A computer hard drive or any flash media uses a type of memory call non-volatile memory. Non-volatile memory means that the information stored on that drive or flash media card does not disappear when the power is removed. This is different than for example the numbers displayed on the face of your calculator. When you turn off the power, they disappear. That’s because an electric current is required at all times to make the calculator remember what those numbers are. The calculator uses volatile memory. Non-volatile memory is designed for storing things that you need to use over and over again or that you need to be able to access for a long period of time.

Non-volatile memory is by definition, used for more important data storage. When a hard drive or flash media card fails, then, the data loss can be quite painful. Fortunately, because the device used non-volatile memory, the data is likely still there. It is just difficult to access, or more accurately, impossible for the average person to access. It is not, however, impossible for an expert with the right equipment and the right skills to access and copy the data that was stored on the damaged or defective drive.

Often when a hard drive fails, it is the index portion of the drive that is the problem. That means that the data that is lost or corrupted is only the data the computer uses to find the other information on the disk. In other words, the important stuff is probably still there, but the computer just can’t find it. Sometimes, the disk may be physically damaged and can’t be read properly.

Data recovery experts have special hardware and software that lets them extract stored data from these hard drives even if the index has been destroyed or the disk itself has been physically damaged. Not only that, but erasing data often only erases the index entry for the data and not the data itself. That allows data recovery services to restore data that has been inadvertently erased.

Of course, the most simple and foolproof method to make sure that your important data files are not lost is to make regular back up copies of all your files. For critical files, daily back up is highly recommended. A back up copy are just a second copy stored on another hard drive or some other storage medium such as a DVD-R or a CD-ROM. Making a back up copy is a simple and secure way to prevent data loss from hard drive failure or even accidental erasure.

Making back up copies is something anyone can do for little or no cost to protect themselves. If back up copies don’t exist, then the use of a good professional data recovery service can usually recover the lost information, but that service doesn’t come without cost.
