Introduction
Preventive Maintenance Procedures |

Preventive maintenance
procedures increase the performance of a computer that is affected due to disk fragmentation.
In some operating systems, data files over
a certain size are scattered among various
clusters. Accessing these files is time consuming
because all clusters are searched to put the
files together. Because the data is spread
across the drive, fragmentation occurs. Bad
clusters, on which you cannot perform read/write
operations, also need to be recognized and
marked so that applications do not use them.
All these problems can be prevented by using
software utilities that safeguard the data
stored on your computer. These utilities are:
 |
Disk
Defragmenter |

ScanDisk |
|
CHKDSK |
