Question: 1 / 400

The unused space in a disk cluster is referred to as:

A. Unallocated space

B. Slack space

The term that refers specifically to the unused space in a disk cluster is known as slack space. When data is written to a disk, it is stored in clusters, which are the smallest units of storage on a hard drive. Each cluster has a defined size, and when a file does not use all of the space within a cluster, the leftover space is considered slack space. This space can still contain data from previous files, making it potentially valuable in forensic investigations for recovering deleted or remnants of data that were not completely overwritten.

In contrast, unallocated space refers to areas on the disk that are not currently assigned to any cluster and, therefore, do not contain any data. Extended and primary partitions refer to different methods of partitioning a hard drive, affecting how disk space is organized but not relating to the concept of unused space within a cluster.
