Single Answer
0Which of the following scenarios is least likely to result in data recovery being possible?
Answer Options
A
A file is deleted from a disk.
B
A file is overwritten by a smaller file.
C
A hard drive is quick-formatted.
D
A disk is degaussed.
Correct Answer: D
Explanation
Degaussing a drive uses strong magnetic fields to wipe it and is the least likely to result in recoverable data. Deleted files can often be recovered because only the file index information will be removed until that space is needed and is overwritten. Quick formats work in a sim- ilar way and will leave remnant data, and files that are overwritten by smaller files will also leave fragments of data that can be recovered and analyzed.
