely crash before you get a single file recovered.
