Need to wipe a computer hard drive

Many users deleted data or formatted the hard drive before selling or throwing away their computers to prevent the leakage of personal information. However, they may have confused the functions of deleting files, formatting and wiping the hard drive:

What's more, before the deleted files or partitions are overwritten with new data, they can be easily recovered with some recovery software.

● Format hard drive: Formatting a hard drive has the same effect as deleting files, but formatting a hard drive marks the entire drive as free space. The wiped data can also be retrieved by some professional recovery tool.

● Wipe hard drive: Wiping a hard drive refers to completely removing all data, it is the most effective way to ensure the complete destruction of important files including confidential information and any other type of data from the hard drive. It is much safer than deleting data or formatting the hard drive, because the wiped data can never be recovered.
