How do I repair an unreadable Hard Drive?

I currently have a 2TB Hitachi 3.5" Hard Drive I purchased new 3 years ago but was saving until I ran out of storage on my other Hard Drives, That time came. So the other day I put the drive in my spare external enclosure and it was unreadable, all it did was make unusual clicking noises constantly. Is there a way to fix it?

    if it's broken, you need to buy a new one.

    recovering files is not a simple thing if the drive is broken. if it's NOT broken, files are still kind of tricky to recover. unreadable is unreadable.

    You don’t - if the data is precious and you need it recovering, you can send the drive to data recovery specialists where they can rebuild the drive and recover what they can. They aren’t cheap however.

    The clicking means it's getting power and is trying to run but can't do so. Doubtless, as other have said, the lubrication for its bearings has dried and solidified so it can't move properly. The only answer is to get a new one, unless you have a watchmaker's skills and abilities.

    Drive is dead, sorry. buy a new one is your only option.

    Hard drives, if not used for a long period of time (years) the oil, which is used as the bearings for the drive. Its highly likely the bearing have died in the drive.

    use your drives at least one time per year to keep this from happening.

    As others have stated, the drive appears to be experiencing what is called the “Click of Death.” Whenever you buy new equipment you should always test it to make sure it tests usable because you don’t want to end up opening something later on that turns out to be faulty and it is so long past the purchase date that there is probably no warranty. Just to make sure you should take the serial number of the drive to the manufacturers website where you can check the warranty on this drive before you throw it away.

    Sorry no, it's dead. That is called the Click of Death.

    A clicking noise means there's either a mechanical problem, or it's not getting enough power. If it's a mechanical problem, then it's not economically worthwhile to fix it. If it's a power issue, you'll need to find an enclosure or power supply that delivers more juice.

    Build a clean room (big enough for you and a desktop, light, and air filters).  Get a "bunny suit" to make sure you don't spread any dust particles.  Breath through a face filter.  Get a magnifying glasses set.  Get gloves, and a small tool set for taking apart the drive.

    Buy an identical model drive.  Put it and the problem drive on desktop, let air filter out for a long while while you wipe down everything with a dustless cloth and alcohol and deionized water or distilled water.  Open both drive cases.  Gently remove the platter and spindles and swap over the data containing one into the new case.  Seal it up carefully.

    Now exit clean room and try the repaired drive.  If same result, throw it away.
