Question

you have a set of dvd-rw discs that were used to archive files from your latest project. you need to prevent the sensitive information on the discs from being compromised. which of the following methods should you use to destroy the data? degauss the discs. write junk data on the discs. delete the data on the discs. shred the discs. i want to review this question later. (optional)

Explanation:

• Degaussing only works on magnetic media, not optical DVD-RWs.
• Writing junk data may leave residual data traces that can be recovered.
• Deleting data on optical discs only removes file pointers, not the actual data, which can still be retrieved.
• Shredding the physical discs destroys the optical layer containing the data, making recovery impossible.

Answer:

Shred the discs.
