External Hard Disk Failure

External hard disks are similar to internal hard disks, but the difference is that the external hard disk is portable and is connected to a USB port in order to be read. It also has to be powered directly to the mains so that you can access and save your information. Otherwise, there is no much difference between the internal and portable hard disks. The same things that affect the internal hard drives are the same that affect the external hard drives. So the question one could pose is ‘Is there anything like external hard disk failure?’ and ‘If yes, how does it happen?’
Just as internal hard disks get damaged and fail, external hard disks also do fail. Here’s why:

Power surges: Most computer hardware that is designed to be connected to the power mains have a certain amount of voltage they can handle. This is the same for external hard drives. Thus, if there is a power surge, it means that the external hard drive is bound to get damaged. Supplying more voltage to the hard drive than it can hold can damage the internal components of the drive and cause the external hard disk not to function well. This is a risk as one may lose their data in the process. Therefore, if power goes or if you are not using the external hard drive, remove the power from the mains. It is safer that way.

Human Error: Being portable devices, external hard disks can get damaged very easily, especially because of human error. So far, I have never found a perfect human being. This means that human beings are bound to make mistakes. Man can drop the hard disk and it may get physically damaged. In the worst case, the external hard disk may drop in water, if, may be, it was raining. So, human beings are unpredictable and you cant be sure when the next mistake will be done. It is, therefore, important that you always try and be careful when handling your external hard drive.

Infection by viruses: Just as viruses infect internal hard drives, the external hard drives are no exception. They too can be infected by viruses. The viruses will corrupt the information stored within it and accessing some of the information becomes difficult. In some cases, the viruses make the files inaccessible.
