External hard drive can be referred as the hard drive that is portable. They are easy to carry with, easily upgradable and can store data for a long time without requiring any power supply. Therefore, the external hard drives are primarily used for data backup purpose. However, there are certain situations where data from the external hard drive can also be lost. The main reason behind external hard drive data loss is partition corruption.
Consider a practical case, where you got some strange error message while accessing the external hard drive in your computer "The file or directory is corrupted or unreadable". You were shocked to see this message because; you need to access some important data from the external HDD which you have backed up in it for safety purpose. What to do when the external HDD itself is corrupt!!
When such practical inevitable event occurs to you, don’t lose your heart!!! You still have got the chance to recover the inaccessible data from your external HDD. Usually the data in the external hard disk are still there in their original location, even though you cannot access them. The only thing you need is effective software like External Hard Disk Recovery Software to retrieve the inaccessible data from the external hard drive. The software will allow you to retrieve the inaccessible data from the corrupted external hard drive partitions easily. It also helps to recover dead hard drive or external drive data.
However, the causes of partition corruption in external hard drive are explained in details below:
MBR (Master Boot Record) corruption: The MBR is used to start the operating system installed in the external hard disk drive. Therefore, any corruption in the MBR would result in corrupt external hard drive partitions.
Virus attack: There are various types of viruses that can severely affect the partitions in the external hard disk. Using the same external hard drive in different computers can result in virus infection in it. Some viruses can replicate themselves in the external hard drive unless there is a little disk space left resulting in external hard drive corruption.
Power outages: Repeated abrupt shutdowns of the computer due to power outages while the external hard drive is connected to the computer can corrupt its partitions.
Human errors: Certain human errors like accidentally removing important files from the external hard drive can corrupt the partitions in it. Abrupt removal of external hard drive while the file transfer process between the external hard drive and the computer’s hard drive is not completed can also corrupt the file system of the external hard drive hence resulting in partition corruption in the external hard drive.
However, the files inaccessible in the external hard drive can be easily recovered using hard drive recovery software as long as they are not overwritten. If you will keep on saving new data into the external hard drive even after the partitions are corrupted, then the lost files in it may get replaced with the new files. Once the files are overwritten means they are permanently lost. Therefore, keep the external hard drive unused right after data loss.
The hard drive restore utility has powerful built in algorithm that helps you to search and restore data from corrupt external hard drive within few minutes. It can get back data from laptop hard drives even after a partition table corruption that is caused due to interference of recently installed software. The software is specially designed to deal with every sort of data loss scenarios on hard drive whether it is simple deletion case or complex partition corruption case. It can inevitably restore all kind of data from hard drives with bad sectors. The software not only supports all versions of Windows operating system but also supports hard drive recovery on Mac OS X. Data from iomega external hard drives running Mac OS X, 10.5 x and above versions can be retrieved without trouble. It offers demo versions to evaluate its effectiveness as well as the chance of recovery result.
You can successfully execute partition recovery on external hard drive by using the following steps:
Step-1: Download and install the demo version of hard drive recovery software on the hard drive of your computer and connect the external hard drive to it. After launching the software select “Recover Partitions / Drives” from the welcome screen. Then you’ll get a new window with two different options like “Partition Recovery” and “Formatted / Re Formatted Recovery”. Select the 1st option.
Step-2: After that select the external drive as the drive from which the data are to be retrieved and click on “Next”. The data recovery procedure will start as soon as you click on the “Next” option. You can preview all the data restored from the external hard disk after the recovery process completes.
Use a UPS in your computer to avoid corruption due to frequent power failures. Update your computer with latest Antivirus program. Make proper use of the external hard drive and do not remove it abruptly from the computer. Wait until the file transfer completes and then remove the external hard drive using Safely Remove option.
