Reformatting hard drive in Windows 8 erase all data totally?

You may want to remove all data from your hard drive in Windows 8 laptop or desktop out of various reasons like reusing old hard drive, selling outmoded computer and so on. It is well known that you can delete all things or reformat hard drive to make data saved on it disappear. But will deleting or reformatting erase all data totally and irrecoverably?

The answer is negative. Formatting hard drive in Windows 8 just hides data from operating system but not really eliminate data on the hard drive. It is not difficult to retrieve deleted or formatted data as long as you use professional data recovery software. If you don’t want the data to be recovered easily, you need to wipe hard drive.

Two ways to wipe hard drive in Windows 8 easily

Here offer two different ways about erase data completely from disk, pick up one way based on your own situation.

Wipe disk in Windows 8 from Command Prompt

You can wipe hard drive and prevent data being retrieved easily through writing zeros to it from Command Prompt. Here are detailed steps:

1. Click Start, type “cmd”, right click the program and select Run as administrator to get into the Command Prompt.

2. In the pop-up window, input “format f:/fs:NTFS/p:1” and hit Enter to write zeros to every sector of the drive once

Notices:

  • “f” is the drive letter of the partition on the hard drive that you want to wipe, you can change it based on your own situation.

  • A single pass of zeros to a hard drive can prevent all software-based file recovery applications from extracting information from the drive. To be safer, you can replace p:1 with p:2 to do two passes of zeros. If you want to format or wipe the drive that holds running Windows 8, you can insert Windows installation CD/DVD to your computer, enter BIOS to boot machine from the CD/DVD and then go to System Recovery Options window and choose Command Prompt to do steps that mentioned above.

  • These steps are suitable for wiping hard drive in Windows 10/8.1 or Windows 7.

The detailed steps about how to wipe a hard drive has been illustrated in the above content. But if you want to wipe data on a solid sate (SSD) & recover its performance, it is not advised to take the aforementioned way since SSD differs from HDD in structure and formation.

Run it, right click the SSD that you want to wipe data and choose SSD Secure Erase. Then, do as the next prompts to complete this operation.
