Defragmenting and Optimizing a Hard Drive
A hard drive stores data on disks called platters. Each plat-
ter surface is divided into concentric tracks, and each track
is divided into sections called sectors. A group of sectors,
called a cluster, is the smallest unit of data storage space
on a platter.
When data is saved to a new drive, it is written contiguous-
ly, one cluster after another. As old files are erased, clus-
ters that were previously occupied become available for new
data. However, there may not be enough space for the drive
to write a new file in a contiguous set of clusters. The drive
uses the clusters it can, and if more are needed, the drive
uses other clusters in other locations. The result is a frag-
mented file that is scattered in several pieces on the disk.
Over time, as old files are erased and new files are added,
the data on the drive becomes increasingly fragmented. The
more fragmented a disk becomes, the longer it takes to
read and write data because the drive's read/write mecha-
nism spends more time moving back and forth over the plat-
ter searching for fragmented data or free clusters.
Defragmentation software consolidates file fragments that
are scattered on your hard drive into more efficient contigu-
ous clusters. Optimization software reorganizes files so that
the files you use most often can be accessed more quickly.
Quite often, defragging and optimization functions will be
included in one software package, such that both operations
are performed at the same time.
Examining and Repairing a Hard Drive
There are a number of reasons why a hard drive may be-
come damaged or the data may become corrupted. Regular
examination of your disk with a quality disk examination and
repair utility is the best way to prevent disk damage, avoid
data loss, and isolate bad sectors or blocks.
