Not familiar with software to recover corrupted or lost files, take a look at this site, good brand software and free, can try it. From looking at diskpart and disk management showing drive it empty, probably from damage of being dropped.
If can not access the drive going to be hard to transfer the contents and possibly recover from.
Not all do this, but when i setup my PC inside it i have one HD drive designated for Data only and then i also have an additional USB HDD for that same data backed up again.
So if one fails, always good have more then one backup i learned. Use a thumb drive to do this as second backup in future.
