Data Recovery Guidance

Welcome to Data Recovery Guidance!

If you’ve found your way to this site then you are someone who is familiar with that sinking feeling; that ice melting in the pit of your stomach when you first realise you’ve lost some extremely important data.
Data loss can be an absolute catastrophe, or it can be a well-managed accident if the proper contingencies are in place. Data recovery is clearly your first course of action. But what actually is that, and what does it involve?

In order to discuss data recovery, one must define data loss. Data loss is data that has become inaccessible due to damaged, defective or corrupt media. The recovery actions will be unique depending on which of those three scenarios has caused data to be lost. In some instances, the solutions are relatively easy and very successful; in others, the complexity of recovery is costly, intrusive and the results are not always positive.

In the simpler forms, data loss is perceived by an end user when their computer fails to boot, or when they have accidentally deleted and purged desirable files. In these cases, their hard drive can be connected secondarily to another computer, or their computer can be booted to a special, bootable CD-ROM or flash disk. In either case, the goal is to present to the disk to the system secondarily, where it is not depended on by the operating system for critical system files. This allows the drive to be scanned without the risk of the files being overwritten through normal use of the drive. If the operating system on the source drive has failed, recovering the files can be as simple as dragging and dropping personal data to another location. Where deletions have occurred, there are several programs for free and for purchase that will scan the file structure, identify the deleted data and restore them to the file system, so as long as they have not been overwritten. The sooner the machine is disconnected from power after the accidental deletion has been made, the greater the odds that such a program can restore the files.

When data has become corrupt at the software level, similar disc scans can be performed to attempt repairs to the damaged files. These scans can be initiated and run by the operating system, such as the check disk utility, or can be done from a 3rd party application that may have a more robust repair capability. These programs try to return the files to their original state and structure, but depending on the file type, the corruption may be too extensive to return the file to full functionality. These are especially likely in cases where the file is a program or part of a program executable, whereas text documents and similar can retain some usefulness after corruption.

In the worst cases, data loss is caused by failure of the hardware, or by irreparable damage from dropping, impact and so forth. When the hardware itself is to blame for the data loss, an end user or technician has little ability to affect repairs himself, nor much of a chance at recovering data. Old tricks, such as putting a clunking hard drive in the freezer for a few hours, simply do not offer any benefit. The only effective choice is to ship the defective hard drive to a service that specializes in data recovery; they can physically examine the drive, repair components as necessary, and even remove and relocate the platters themselves into a known-good equivalent unit, and copy the data bit by bit to another medium.

This extracted data can then be analyzed by an array of proprietary programs that can attempt to reconstruct the data as best they can into something useful. It is possible that the physical issues with the hardware could have caused irreparable corruption of the data contained on the drive. Hence, such services offer no guarantees as to the results of their work, although in many cases some useful data is recovered. Such services tend to be very costly, reiterating the need to maintain frequent, up to data backups of all-important data.

So, in summary it can’t work miracles, and some data may be truly unrecoverable – but the technology is really rather remarkable, and Data Recovery clients are continually surprised by how much was able to be recovered from what seemed like a hopeless situation.

Of course, knowing what needs to be recovered from what, and how to go about it, is the first step. This is where we come in.

You’ll find here a wealth of resources on all things related to data recovery. Where to find cheap and competent data recovery services,the different methods of data recovery depending on hardware, and also when and how to recover lost data yourself, with the use of software.
