Which term describes leftover storage that exists on a hard disk when a file does not need all space allocated?

Explanation:
Leftover storage on a hard disk when a file doesn't need all space allocated is slack space. When data is stored, the filesystem uses fixed-size blocks called clusters. If a file's size doesn’t perfectly fill the last cluster, the unused portion of that cluster remains as slack space. This space can still hold remnants of data and is a consideration in data recovery and forensics. Sectors are the smaller read/write units, clusters are the allocated blocks, and a platter is the physical disk surface; none of these describe the unused portion within the last allocated block like slack space does.
