Q

Disk Defragmenter is a software tool used to rearrange data on magnetic drives in order to improve system performance. Defragmentation results in faster read/write operations of a magnetic hard drive’s read/write heads because defragmentation consolidates data into the smallest contiguous regions. This means that the heads can access data sequentially without seeking data fragments in different areas of a disk.

True or False?

A

True

18
Q

An actuator arm assembly failure manifested by loud clicking noise emitted from the inside of the computer case is a problem symptom that should prompt for:
