Why need a hard drive eraser?
Wiping a hard drive is quite different from formatting or deleting hard drive. When you delete or format a disk partition, the inside data seem to be cleared, but actually, they just become invisible to the Windows operating system. With a proper data recovery tool, anyone else can recover the deleted data without effort.
Therefore, before you sell or donate your old hard drive, it is necessary to wipe it completely via a reliable hard drive eraser. That can prevent the next user from restoring your private or personal information. But what's the best hard drive eraser for Windows 10/8/7? Read on and we will tell you what is the best program you can choose.
What's the reliable hard drive eraser?
To be as safe as possible, it is wise to clear the disk in such a way that it’s impossible for anyone to recover the content even with a professional data recovery tool. Here we recommend AOMEI Partition Assistant Professional. It is designed for Windows OSes, such as Windows 10, Windows 7, Windows 8, Windows XP and Vista (both 32-bit and 64-bit). This hard drive erasing software develops “Wipe Hard Drive” function along with 4 different wiping methods for your choice:
▶Fill sector with zero: overwrite the hard drive with zero.
▶Fill sector with random data: overwrite disk with random data.
▶DoD 5220.22-M: 3 passes (pass 1: writes a zero and verifies the write; pass 2: writes a one and verifies the write; pass 3: writes a random character and verifies the write).
▶Gutmann: pass and overwrite hard drive 35 times.
These methods are ranked by the security level and pass times. Now, you can download the Demo version and check out the following guide.
