Disk driver cluster management of time shift buffer with file allocation table structure
First Claim
1. A computer readable medium having a file allocation table encoded thereon, said table comprising:
- a first data structure comprising file list entries for files, wherein the file list entries include clusters allocated for each of the files; and
a second data structure comprising cluster list entries for the clusters, wherein the cluster list entries identify the clusters and a quantity of the files that simultaneously share each one of the clusters, wherein a quantity value is at least two, and wherein a quantity value greater than one indicates that the cluster not be deleted.

Abstract
A file allocation system for a hard disk drive includes a memory with driver logic and a processor configured with the driver logic to receive a request to allocate hard disk space of a defined size for a buffer file. In some embodiments, the processor is configured with the driver logic to allocate clusters for the buffer file from a plurality of clusters on the hard disk, wherein the clusters for the buffer file store media content instances. In some embodiments, the processor is configured with the driver logic to designate a portion of the clusters of the buffer file for at least one non-buffer file such that the non-buffer file is permitted to share the portion of the clusters of the buffer file with the buffer file.
