Explanation
A - Lost Clusters. Lost clusters (also called lost allocation units) occur when the operating system marks clusters as 'used' in the File Allocation Table (FAT) or equivalent structure, but no file or directory is actually linked to those clusters. This can happen due to improper shutdowns, software crashes, or file system corruption. They waste storage space and can be recovered using tools like CHKDSK. They are distinguishable from bad clusters (physically damaged) or free/unused clusters.
