Try putting the drive in the freezer for half an hour,
THIS IS NOT A JOKE, (remove the battery first). Put it in a loose fitting polythene bag but don't seal it, while it's in there set up your download cable to your PC and have everything ready for a quick download, make sure your drive battery is fully charged ! After about half an hour, remove the drive from the freezer, quickly refit the fully charged battery, plug in your download cable, switch on the drive and attempt to download your files to your PC as normal. You may need to go through this procedure several times before you retrieve all the files that are available, you may not recover them all. This is usually a last ditch attempt at file recovery from a drive that's mechanically knackered. If this works, dump the faulty drive and replace it with a new laptop drive. I've managed this procedure a few times for desperate clients, works sometimes, depends on how badly damaged the drive is.
Don't dump the drive just yet, there may be other work rounds you can try. It may be that your hard drive head crash has just corupted some of the sectors on the drive platters, if this has not caused any serious mechanical damage it can be possible to recover some or all of the sectors using a small piece of software called HDD Regenerator v1.51, you can download a trial version of this at the following web link.

I've used this software many times, it can be a life saver for what seemed to be an unrecoverable hard drive, it does work!
Good luck.
