Hard disk is the basic of the a computer system. It is where all the information are written into and read from. If a hard disk is corrupted or injured, the stored information may be lost; more over, the system, which is counted on reading data from hard disk, may crash completely. You may totally lose this computer. The common disk errors are:
"Fatal Error - Cannot access hard disk""Hard disk drive failure""No fixed disk present""bad track""strange sounds when reading hard disk"
The reasons of such errors are complicated. Apart from the regular ageing of hard disk, it may also be caused by hear, low memory or too much dust. To keep the hard disk healthy, we wil need to clean and defrag hard disk regularly. In windows system, two tools are already equipped to help us. They are:
Disk Cleanup tool
Using this tool you can empty your Recycle Bin and remove the following items from your system
- Temporary Internet Files
- Downloaded Program Files, such as downloaded ActiveX Controls and Java Applets
- Temporary Windows Files
- Unwanted Windows Components
- Unwanted Installed Programs
To start the Disk Cleanup utility, open the Start menu, point to All Programs, and then point to Accessories. Next, point to System Tools, and then select the Disk Cleanup command.
Disk defragmenter
Over time, the files that belongs to specific programs may be stored all over the hard disk where the space is available. This tool will help you to tidy up the files and keep them within the correct folder to save time for the system to find and read the files.
To run the Disk Defragmenter on your hard disk, open the Start > All Programs > Accessories > System Tools > Disk Defragmenter command. In the Disk Defragmenter window that opens, select the volume you want to defrag and then select the Defragment button.
Apart from above two tools, you can also refer to third party program to clean up your disk and keep it healthy. A registry cleaner and system optimizer will not only do above for you, but also clean regularly and automatically, and scan your registry errors and other junk files to free up space in your hard disk.
