Hard Drive problem.. Help!

For anyone who's been inside a 5000..

I accidently gave my unit quite a big knock.

When i boot up.. if i try to access the HD it says "No media present"
If i reboot it loads up fine..

This happens every time.

Obviously the HD is still functioning.. but there is some connection problem.

Perhps i should backup and replace the HD or if its just loose, solve the problem myself..

Anyone with experience have any suggestions as to how to fix my 5000? and what i need to do to open it up and access the HD connection safely?

Cheers..

The sticky at the top of this forum about customizing your MPC 5000, or youtube... search for upgrade hard drive. You aren't upgrading, but shows how to access the hard drive.
