How do we solve fatal errors on a PC hard disk?

I face a lot of fatal errors on so many hard disks. On many of these errors, I receive the error message that the hard disk will be damaged unless I change the drive. What are the various ways to solve a fatal error on a PC hard disk?

    Yeah there are many ways to solve a fatal error on a PC hard disk. But best way is to replace it.
    Make hdd backup while you still got time else you will find one more thing to regret.

    Oron J discussed power problems. To ensure what he advises, protect your computer and peripherals with a good battery backup.

    There's only one tool for "reconditioning" failing hard drives, and that's Spinrite. However, you shouldn't expect too much from it, and you shouldn't rely on it either. SpinRite was written in an age when hard drive technology was quite different, and although it has been updated to run on the latest systems and with the latest drives, its eficacy is doubtful on modern drives.

    The message you mention sounds like S.M.A.R.T messages. They are generated by firmware built into the hard drives themselves, and use algorithms to predict when the drive is going to fail. They may be wrong, of course, but the algorithms are based on observing actual performance data, so they should be taken seriously. Spinrite can only reposition data on the discs and mark sectors as good or bad. It cannot actually undo hardware failure (despite confusing claims on the website).

    If I were you I would concentrate my efforts on finding out why you are seeing so many failing hard drives. The chief causes are:
    Age or "flight hours". Hard drives fail at an average rate of about 3-5% per year. Over time, the rate of failure will increase. There's nothing you can do about that.
    Rough handling. Although modern drives are much better at coping with knocks and falls, they are still ultra delicate devices and even if they don't fail outright, a knock could push the heads slightly out of alignment or damage some sectors. Over time this will accumulate to major damage. Try to protect your drives from mechanical jolts of any sort.
    Power problems. Again, although hard drives can cope with the ocasional power failure, power spikes, "brownouts" or poor power regulation will take its toll on hard drives and will either damage them instantly or over time. Do your best to ensure your drives get a steady and well-regulated stream of electrons!

    Finally, some drives are (a little) better than others. Certain drive models, on the other hand, have had design or manufacturing faults and developed problems over time. Fujitsu in fact pulled out of the 3.5" market a number of years ago when a major firmware fault caused it to lose a huge amount of money in repairs and lawsuits. All other manufacturers have had similar problems too, albeit on a smaller scale. Look to see if your particular drives are known to be prone to failure.
