How to Recover Deleted Data from Hard Drives ?

A hard disk is one the most important part of our computer. All important files including users data like photos, videos, documents, Presentation ppt files, Excel files, pdf, folders, emails, programs data, etc are all stored on computer hard drive. If something wrong happens with the hard disk, it becomes a big problem.

In this article, I will be talking about the common cause that affects hard drives and what are the things happens in the background when data are deleted, and I will talk about a Recovery Software solution to recover deleted files from computer hard drive.

How do we often lose our files?

Following are the common reasons which may cause files on computer hard drive been deleted:

1. Computer blue screen or crashed and then can not boot up
2. Accidentally deleted important files from computer hard drive
3. Hard disk is corrupted
4. Accident format computer hard drive
5. Computer resets to factory settings which result in all personal data on computer hard drive been deleted

What happens when files are deleted or computer hard drive is formatted?

The actual file’s data may store anywhere on computer hard drive, and there’s a file table which maintains the address of each file, so when a user needs to read a file, the computer operation system first read the file table to get the address of file’s actual data. Then the actual data is read.

When files are deleted from computer hard drive, the computer operation system actually does not go to erase the actual data. Instead, it only goes to file data and delete the file address entry. By doing this, the space occupied by file’s data is now free as no file in file table is pointing that address, so the address can be used for any new file. Moreover, the delete process will be fast as there’s no need to go to erase the actual data from computer hard disk. Since the file’s actual data is not erased, there’s a chance to recover those data if we can read the hard disk bit and bit and then collect all pieces of data and form them into a file.

Hard drive crash or format will be similar to above, file table could be corrupted which may result in a hard disk crash. When a hard disk is formatted, all file’s data are still there, only all entries in file table are deleted.
