Why wipe disk in Windows 7?

It is common that you want to replace your old or small disk with a new or large one. Then how to deal with the replaced disk? Donate it to your friend or sell it to a stranger? In either situation, you need to completely and irrevocably eliminate all data on the disk for privacy & security related data.

Can you simply format the hard drive or delete all partitions on it? The answer is negative. Formatting or deleting operation only makes data invisible to the operating system and the data can be easily recovered by certain recovery software.

In order to keep your important information not exposed to others, you have to take further action like erase or wipe all data from the disk permanently in Windows 7.

It’s wise to take different ways for wiping HDD and SSD

Before learning detailed information about how to perform disk wipe in Windows 7, you could realize the difference between erasing hard disk drive (HDD) and solid-state drive (SSD).

  • HDD applies one or more rapidly rotating platters coated with magnetic material to store data. You can wipe HDD via writing one or zero to the disk to make the data on the HDD non-retrieved.

  • SSD has no movable parts and uses memory chips to store data. If you remove data on SSD like wiping HDD, data on the SSD is actually still there and can be retrieved effortlessly. And there are chances that you will decrease SSD’s lifespan.
