Which action would you take as preventive maintenance for a hard disk in a computer running Windows XP?
1. Low level format
2. Format partitions
3. >>Defragment
4. Change partition sizes
Explanation : You could defragment a hard disk as part of preventive maintenance. A hard disk becomes fragmented over time with files broken into smaller parts and stored in different areas on the hard disk. Performance is degraded because of the need to retrieve all of the parts and reassemble them as a single file. When you defragment a hard disk, you physically move and recombine the file so that it is stored in a contiguous block of disk space, improving performance. This is not always part of preventive maintenance, but it might be appropriate on a very active computer. Disk Cleanup is also sometimes run as part of preventive maintenance as a way of checking for potential disk problems.
You should not run a low-level format as part of preventive maintenance. Low-level format removes all data and disk partitions. This means that all data on the hard disk is lost.
You should not change partition sizes as part of preventive maintenance. Using Windows XP disk utilities to change partition sizes causes all data on the partitions to be lost.
You should not format disk partitions as part of preventive maintenance. When you format a disk partition, all of the data in that partition is lost.
