A company is retiring old workstations and needs a certificate of destruction for all hard drives. Which of the following would be BEST to perform on the hard drives to ensure the data is unrecoverable? (Choose two.)
Comptia A+ states that there are ways to retrieve data from re-formatted hard drives. degaussing, or complete drive destruction is the only ways to properly dispose of data completely.
I don't think it should be exaggerated here!
It says ["...] ensure the data is unrecoverable." It is not required that the hard disks be destroyed.
It is quite sufficient for a company, and it is not said that it is a large company, to format low-level and then drill through the HDD.
Not even the Department of Defense speaks of burning, but of: Digital media may be destroyed by shredding, melting, and pulverizing. (if already destroy).
So I go with F and B.
The correct answers are drilling and Incineration. The question says the disks are to be destroyed meaning that the disks are not to be reused. Erasing is not for destruction of disk but wiping permanently of data on disk. Erasing can make disk to be reused.
If the hard drives have been burned and are no longer physically available, it is not possible to issue a destruction certificate specific to those particular hard drives. A destruction certificate is typically issued after the hard drives have been properly destroyed and there is no possibility of data recovery. In the scenario you described, where the hard drives have been burned, a destruction certificate cannot be issued for those specific hard drives. However, it is important to ensure that you comply with applicable data privacy policies and regulations and document the proper destruction of the hard drives.
The request is for a certificate of description. This implies a third party. Many of the options can be done in house. But to have proof of destruction would likely be most logical for incineration or drilling. There are mobile incinerator businesses for this purpose too.
B. Drilling: Drilling a hole through the hard drive is an effective way to destroy the platters that store the data. This method ensures that the data is unrecoverable.
C. Erasing: Erasing a hard drive involves overwriting the entire drive with random data. This process ensures that the data is unrecoverable.
E. Incinerating: Incinerating a hard drive is another effective way to ensure that the data is unrecoverable. The intense heat destroys the platters that store the data.
Not sure if the question is implying that there were a large amount of hard drives. If yes, then C may not be the best choice here.
From ChatGPT: "Erasing can be a good option if the company uses specialized software that meets recognized data sanitization standards such as NIST SP 800-88, but this may not be practical for a large number of hard drives."
