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"
"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
