What is the primary role of the logical block in HFS file systems?

In the context of HFS (Hierarchical File System), the logical block plays a crucial role in tracking the allocation status of files on the disk. Each logical block is responsible for managing the allocation and deallocation of storage space for files within the file system. This means that when a file is created, modified, or deleted, the logical block keeps a record of which areas of the disk are being utilized and which are free, ensuring efficient use of available storage.

The ability to track allocation status is essential for the file system to manage space effectively and prevent fragmentation, which can adversely affect performance. By knowing which blocks are occupied and which are available, the file system can allocate new files or extend existing files without overwriting other data.

Other options such as storing file paths, maintaining user permissions, and logging system changes are not the primary functions associated with logical blocks in the HFS. While file paths are managed through the directory structure and user permissions are typically handled by the file system metadata, these are separate concerns not directly associated with the allocation status that logical blocks manage.
