Explanation
A cluster that is marked as 'used' in the file allocation table but is not actually assigned to any file is referred to as a 'lost cluster' (or lost allocation unit). This condition typically results from improper program termination, power failures, or file system errors. Tools like CHKDSK (Windows) or fsck (Unix/Linux) can detect and recover these lost clusters. They differ from 'bad clusters,' which have physical damage, and 'unallocated clusters,' which are simply free space.
