Data Recovery after Disk Defragmentation

The operating system stores a file on hard drive on multiple locations by dividing it into several parts. It causes a file to become fragmented. It decreases the accessing speed of your computer as sequential reading or writing of data on the fragmented hard drive is slowed down because the time required for the drive head to go between fragments and waiting for the drive platter to spin into positions is increased.

To fix this problem, you need to “Defragment” your hard drive. Defragmenting is a process to arrange all the files in as much contiguous space as possible. You can perform this task with the help of inbuilt windows utility “Disk Defragmenter”.

Disk Defragmenter examines local drives and consolidates the fragmented files so that every file can occupy a single and contiguous space on the drive. It allows programs and data to run more quickly and efficiently because the OS doesn’t have to read or write files from or to multiple locations.

Though, disk defragmenting increase the accessing speed of your computer, but it’s not always beneficial. Sometimes it may create serious problems especially in case when you use disk defragmenting after data loss.

What happens when you use disk defragmenting after data loss?

In case when you have deleted a file accidentally or formatted your hard drive and you run disk defragmenting, the defragmenting shift the files on the cluster from which you have deleted file. In the process of defragmenting, the Defragmenter rearrange the clusters, in these situations, the path of your files may get changed.
When the path is changed, the general data recovery software can’t recognize or locate the lost data and may fail to recover your data. In these circumstances, you need for good data recovery software like Stellar Phoenix Windows Data Recovery software. It might possible that disk defragmenting may overwrite the data, in these cases, software solutions for data recovery becomes very difficult or sometimes may be impossible.
