External Hard Disk Drive Headaches:
External HDDs fail for a variety of reasons just like their installed counterparts. One of the first signs that your external hard drive is failing is sound that it may make. It may sound like an intermittent click but will intensify as the problem worsens. This sound is often likened to metal grinding against metal and can indicate that the read/write heads have been thrown off their axis and have spun out of control. Not only is considerable damage caused to the hardware but it can also cause serious damage to the data. Upon hearing either of these sounds either in their intermittent or continual states you should power down the device and seek professional assistance. We at Cambridge data recovery have 15 years’ worth of experience when it comes to external hard drive failings.
External Hard Drive Mechanics in Disarray:
You might not think when looking at a hard drive that there is much happening at all but the internal machinations of a hard drive move so quickly that it is sometimes almost impossible for the naked eye to see. The average hard drive spins at around 7200RPM so in the space of a year if you use your computer with external hard drive attached it would spin almost 15 million times. Bearing this in mind it is easy to comprehend why a heavy workload might cause the moving components to fail.
External Hard Drive Problems Caused By Power Surge or Outage:
We take for granted the fact that electricity powers our computers and our external hard drives but we tend to forget that the same electricity that makes them work can also bring them to a stand still if too much electricity is introduced into the system. To this end we are often approached by clients new and old to help recover the data from external hard drives that have been rendered useless by a sudden power surge. We recommend to our clients that they utilise a power surge protection unit which will greatly reduce the risk of a surge destroying the circuitry on an external hard drive.
External Hard Drive Firmware Failure & Its Implications:
Firmware is a program used to determine how an external hard drive should operate. But more importantly how it should operate in conjunction with the computer to which it is attached. For a small program such as firmware it has a lot of work to do and carries a lot of weight on its shoulders and if the firmware fails or becomes corrupted – something that can happen if the onboard PCB is damaged – then the external hard drive may cease to function. We at Cambridge data recovery are often called upon by our clients to help recover data that has been left unreadable as a result of a firmware crash.
Operating System Refusing To Recognise a USB attached External Hard Drive:
Have you connected your external hard drive to your computer using the USB port only for it not to be recognised? Is it visible but no data is accessible? Has the computer rebooted when you plugged the USB device in? If any of these have occurred then there could well be an issue with your external hard drive and the result of which may be an inability to gain access to your files if you can see them at all. Operating systems can refuse to acknowledge the existence of USB connected hard drives if there has been a recent change to software or hardware and indeed if there has been a new addition to the hardware configuration. Whilst many would recommend carrying out a system restore this will deal with issues relating to the actual software and any software installations that took place; it will not show any errors to the physical sectors on the disk. With this in mind if your external hard drive has stopped working correctly and is causing the operating system to behave strangely, we recommend powering down the computer and disconnecting the external HDD.
