I have done what i am recommending here, and it worked for me, and others. For a one-shot attempt at getting your data off the drive, you can remove the hard drive and FREEZE it overnight in your freezer. You will also need another hard drive connected to your computer (external drive recommended, or flash drives as large or larger in capacity), to dump the data from the bad drive. Get everything set up BEFORE removing the frozen drive. Remove the bad frozen drive from the freezer, then re-install the frozen drive and try to quickly boot the computer. Don't let it warm up, or the benefits of freezing will be null and void. With some luck, it will boot up and operate, and give you enough time to dump the data onto the external (new) drive. But with the drive making a noise, it may already be beyond hope.
