You Lost Your Data... Don't Panic

You Lost Your Data... Don't Panic
Emanuele Allenti

Inability to access your data stored on the data storage device could be caused by many reasons, from those that are easy to fix to those which are completely impossible to fix. If the damage is irreversible then data loss will occur. The causes of the failure of your hard drive or CD-ROM drive could vary from a bad connection due to a loose wire (which is easily recoverable) to damage to the media itself, which could still be recoverable in many cases.

As in the medical profession, the first principle of data recovery is: "do not harm".

If you are facing a data loss situation, what not to do is very important!

  • Do not power up a device that has obvious physical damage.
  • Do not power up a device that has shown symptoms of physical failure. For example, disks that make "obvious mechanical fault noises" such as ticking or grinding, should not be repeatedly powered on and tested as it just makes them worse.
  • Activate the write-protect switch or tab on any problem removable media such as tape cartridges and floppies. (Many good backups are overwritten during a crisis.)
  • Do not use free software. This is very important. Free data recovery software can be extremely dangerous and ruin your chances for a successful data recovery. Many companies offer free data recovery software -- also called Do-It-Yourself (DIY) data recovery software -- available for download on their website.

Even the best programs only work in very specific situations. While these free tools that are available may help, they usually only help if you are encountering one of a very few specific data loss situations.

Some programs may cause further or permanent data loss. While these programs are provided with good intention, even when carefully used these utilities may cause recoverable data to be permanently lost and may cause the loss of additional data.

Anyway, there is something you CAN do; if you are having data access problems and your media has no symptoms of physical failure or damage, try and check some obvious issues before deciding if you need data recovery:

  • Are the power and disk cables properly connected?
  • Is configuration or disk information correct?
  • Try the defective unit with a different adapter/controller interface or on a different computer.
  • Is there an experienced technician at a local store or the company help desk that you can consult, if these steps are beyond your capabilities? (Make sure whoever is in contact with your data loss situation is fully aware that they should do nothing during their troubleshooting that will risk hurting your data.)

Doesn’t work? Don’t panic; if the damage occurred to the drive's electronics, it most likely could be fixed. If the damage occurred to the, for example, system areas of the disk, leaving the data zone intact, those data could be theoretically, and (in some cases) practically, recovered by a professional.

Look on the Net for data recovery companies, ask them questions, explain them your situation. In most cases they will be able to understand your problem and fix it for a fair price.

What Is Data Recovery

What Is Data Recovery
Jakob Jelling

Data recovery is the retrieval of inaccessible or contaminated data from media that has been damaged in some way. Data recovery is being increasingly used and is an important process nowadays.

There has been a lot of progress in increasing the memory capacity of data storage devices. Therefore data loss from any one incident also tends to be very high. The relevance of lost data can vary greatly. Maybe you have had the experience of storing a homework assignment on a floppy disk only to have it missing on the day the assignment in due.

Consider the fact that a large amount of businesses nowadays have vital organizational related data stored on machines. Also hospitals store data on patients on computers. Large amounts of websites nowadays use databases technology to enhance their websites and make them more dynamic. Php and MySql use has been on the rise on the Internet. Database failure is not uncommon and so it is not a fail proof method of storing information.

Companies have high reliance on computer technology to write and store data relevant to their business operations. Thus the data being stored can have a great deal of impact on personal lives and operations of companies.

There can be several causes of data loss.

Data loss can occur from unexpected incidences including national tragedies such as floods and earthquakes.

Often power failure can cause loss of data from hard drives. Sudden power surges can also cause a lot of damage to a computer’s hard drive.

Accidentally deleting a file or formatting a hard drive or floppy disk is a common reason for data loss.

If you have accidentally lost any important documents there are several steps you can take. Remember that if you have accidentally erased a file, it may not have vanished from your computer. It may have left an imprint in a different format on the computer’s hard drive or other storage devices. Recovering the data involves locating it and transforming it into human readable form.

Not all data may be recoverable.

You can either hire professional service to help you solve your problem or attempt a recovery on your own.

You can carry out data recovery operations on your own computer if you know what you are doing. There is data recovery software widely available that can assist you in the process.

Data recovery can become complicated if you overwrite on the storage device that has the lost data. Therefore if you do not know what you are doing, it is advisable to contact a professional service firm.

Data recovery professionals are experts in recovering data from all sorts of media and from a variety of damages done. There are many specialists out there who have years of experience in the IT field. The kind of data recovery operation to use will depend a great deal on the storage device and other variables such as the amount of damage done or the operation system used such as Macintosh, Windows or Linux.

There are some cases where it may be impossible to recover any data. However do not fret as the odds lie in your favor since a high percentage of data recovery operations are successful.

Preventing data loss

Of course the best way is to prevent data loss in the first place.

Data backup allows for restoring data if data loss occurs. Even ordinary pc users can set up their computer to carry out regularly scheduled backup operations. In the event of a hard drive crash or an unwise change in settings by an uninformed user, the restore tool can be used to retrieve deleted data or to restore the computer’s settings from an earlier time.

For the back up process to be useful it should involve several reliable backup systems and performing drills to make sure the data is being stored correctly. Additional protection methods from data loss include making sure that the hard drive is protected from damages from the external environment. This includes protection from sunlight and temperature extremes.

Also plugging in your pc into a surge protector rather than an ordinary outlet can give your computer a protection layer from electricity fluctuations. Keep your virus protection up to date. Also remember to keep your backup data separate from your computer.

Nevertheless a lot of companies will go through a disaster and experience data loss. The best thing to do is not to panic and also not to ignore the situation. The quicker you rectify the situation the better. Counting on data loss will help you be prepared for any such event.

Coping with a Serious Data Loss from your Computer Hard Drive

Coping with a Serious Data Loss from your Computer Hard Drive
Darryl Peddle

Data loss is an expensive reality. It's a hard fact that it happens more often then users like to admit. A recent study by the accounting firm McGladrey and Pullen estimates that one out of every 500 data centers will experience a severe computer disaster this year. As a result, almost half of those companies will go out of business. At the very least, a data loss disaster can mean lost income and missed business opportunities.

The other side of data loss is the psychological and emotional turmoil it can cause to IT managers and business owners. Despair, panic, and the knowledge that the whole organization might be at risk are involved. In a sense, that's only fair, since human error is one of the two largest contributing factors in data loss. Together with mechanical failure, it accounts for almost 75 per cent of all incidents. (Software corruption, computer viruses and physical disasters such as fire and water damage make up the rest.)

Disk drives today are typically reliable. Human beings, it turns out, are not. A Strategic Research Corp. study done in 2000 found that approximately 15 per cent of all unplanned downtime occurred due to human error. A significant proportion of that happened because users failed to implement adequate backup procedures, either having trouble with their backups, or having no backup at all.

How does it happen that skilled, high-level users put their systems - and their businesses - at such risk?

In many cases, the problem starts long before the precipitating system error is made, that is, when users place their faith in out-of-box solutions that may not, in fact, fit their organization's needs. Instead of assessing their business and technology requirements, then going to an appropriate engineered solution, even experienced IT professionals at large corporations will often simply buy what they're sold. In this case, faith in technology can be an vice instead of a virtue.

But human intervention itself can sometimes be the straw that breaks the technology's back. When the office of a Venezuelan civil engineering firm was devastated by floods, its owners sent 17 soaked, mud-coated disks from three RAID arrays to us in plastic bags. A tough enough salvage job was made even more complex by the fact that someone had frozen the drives before shipping them. As the disks thawed, yet more damage was done. (After eight weeks of painstaking directory-by-directory recovery, all the data from the remaining fifteen disks was retrieved.)

Sometimes, the underlying cause of a data loss event is simply shoddy housekeeping. The more arduous the required backup routine, the less likely it will be done on a regular basis. A state ambulance monitoring system suffered a serious disk failure, only to discover that its automated backup hadn't run for fourteen months. A tape had jammed in the drive, but no-one had noticed.

When disaster strikes, the normal human reaction is panic. Because the loss of data signifies critical consequences, even the most competent IT staff can jump to conclusions, and take inappropriate action. A blank screen at a critical time can lead to a series of naive decisions, each one compounding the preceding error. Wrong buttons get pushed, and the disaster only gets worse. Sometimes the pressure to correct the system failure speedily can result in an attempt to reconfigure an entire RAID array. IT specialists are typically not equipped to deal with crisis modes or data recovery techniques. Just as a good physician is trained to prolong life, the skilled IT specialist is trained to keep the system running. When a patient dies, the physician turns to others, such as nurses or counselors to manage the situation. When significant data loss occurs, the IT specialist turns to the data recovery professional.

Data recovery specialists are innovative problem solvers. Often, the application of basic common sense, when no-one else is in any condition to apply it, is the beginning of the journey towards data recovery. The data recovery specialist draws on a wealth of experience, married to a "never say die" attitude, and a comprehensive tool kit of problem-solving procedures. Successful recovery outcomes hinge on a combination of innovative logistics, applied problem-solving, and "technology triage," the process of stabilizing an affected system quickly, analyzing and treating its wounds, and preparing it for surgery. The triage process sets priorities, such as targeting which files are needed first or which are absolutely vital to the functioning of the business, and establishes whether files might be recovered in less structured formats (such as text-only), which may be desirable when time is crucial.

The art and science of professional data recovery can spell the difference between a business' success or its failure. Before that level of intervention is required, though, users can take steps to ensure that the probability of a data loss disaster is minimized.

Basic to any business technology plan is a regular fire-drill procedure. Back-up routines may be in place, staff may assigned to specific roles, hardware and software may be configured - but, if the user isn't completely sure that everything works the way it should, a data loss event is inevitable. Having adequate, tested, and current backups in place is critical. A hardware breakdown should not be compounded by human error - if the malfunctioning drive is critical, the task of dealing with it should go to a data recovery professional.

Just as data loss disasters are rooted in a combination of mechanical failure and human error, so, too, the data recovery solution lies in a creative marriage of the technological and the human. The underlying philosophy of successful data recovery is that technology is something to be used by human beings, not something that uses us.
