How to recover data from broken hard disk drive

    A hard drive failure can feel calamitous but it doesn’t have to be. Data on hard drives can be recovered and below we show you how, along with a description of signs that might indicate your drive is stuttering. We also added a bit of info on how to recover deleted files from recycle bins because it’s something we all need, isn’t it?

    Computer hard drives are amazingly clever bits of hardware that provide the foundation for computing. Technically they’re called hard disk drives (HDD) and consist of spinning disks, or platters, that store information in blocks. This information is your photos, music, work documents, email and everything else your store on your computer.

    Hard drives are quite robust too but Please or Register to view links sometimes with serious consequences. Throw your laptop around like it’s a rubber ball and you may well pay the price. Pry open up your drive to have a look inside and very likely it will be destroyed by tiny particles of dust you can’t even see. That said, even when the drive stops functioning the data is usually retrievable unless someone has passed a magnet over the drive, which will destroy the data.

    However, given that your drive will at some point inevitably fail, it pays to back up the drive, to an external device for instance. However, you may only want to protect certain bits of information with a Please or Register to view links which is always a sensible idea and one that will save you a lot of angst given that your files are available anytime and on any computer.

    If your drive does crash it can cost a lot of money to have the data restored. You can restore it yourself but diagnosing and fixing a broken hard drive is a serious business so you need the willingness. But that said, it’s certainly a cheaper alternative than shelling out for what is usually a relatively large amount of money to have the drive restored.

    How to recognize the signs of imminent hard drive failure
    • Strange noises – sometimes you might hear strange grinding noises which might suggest your drive is beyond repair. But that said, the motor might have failed or the bearings that the drive spins on might be grinding. Whatever it is, it’s time to act quickly.
    • Disappearing data – If data disappears or you can’t save documents it may mean that your drive is struggling. There could be other reasons like a virus but these are symptomatic of a failing drive.
    • Computer crashes – if your computer regularly brings up the blue screen of death as it is sometimes known or it crashes during the boot up sequence it could indicate a drive problem
    • Slow access times – modern computers have superfast processors so it shouldn’t take a long time to open up a folder or empty the rubbish bin. If it does, then your drive could well be on the way out.
    The reasons for drive failure
    • Logical failures – this happens when the electronics of the hard drive fail or the software has a problem.
    • Media failures – if the hard drive has been handled roughly, or the magnetic platters are scratched, have read/write errors or low-level formatting problems it can be said to have had a media failure
    • Head failures – this happens when the read/write head crashes into the drive platters
    • Mechanical failures – these are the most common types of drive failures and happen the motor burns out, the drive overheats or the bearings get stuck.
    How to recover failed drives
    Is it the drive or something else? Sometimes, a drive failure isn’t a drive failure it can be the cables that connect the drive with the computer’s motherboard that have come loose. Make sure the data and power cables are firmly connected on both ends.

    Printed circuit boards? Sometimes hardware connected to the drive can fail such as the printed circuit board (PCB). In theory you can simply swap the PCB boards but if you’re unsure you might want to get an expert to do it – if you don’t know what you are doing you could inadvertently wipe all the data on the drive.

    Take the drive out and connect to another computer – and then copy the data. If you’re certain that the drive has crashed you can remove it from the computer and connect it to another computer as a secondary drive. You can do this using a Please or Register to view links

    If you can browse the contents of the drive it probably means that the operating system has been corrupted and the data on the drive is fine. If so you can try and copy the data from the failed drive to the drive on the computer you’re connected to.

    Data recovery software. If you can’t manually copy the user data off the drive then you can try to recover it using data recovery software. There are many recovery software versions available but don’t install the software on to the drive that you are trying to recover data from. You could end up overwriting files that you want to restore.

    If you’re not technically minded it might seem a little daunting to use recovery software. But if you can find your way around a computer, the instructions that come with recovery software will be straightforward.

    The software below is just a small sample of what is available:

    • Please or Register to view links is a free hard drive recovery tool from Piriform. If the basic scan fails, there is also a deep scan to discover more deeply-buried results.
    • Please or Register to view links provides a demo version that allows you to see what files it can recover. If you like what you see you can purchase the full version.
    • Please or Register to view links has been around a relatively long time and is widely regarded as good recovery tool. It’s available in different languages. It also allows you to restore files that have been permanently deleted from the drive as long as they have not been overwritten.
    • Please or Register to view links reconstructs lost files, regardless of whether they were deleted accidentally or are inaccessible due to a crashed hard drive, hardware failure or virus infection.
    • Please or Register to view links is a free version of a commercial product. It is simple to use: point it at a drive, it’ll scan for deleted files, then you can view particular file types by choosing them from a tree.
    • Please or Register to view links is probably one of the simplest data recovery tools available. There are no complicated options or dialog boxes all you do is choose a drive, click Scan, and wait as the program locates any deleted files.
    A warning

    Hard drives are sensitive bits of hardware and can easily be damaged if you pull them out of their casing. If you’re not sure or feeling confident it’s probably a good idea to go down to your local computer shop or contact a data recovery specialist.

    And finally – recovering deleted data from Recycle bins

    While we’re on the subject of recovering data from hard drives its worth mentioning that it’s also possible to recover data from Recycle bins. We’ve probably all dumped files in the recycle bin, emptied it and then a later date wish we hadn’t.

    Many of the publishers of tools mentioned above provide recycle bin recovery software too. There’s a Please or Register to view links from Please or Register to view links that provides a list of software with some simple step-by-step guidelines

    How to recovery data when the harddisk no detected Boss? Any hardware to solve this problem?
