If your hard drive is subject to data loss due to logical failures, like power outages, system crashes or viruses, etc., you will proceed to attempt logical data recovery. In this article, we will reveal the 4 essential steps in this process.
Unlike physical data recovery, logical data recovery doesn’t involve any repairs on physical or mechanical components. It only focuses on logical problems. Issues like viruses, deletion, file system corruption, file structure damage and mistaken drive formatting are most of the instances of logical damage. Generally, in face of such issues, you tend to suffer many troubles, such as failure to boot, unreadable partition, inaccessible files like corrupt PST, unrecognizable external drive and so on. Even though it seems that the case is severe, actually the drive is not damaged physically. Logically failed hard drive is much easier to handle than a physically damaged drive. You can follow the 4 steps below to attempt logical data recovery.
1. Stop Using Hard Drive Right Now
First of all, as soon as you realize logical data loss on your hard drive, you have to stop using the drive. Most of time, as long as the drive is connected to a running PC, the operating system may continue accessing the disk. It means that the drive contains lost data will suffer data overwrite. It is because that operating system is unable to know which section the lost data is actually located on the drive. It only sees the free space for new data.
2. Clone the Hard Drive
If you’ve confirmed that what the hard drive is encountering are definitely logical problems. Then, the next step is to clone this drive. This step is extremely vital as it can separate the original data from test errors or failures in later data recovery.
There is a lot of such software available for cloning drive. You can select the one that is good-quality and reliable.
3. Choose Recovery Software
After that, you’ll be required to select data recovery software. Since logical issues can be fixed simply via software, you needn’t and should never open the drive to examine its internal components. As we all know, with the constant development of data recovery industry, there are too many recovery tools. Some are free, while some are pricey. You had better spend some time carefully selecting a trusty one.
4. Recover Data from the Clone
Eventually, you can utilize the newly cloned hard drive and subject it to the data recovery software. In this process, you should beware of the clone, such as being sure that power supply is stable and consistent. Otherwise, interrupted recovery will surely fail.
