File corruption is a common situation computer users face. Reasons that files get corrupted include virus attacks, malfunctioning software, bad sectors in the disk and media corruption. Data gets corrupted from natural disasters and human error too.

About 50% of data loss is caused by hardware failure, such as a hard drive. It's essential that that you immediately shut down your system if you suspect hard drive corruption. A disk failure can take place in the course of normal operation or due to an external factor such as exposure to fire or water or high magnetic waves, or even after suffering a sharp impact. Hard drive failure can be catastrophic or gradual. Catastrophic disk failure can be a drive no longer being detected by CMOS setup or a drive failing to pass BIOS POST which will result in the operating system no longer seeing it.

Gradual hard drive failure can be diffficult to diagnose becuse it can caused by many other computer issues, such as malware. Symptoms include a slowing down of the PC because gradually failing areas of the hard drive require repeated read attempts before successful access. A steady increase in bad sectors can be a sign of a failing hard drive.

1. Free up disk space - A disk cleanup tool helps you free up space on your hard disk to improve computer performance. These tools identify files that can be safely delete, and then enables you to choose whether to delete some or all of the identified files.

2. Speed up access to data - Disk fragmentation slows the overall performance of a system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. Computer esponse time can be significantly longer.

3. Detect and repair disk errors - In addition to running a disk cleanup and disk defragmenter to optimize computer performance, check the integrity of the files stored on your hard disk by running an error checking utility. For freeing up disk space, speeding up data access and repairing disk errors we use and highly recommend TuneUp Utilities - Version 2010. Buy Now!

4. Protect a computer against spyware - In addition to stealing personal information, spyware can hamper your computer's performance. We recommend STOPzilla's award-winning technology which removes and prevents spyware, adware and all forms of malware. STOPzilla! Download Now.

5. Add memory to a system - Adding RAM is often the most cost-effective way to speed up a sluggish computer. Computers that had more than enough RAM when new routinely have trouble keeping up with the demands of the latest programs. In addition, new operating systems almost always require more memory.
