What is Cluster?
| Disk Drive Data Clusters |
|
A sector is the smallest accessible division of a disk. These are created during a low-level format, which is usually only done at the time of manufacturing. Sectors are like the parking spaces in a parking lot. A cluster is a group of sectors. Your files are actually stored on the disk by the Operating System writing to clusters. We'll talk a lot about this later on. A clusters similar to a group of parking spaces within a row, where these groups are separated by the lanes you drive up and down in. Tracks are concentric rings on the surface of the disk. Within tracks reside sectors. Tracks are like the rows of parking spaces in a parking lot. Lost Cluster A lost cluster is a cluster that the operating system has classed as being in use, but actually contains no data. The ScanDisk utility within Windows is designed to search for lost clusters and make them available to the file system again. |
