1- I need some ways the company use data on computers before discarding them ?
2- I want three programs that can destroy data on hard disk ?
3- Which method or program is the best for destroying data so that no body can recover it ?
1- When a company wants to discard computers, it is important to ensure that any data stored on those computers is completely wiped out to prevent unauthorized access. Here are some common ways companies use to handle data on computers before discarding them:
a) Data Wiping: This involves using specialized software to overwrite all the data on the computer's hard drive with random information multiple times. This process eradicates the original data and makes it extremely difficult, if not impossible, to recover.
b) Secure Erase: Some computers have built-in functionality, known as "secure erase," which allows for the complete removal of data on the hard drive. This method typically follows the same principle as data wiping, overwriting the entire drive to ensure data cannot be recovered.
c) Physical Destruction: In extreme cases, where data security is of utmost importance or when the computer's hard drive cannot be wiped electronically, physical destruction is used. Techniques such as shredding or drilling holes through the drive can render the data irrecoverable.
2- Here are three commonly used programs for securely destroying data on a hard disk:
a) Darik's Boot and Nuke (DBAN): DBAN is a free data destruction program that can be run from a bootable USB drive or CD. It works by overwriting the entire hard drive with random data multiple times, ensuring the data cannot be recovered.
b) Secure Erase: As mentioned earlier, some computers have built-in functionality for secure erase. This method is often accessible through the computer's BIOS or firmware settings.
c) Eraser: Eraser is a software program that allows you to securely delete specific files, folders, or entire drives. It uses various algorithms to ensure that data is overwritten and cannot be recovered.
3- The question of which method or program is the best for destroying data with no possibility of recovery depends on the level of security required and the resources available. Generally, a combination of data wiping using industry-standard techniques like DBAN or using a secure erase method followed by physical destruction would be the most effective. By employing multiple methods, it significantly reduces the chances of data recovery. It's important to note that there is no foolproof method for completely guaranteeing data destruction, but using reputable methods can provide a high level of confidence that the data has been securely erased.
