Data Recovery - What To Do When Your Hard Drive Fails

<div style="text-align: justify;">How many times have you experienced that sickening feeling when your hard drive suddenly fails? How many times have you experienced that your hard disk just does not boot and all the data may be gone forever? A hard drive failure is one of the most common problems and worst nightmares faced by computer operators all over the world. Precious data is lost either at home or in big corporate environments. What can be done in these situations? Well, there are certain solutions that can be performed by you in order to revive your hard drive. We will talk about the solution later. First, let us discuss why a hard drive fails. Whether the data on the hard drive can be recovered or not depends on the extent of the problem. A hard drive can be damaged due to firmware corruption, electronic failure, mechanical failure or a logical failure. Many times your hard drive may lose data due to the combination of the above mentioned factors. A hard drive may also develop bad sectors due to which the data on those sectors is lost or becomes unreadable. </div><a name="more"></a>Firmware refers to the information used by the computer to interact correctly with the hard drive. If the firmware fails or becomes corrupted, then important data on the hard drive is lost. In case of an electronic failure there maybe occur an electrical surge that can knock out the controller board on the hard drive and make it unusable. However data can be recovered by data recovery experts who use special data recovery software. Swapping the controller board with another one can prove to be dangerous as the information on the controller board is unique to the hard drive on which it is fitted. In comparison to electronic failure a mechanical failure can turn out to be worst as data recovery can almost become impossible. Mechanical failure includes head crash and also read/write head failure. Head crash can occur due to physical shock, power surges and movement of the computer. Next come the logical errors. Logical errors have nothing to do with the hardware part. Logical errors can occur due to corruption of the file system on the hard drive or improper entries in the file allocation table. In case of hard drive failure it is vital to call the data recovery experts. In most cases, the information on the hard drive is important and you cannot bear to lose it. The experts enhance the possibilities of hard drive recovery in the case of failure of hard drive due to software malfunction, virus attacks and other reasons mentioned above. Data can be recovered on any type of operating system including all versions of Windows as well as Apple Macintosh, Novell, Linux, Unix and also on all types of file systems like FAT, FAT32, NTFS, NTFS5, HFS, HFS+, NWFS, EXT2 and EXT3. The experts may take the hard drive to their workshop in order to recover the lost data and then return it to you in a few days. Most of the data recovery experts have their own laboratories that are involved in testing the hard drives and repairing them. Loss of data is the last thing that you as the customer would ever want. This is where the data recovery experts come into the picture. They cannot extract only data from hard drives, but recover data also from tape drives, cds, dvds and other important storage media. You as the consumer can take up some preventive measures like backing up all your important data at least once a week. Windows has its own feature rich backup program. There are other backup software programs available in the market that can avert a possible disaster. Besides the concern of recovering your data, another problem is the time it may take for an expert to help. This can be a slow and tedious process. I recommend having a second complete computer source such as a laptop (for portability) that you can continue your work. This way you are never completely down and you can share important data between the two.

Data Recovery - Your Next Option To Safeguarding Information

<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">The realization about the need to prepare for safeguarding crucial data on your hard disk may come a little too late when the computer or the hard disk has crashed. Data loss could mean, for a small business, going out of business unfortunately, sometimes permanently. Rebuilding years of data is out of question. It is pertinent to know the whys and hows of data loss in order to understand data recovery better. Important Causes of Data Loss What you hoped will not occur, perhaps because of no reason, could always hit you hardest unless you are safeguarded against them. Computer running slowly could be because of spyware scrupulously installed could be working behind screens to destroy or transmit data to their masters eventually causing hard disk to crash. Others like electric storms, power surges, mechanical failures, fires & floods and user errors (sometimes in disregard of warnings) could affect your computer without any or sufficient warning. <a name="more"></a>You could also loose data because of sudden but unintended deleting of files or programs. Accidental disk format, virus attack, partition loss are some more causes for data loss. Data Protection Data protection is the best policy than ruing over the loss. You can make use of trusted data backup software which automatically backup your data regularly, if you can’t do it yourself manually. Keeping backup of backups will safeguard you against the worst eventualities, too. Turn off your computer immediately as you hear strange noises like creaking run of hard disk. It is also wise to unplug power cords, modem and telephone cables when you are going out of home or office for a long time. Data Recovery The first thing you need to understand when dealing with data recovery is not loosing cool. Never act in haste and don’t attempt data recovery yourself unless you are an old hat at that. Call for professional help from your area and who you know. Data recovery software does a neat job in most of the cases. There are quite a few reliable softwares available, no matter what platform your computer operates on. Data recovery softwares are available for Mac, Windows, Linux, and so on. Don’t attempt to use the software yourself out of gut feeling. If you must, check for user friendly personal packages. An average company in US alone spends anywhere between $100,000 and $1 million in total for desktop-oriented disasters. This should more than emphasize the need for data safety and disk recovery. </div>

Data Recovery and Your Computer

<div style="text-align: justify;">Have you ever wondered if what you know about data recovery is accurate? Consider the following paragraphs and compare what you know to the latest info on data recovery. Sooner or later your company could become the victim of a natural disaster, or something much more common like a lightning storm or downed power lines. Just because your company may be a small business doesn't mean it's immune to data disasters. If a small business does not have a good and tested disaster recovery plan in place when disaster hits they may never fully recuperate and it may even cause them to go out of business. Sometimes even a data recovery service is unable to be of any help.  </div><a name="more"></a>Following are some questions that should be answered in order to give you some idea of what you need to do to that will help you if you do have a data disaster situation. Do you know where your company's most important data files are located? Are these files being backed up and by what means? How often do you run these data backups and are they verified and tested? Do you have automated controls that correctly and on a consistent basis do the backups? Do your data backup tapes go off-site and how often? Do you have some kind of security against tampering or theft of your data backups? Do you keep your servers, routers, hubs, and phone system controllers in locked areas to keep them more secure? Does just anyone have access to your servers and your other technology assets or do you limit access to at least two, but no more than four people? Do you run a locally securable operating system, such as Microsoft Windows 2000 Professional, Microsoft Windows XP, or Microsoft Windows NT Workstation 4,on the company's desktop PCs and notebooks? Do you have any confidential data stored locally on any desktop PCs or notebooks? Are any of these systems running an inherently in-secure operating system, such as Microsoft Windows 9x or Microsoft Windows Me? Do you prevent unauthorized boot-ups or tampering with BIOS configuration settings by using power-on passwords? On your desktop PCs and notebooks, how are main updates, service packs and releases kept current? The bottom line is that you can't plan when a data disaster may strike but taking a few steps beforehand may help with your company's survival in the days and weeks following a disaster.

Data Recovery/Datenrettung & Securing Data On Computers

<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">Data recovery or Datenrettung is the process by which the data is recovered from damaged or inaccessible storage media. Data recovery is done from storage media like CD´s, DVD´s, Floppies, Hard disks, Magnetic tapes etc. There are two reasons due to which the data becomes inaccessible. They are logical damage and physical damage to the storage media. Physical damage to storage media can occur in many ways. Magnetic tapes can break, get crumpled or dirt may settle on the tapes. CD´s and DVD´s can have scratches or the metallic layer may get damaged. Magnetic heads in hard disks can crash or motors may fail. The floppy is notorious for failing frequently due to bending, overheating, cold, dust etc. <a name="more"></a>There are other reasons like fires, electrical surges etc that can cause data to become inaccessible or lost. There are many methods by which data can be recovered from magnetic media or optical media. The methods most commonly used are Magnetic Force Microscopy (MFM), Scanning Probe Microscopy (SPM), Magnetic Force Scanning Tunneling Microscopy (STM) etc. In these methods a sharp magnetic tip is placed closed to the surface to be analyzed. It interacts with the stray magnetic field. An image of the data is generated and then repairs are carried out on logical damage and thus the data is recovered. Many companies carry out data recovery. Logical damage is the damage to the file system. It is not physical but a software problem and also tells us that we need to be cautious and have a quality system for data recovery, datenrettung. It generally occurs due to power cuts, system crashes etc preventing file system structures from being written resulting in file system being left in an inconsistent state. Logical damage is more common than physical damage. This may cause strange behavior like infinitely recurring file directories, loss of data, system crashes, hard disks reporting negative space etc. The end result is that the operating system cannot mount the file system. Most operating systems come with repair facilities like, Linux has fcsk utility, Mac has disk utility and Windows has chkdisk facility. There are other specialized programs available which have better repair facilities than the operating systems. There are also other systems called journaling file systems like NTFS, EFS (used in Windows XP), ext3 and xfs which can be reverted back to their earlier consistent state. These file systems reduce the amount of data loss. Data back up is the best way to prevent loss of data and it´s the most common system for data recovery, datenrettung. The simplest method is to keep data on drives on which the operating system is not loaded. The other method is to write data on magnetic tapes, CD’s or DVD´s or have online backup. Backups are very important for databases. Data backup is of 3 types. Full backup means backing up all data. Incremental backup means backing up of only the files that have changed. Differential backup is a mixture of these two. There is another method called continuous data protection in which when data is written to a disk, it is also written to another computer in a network. Most private persons with a computer do nothing in advance, they just use their computers. Too late, when an incident has happened they learn about data recovery or datenrettung. </div>
