To speed up your hard drive this process reduces unused disk sectors.

• A. Defragment
• B. Reformat
• C. Encrypt
• D. Compress

Answer: (A)

Defragmentation reorganizes data so that the parts of files sit in adjacent sectors. When a drive’s files are fragmented, the read/write head must move to many different locations to assemble a single file, which slows everything down. By pulling the pieces of each file together and grouping free space into larger, consecutive blocks, defragmentation reduces the head’s roaming and makes reads and writes faster. The other options don’t improve layout in that way: reformat wipes and rebuilds the drive, encryption adds security overhead, and compression saves space but doesn’t fix how data is laid out or speed up access.
