FAQs to Seven Pass Secure Erase
How Long does Seven Pass Secure Erase Take?
The time it takes to perform a seven-pass secure erase is primarily determined by the size of your hard drive. Since the software erases every bit on the drive, the time required for each erase is directly proportional to the size of the hard drive. Usually, it takes several hours to erase seven times. The overall time may also be influenced by the hard drive's speed, the software program you use, and possibly the computer's processor speed.
Can Seven Pass Secure Erase Completely Wipe a Hard Drive Clean?
Usually, seven-pass secure erase can already prevent data from being recovered. Many disk wiping software offers three or five wiping times options, so seven times is enough for many people to wipe the disk clean. If you still want to erase more thoroughly, then you can choose software that offers a higher number of wiping times.
Can I Cancel Seven Pass Secure Erase?
It is better not to cancel seven pass secure erase, because closing the disk wiping software during erasing process, or force it to close will cause data loss. Even if the software has not finished seven pass secure erase, the data on the original disk will be deleted.
