There are also freeware utilities available on the web that will let you know when your hard drive is about to fail. Use third-party software for hard drive diagnostics if:

You have already run chkdsk, and are still experiencing serious problems that make you suspect disk surface errors or imminent hard drive failure.

You don't know the manufacturer of your hard drive and aren't confident of taking apart your computer to find out.

You've already backed up your hard drive! If you suspect an upcoming hard drive crash or a bad disk surface error, back up your data immediately - don't fiddle round with installing hard drive diagnostic software until you've done this important step.

In fact, if you are aware enough of potential computer problems to run hard drive diagnostic software, you've already won half the battle. Back up your data and replace your hard disk - hard drives are incredibly cheap nowadays. Buying a new drive is much cheaper than trying to recover data from a failed one.
