Data Corruption - Bane of Technology
The last two decades have seen a boom in technology. The spread of the personal computer has been phenomenal. Activities based on the use of the computer have been on an upswing.
Computers have eased lives to a great extent. The flip side is that along with the convenience, computers have to face various threats of data corruption both externally and internally.
Causes Of Data Corruption
Data corruption is basically the weakening or damage of data stored in the computer caused by human, hardware and software fault. Various symptoms of data corruption include:
- Repositioning of files and folders
- Invalid file format
- Renamed of files with garbled characters
- Changing of file attributes
- Frequent computer crashes and hangs
- Sluggish disk operation
- Busy disk activities even with fewer applications running.
There are various causes of data corruption. Some of them are:
Bad Program Exits
One of the most widespread causes of data corruption is bad program exits. Bad exits mean switching off or restarting the computer without using the proper shutdown protocol. You might need to shut down improperly due to hurry. At times, software locks and system errors can immobilize your machine.
In such cases, you may need to restart your computer by physically pressing the restart button. When a file is written half and the process is stopped, the file creation becomes partial and as a result, the file may be corrupted. To correct this problem, always follow proper shut down practices. An uninterruptible power supply defends your computer in an event of a power failure and power
Malware Infection
Malware infection ascribes to the second most general causes. Malware usually refers to any software program that is intended to inflict damage to a system. Some viruses replicate themselves and overwrite areas of raw disk with garbage.
The malevolent ones carry out unwanted actions such as deleting files, varying data, invigorating typos and in the course of doing so, damaging your document files and operating system files.
Additionally, virus slows down your computer when it executes its own code thus drawing extra processor cycles. Particular strands of virus such as a boot sector virus implant themselves in system sectors and corrupt the partition sectors leaving your computer damaged when you turn it off.
Therefore, getting rid of malware is a vital job for any user. If you frequently download programs from the Internet, you need to be especially cautious and only opt to download from dependable sources.
You must also install antivirus software to guard your system and to eliminate any viruses and spyware. Last, you will also need to persistently update software and operating system patches so you could be sheltered against any vulnerabilities due to operating system or software.
Poorly Written Software
You have come across an interesting article, which endorses new software. You are enticed to download and try it for yourself. But are you sure that the program is virus free and safe? Poorly written software is a valid cause for data corruption.
Many freeware and shareware available online are written poorly and thus result in system instability and various other problems. One of the most exasperating problems is when the programs adapt your system settings without your permission and thwart you from removing them from your computer totally.
More often than not, they leave a mound of garbage that occupies superfluous storage area in your hard disk and system registry. The inferior ones include utilities, which furtively contain spy ware. So before you take a decision to install something in your computer, make sure that you check out on the reviews, joint discussion forums etc. and do your homework thoroughly.
