Troubleshooting a laptop or a desktop computer can be a daunting task but with a systematic approach you can learn to cope with some of the headaches when facing a computer crash. There are so many possibilities and scenarios that can cause your computer or laptop to go down. When problems occurs the first thing to do is to determine if you have a software or hardware problem, finding out if the problem is actually a physical issue like a bad component such as memory, hard disk, motherboard etc. or a software issue like a bad driver, a virus or spyware, corrupt system files etc.

Once the backup is done and most important configuration are written down, again if your operating system is somewhat accessible. You are now ready for the following step, formatting (wiping your hard disk clean) and re-install the operating system, providing that you have your official operating system license cd, then once the operating system is installed, you will need to re-configure all your internal and external peripherals such as: sound card, video card, network card, modem, printers, scanners etc.(keep in mind that on some systems depending on the chipset of the motherboard, you will be spared from installing some drivers, nevertheless it is always advisable to get the latest drivers from the manufacturers sites. Your final step will be to restore all backed up data, and finalize the installation of all additional software and other downloads that you may require. Don’t i repeat please don’t forget your email and address book backup too. Once the computer is formatted, it will be impossible for you to go back and recover lost data if you are not a professional with specialized tools and software.

Did your computer just come to a grinding halt and freeze at a blue screen showing a lot of messages in white? You’ve just encountered the famous Blue Screen resulting from a Windows Stop error - more colorfully known among the Windows Operating System user community as the Blue Screen of Death or BSOD. If this has just happened to you don’t despair, help is at hand!

4. Disconnect New/Faulty Hardware - If you are unable to use the last known good configuration, the probability of a hardware error is very high and you may need to disconnect any hardware installed just prior to the crash or check if any of your hardware is faulty. Once the offending hardware device is removed or replaced, the problem should be fixed.

So your computer has crashed and you feel like you have lost everything!  Fret not!  There may be help just down the road.  There is hope that your data can be recovered.  Check the phone book or do an Internet search for “hard disk recovery Coventry” to locate a facility close to you.

What exactly is data recovery?  Data recovery is generically the process of retrieving information stored on a computer’s hard disk when the information cannot be accessed by normal means.  It may be that there is physical damage to the hard disk itself, or it may be that files required by your operating system to access the files has become corrupt, damaged, or even missing. 

About Physical Damage to Your Hard Disk

Hard disks can become physically damaged for a number of reasons.  Often what occurs is that the a motor necessary to properly run the hard disk fails.  Another common problem is that dust particles have made their way into the hard disk case and logged themselves between the read/write head and the platter.  The platter is the part of the hard disk that looks almost like a regular CD.  Repair to your hard disk if it become physically damaged is not for the novice and often should not even be attempted by someone very knowledgeable if they don’t have the right type of facility.  To properly take apart and repair a hard disk, you should find a company that has a “cleanroom” to ensure no further damage is done to the hard disk.  Many warranties will be voided if you choose to try and fix the hard disk yourself or if you take it to a professional who does not use an appropriate ISO-5 cleanroom.  When you call about data recovery Coventry, be sure to inquire what facilities the company uses if opening your hard disk for repair becomes necessary. 

About Logical Damage to Your Hard Disk

Often physical damage is paired with logical damage, or you may have logical damage alone.  Logical damage to your hard disk is when the file structure becomes somehow incomplete or inconsistent.  This can be caused by a variety of reasons including (but certainly not limited to) the following

• Viruses or other malware
  
• Loss of power during an install or uninstall
  
• Hardware issues
  
• Damaged or missing drivers
  
• Improper install or uninstal
  

There is software readily available to help diagnosis and correct logical errors.  Often these programs come pre-installed on your PC such as Disk Utility for Macintosh, fsck utility for Linux, and chkdsk for Windows.  Typically logical data repair comes in one of two forms:  consistency checking and data carving.  Consistency checking is when a software scans a hard disk to ensure that all file associations are intact and are consistent with the specifications for your machine.  Data carving involves recovering data when file allocations are no longer intact.  Many times minor logical damage can be achieved using software at home, but not always.  If you find that your problem is not fixed quickly by free software, take your computer in to a pro.  You may do more damage or make the files permanently unrecoverable if you do too much tinkering on your own.  Data recovery Coventry services can recover data due to all kinds of logical damage and more importantly, they can make sure the root cause of the problem is corrected so you do continue to have the issue.

Data recovery

Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media formats such as hard disk drives

Recovering data from physically damaged hardware can involve multiple techniques. Some damage can be repaired by replacing parts in the hard disk. This alone may make the disk usable, but there may still be logical damage. A specialized disk imaging procedure is used to recover every readable bit from the surface. Once this image is acquired, the image can be analyzed for logical damage and will possibly allow for much of the original file system to be reconstructed.

Recovering data after logical damage

The physical damage is logical damage to a file system. Logical damage is primarily caused by power outages that prevent file system structures from being completely written to the storage medium, but problems with hardware (especially RAID controllers) and drivers, as well as system crashes, can have the same effect. The result is that the file system is left in an inconsistent state. This can cause a variety of problems, such as strange behavior (e.g., infinitely recursing directories, drives reporting negative amounts of free space), system crashes, or an actual loss of data. For instance, when a hard drive’s read/write head begins to click, most end-users will associate this with internal physical damage.

Microsoft included the recycle bin idea in the Windows 95 distribution. It keeps all the files that have been deleted intentionally or by accident. Presently, the content of the recycle bin can be verified before permanent deletion, but with earlier operating systems the only solution to recover a deleted file was to start a recover procedure.

Using the directory properties the capacity of the recycle bin can be enlarged according to your needs. However, keep in mind that a larger recycle bin means less space for programs and data so it is very important to keep the balance.

Virus: A virus is a computer program that has been coded to replicate itself and infect a computer
The best free anti-virus is AVG anti-virus which can be found at http://free.grisoft.com/ .

Trojan horse: Trojan horse or just Trojan is a program which looks legitimate but performs illegitimate actions such as granting full access to the intruder, installing a keylogger, disabling security software and as an invisible downloader and spywares. Spybot Search and Destroy is a free program that can find and delete Trojan horses and spywares. It can be found at http://www.safer-networking.org/en/download/index.html

Adware: Adware (advertising supported software) is a software bundle which automatically downloads and displays advertisements to a computer in which it is installed. Adwares can be classified as privacy invading software. It is seen as a way to recover development costs by software developers

. The best program to combat adwares is Ad-Aware 2007 and it can be downloaded at http://www.lavasoftusa.com/products/ad_aware_free.php

Rootkit: A rootkit is a program which has been coded to take complete (or root) control of the system without the user’s knowledge. Rootkits take full control of the operating system and therefore cannot usually be removed by anti-virus software. Rootkits usually modify the boot sector of the operating system or disguise as drivers and load during boot up. As a result, it is usually hard to delete them. The most recommended rootkit remover is Sophos Anti-Rootkit without the user’s knowledge. A virus spreads from computer to computer by infecting network files as well as CDs, USB drives, and other forms of removable media.

Definitions and A Brief Introduction to the Dangers of Malware 1. Introduction. The ever increasing use of the Internet means more and more computers can be accessed by others through file transfers, e-mails and websites, leaving them susceptible to infection from an increasing number of viruses, Trojan Horses, worms, adware, spyware, etc. These terms can be very confusing as each one is different in characteristics and will cause different problems or damage to your computer. People will tend to be more on the lookout for these threats if they understand what they are and their potential dangers. This article attempts to clarify the meaning of each of these terms. After reading this article it is strongly suggested that you visit www.bestvalueonline.biz/clearspyware.html for further information on how to protect your PC against this dangerous class of software. Your bank account and identity are ultimately at risk if you do not take action. 2. Malware Many normal computer users are still unfamiliar with the term ‘malware” and most never use it. Instead, "computer virus" is incorrectly used, even in the media to describe all kinds of malware, though not all malware are viruses. Rather than being defined by any particular features, software is considered malware if the perceived intent of the creator is to cause damage. Malware includes computer viruses, worms, trojan horses, most rootkits, spyware, dishonest adware, and other malicious and unwanted software. In law, malware is sometimes known as a computer contaminant, for instance in the legal codes of California, West Virginia, and several other American states. Malware is software designed to infiltrate or damage a computer system without the owner’s informed consent. It is a shortened combination of the words malicious and software. The expression is a general term used by professionals in the computer industry to cover a variety of hostile, intrusive, or annoying software or program code. Malware should not be confused with defective software, that is, software which has a legitimate purpose but contains harmful bugs. 3. Trojan Horse or Trojan In the context of computing and software, a ‘Trojan horse’, or simply ‘Trojan’, is a piece of software which appears to perform a certain action but in fact performs another such as a computer virus. Contrary to popular belief, this action, usually encoded in a hidden payload, may or may not be actually malicious, but Trojan horses are notorious today for their use in the installation of backdoor programs. Simply put, a Trojan horse is not necessarily a computer virus. Unlike such malware, it does not propagate by self-replication but relies heavily on the exploitation of an end-user. Therefore, a computer worm or virus may be a Trojan horse. The term is derived from the classical story of the Trojan Horse.

Data Recovery is exactly what it sounds like - a way to recover important information that was lost from a computer crash, hard disk malfunction, or virus attack. No matter the scale, big corporation database recovery or single user retrieval of files from spontaneous deleting. Data Recovery software can be developed, installed and removed from existing systems to retrieve lost data or partial data and minimize damaged caused to the system.

In the field of information technology, data loss refers to the unexpected and unwanted loss of data or information and there are several possible root causes. These following most common errors and technical glitches may cause to corrupt your computer and data loss occurs:

Whenever a user encounters a data loss issue due to physical crash of the hard drive, he tries to find the ways to completely recover the lost data from the damaged hard drive. Most of the users browse the internet to find the best solution. But when the user searches for the data recovery service companies, hundreds of results appear on the computer screen that can fulfill the requirement. These results leave the user in a confused state of mind as it becomes very difficult for the user to differentiate between the never-ending lists of data recovery service companies.

Below are the points that any user should notice before choosing any data recovery service:

Irrespective of being a PC or a Mac the computer system behavior and consistency are dependent upon certain factors. These factors are broadly divided into software factors, hardware factors and the surroundings. The common software factors leading to a logical failure are: i.) System files responsible for handling control to the operating system missing or corrupt ii.) Unsigned drivers or drivers trying to access read only system area iii.) Operating system files corruption due to incomplete automatic update, malicious software The common hardware factors leading to a physical failure are: i.) Problems related to mainboard in terms of the chipset or connector, power supply issue like incompetent power supply to run the hardware setup ii.) Problems related to hard drive itself or the data or power cables iii.) Improper setup of hard drive cooler fans (if any) The common surrounding factors leading to data loss are: i.) Heat dissipation issues related to closed or poorly ventilated surroundings like in a basement or store ii.) Moist surroundings leading to the formation of thick dust layers and thus increasing heat iii.) Direct sunlight leading to extra heat and thus hardware failure We should logically negate these scenarios so that we can narrow down to the root cause of the problem and take corrective measures. In case we find that the data loss is due to any logical failure, we can use data recovery software as they are programmed to meet the challenges due to all kind of logical crashes. They scan through the file system, locate all the files which are marked as deleted and are distributed as fragments across the partition, logically rearrange them as per the file system information and then recover them. The data recovery software are indispensable in cases like file system corruption, hard drive formatting operating system corruption, accidental file deletion or malicious software like virus, spyware etc. We can perform a ‘Do It Yourself’ data recovery using these utilities as they are self descriptive and User friendly. We need to install the data recovery software on another hard drive which is bootable. We can also use a different working system preferably using the same operating system platform as for MS Windows. Then, we can attach our hard drive to the same for scanning. For attaching the hard drive we nowadays use USB 2.0 Hi Speed or IEEE 1394/Firewire Cables, Attachments or Enclosures. The same can be achieved by a Master and Slave setup that requires hard drive jumper operations and thus is a little complex. We should avoid any other jumper operations as of the mainboard as they may lead to unstable system behavior based on BIOS settings. We should always save the recovered data on a healthy hard drive. In case of data loss due to hardware failure where the hard drive is either not getting powered or can not be recognized by the BIOS, we need to go for hard drive recovery service. The data recovery service is personalized help, delivered by data recovery experts. Such experts can extract your data in all possible scenarios of physical data loss.
