If your drive is making whining and clicking sounds, then you have a mechanically damaged drive which had what we called a 'head crash' due to the drop!
If you can read/access the disk partitions/drives, I strongly suggest that you perform a full disk backup (with track error skipping) to another device. Also try a file by file copy to another drive (slow but you know exactly what is accessible).
You may want to try to use 'Spinrite' (Google and read about it first) to attempt to repair some of the issues but unfortunately, a disk 'head crash' is usually fatal physical condition and data recovery requires specialized equipment and is VERY expensive!
Hope it helps: let me know ho you go!
