Your saviour from Australia is here.
A little education first.
When the hard drive tends to spin still when plugged in, physical components are generally ok. What happens when the hard drive falls is that a small needle that reads and weites over electric impulses imbeds data (binary
Code) 0 and 1. What generally happens when the magnetic disk in side the chassis receives a strong g force shock is the data at the start of the disk (section 1) and the end sector 4927261820382) whatever the size of the disk e.g 500gb is corrupted. This is just generally speaking. It all depends on where the needle is when it's writing or whether it's just reading and other complicated scenarios.
So if It still boots up without any detection for either O/S or bios (doesn't matter) it's probably the boot sector and/or MFT that's corrupted.
All you need is a program called GetDataBack. It doesn't read the drive as a file system format, it just reads it as a physical drive and reads all sectors. From there you can recover all the data, transfer it onto another drive or your desktop(whatever your desire). After that reformat the drive. Test reading and writing data on it. There's to much to write on here. Pm me of you needier help
