Hello, sad to hear about your hard drive issue.
There is a possibility that you can still retrieve some data from your hard drive. If this works, try obtaining the most you can and don't shut down or restart the computer until all data has been removed.
You can connect the hard drive as a SLAVE drive (SATA 1) on a computer with a MASTER hard drive (SATA 0) that holds the bootable OS.
Hopefully, you will be able to access the hard drive through the MY COMPUTER directory.
If attempt number one fails, try putting your ailing hard drive in a freezer for a night and on the next day, attached it as a SLAVE drive (SATA 1) and hopefully, the drive will allow you access to your data.
If this fails, your only course of action is either send the drive out and have it professionally done or you if have a spear SATA drive handy with the same controller board, you could switch platters from one drive to the other, however, I must warn you, dust will with no doubt, get into your undamaged drive and could cause damage to the platters of the working drive. Do this ONLY if you wish to take that risk.
