Possible hard drive failure...advice needed!!

My computer crashed the other day, and now it no longer boots up.

I was in the middle of a game when I heard the hard drive click and then the computer reset. After that whenever I try to boot up, the hard drive begins to click and the process stops there. The BIOS appears in order, the memory test is okay, and the boot up screen appears to recognise the boot partition of my hd

I've tried using a boot disk, but still run into the clicking, though it does works when I disconnect the hd.

My system is only 2 years old, and this is the first time I've had any major problems with it. I'm thinking its a physical failure of the hard drive, and if that's the case, is there any way to retrieve my data?

I'd greatly appreciate any insight or advice people provide.
Thanks,

Depends on whether it's a freeze-up or not....but it doesn't sound like it. If it's critical data that you are willing to pay for, there are companies that charge an arm and a leg but most likely will get your data.
If you have another comp or a friend with one and it is stiction (plates freezing together) place the drive in a freezer for an hour. Remove it, connect it as a slave to another hard drive in a system and you might be able to "see" it from the system to retrieve your data. I've had this work twice for me.
Please be careful if you try this. Cold to heat (and vice--versa) causes condensation. You're working with electronics so keep the slave drive separate from the rest of it.

Good luck!

If it's stiction, and the above doesn't work, one last thing to try is this. Take your drive, and with it's bottom surface, bang it against6 a table top or something similar. this may unstick the drive. Don't go OTT with it. Just a firm whack.
