We've all been using computers for a while now and I bet none of us have been spared from at least one data loss related problem in our technical "career". Data is so in fact losable that you're approximately forced to make backups for everything you have, for distinct safety reasons. Data loss can occur due to several reasons, including:
- corporeal damage - when your data warehouse unit gets physically damaged, data recovery is often difficult. corporeal damage can translate into a badly scratched Cd or Dvd containing critical data, a failing hard disk head or motor and so forth. corporeal damage can be avoided, but you can never in fact safe yourself from it 100%. A hard disk for example, can break down due to aging, constant workload and so forth. Cds and Dvds aren't fully protected even if you keep them in the cleanest, scratch-free conditions possible.
Harddisk Data Recovery
- Logical damage - logical data damage takes place at file buildings level as opposed to corporeal level. Logical damage is more common, as it can be caused by numerous supplementary factors such as power outages, system crashes, driver problems, Raid controller issues and so forth.
- Human error - human error factors consist of everything from "oops, I accidentally pressed delete" to overwriting files, captivating them around, formatting over critical files and so forth. Basically, of the three types of data loss causes, human error ones are the easiest to avoid and yet they are the most common, because of the users' low computer skills, impatience or forgetfulness.
Sure, if you're a straightforward user that lost some important data, you won't in fact be curious in knowing Why you lost it, but rather if you can get it back. Still, data recovery may often depend on the "Why you lost it" factor. And unfortunately, in some rare cases, data recovery becomes impossible and the most common of data loss categories is the corporeal damage one.
If your hard disk blows up on you, there's in fact nothing to be done about it and no specialized data recovery schedule or data recovery professional will be able to help you out. But not all hardware (physical) problems fall into this category. For example, a hard disk with a failing motor still holds a chance for data recovery, whereas if the section that holds the logical data gets burnt out or magnetized, you most likely have no chance of getting anything back. Some corporeal problems may be partially fixed, with only a part of the data being recovered. Although this is never a think to cheer for, you can at least scavenge up some of your lost data.
The easiest type of data loss to recover is, fortunately, the one falling under the human error category (fortunately - because this is also the most common). When you delete a file from your operating system, it won't show up in the file buildings anymore, but that doesn't mean it's gone forever. What the operating system does, is store away that file on a definite sector of your hard disk, where it is held for sake keeping. The only way you can truly delete these files is by overwriting that sector with new data, over and over again. That's why time is an important factor when it comes to data recovery. If you deleted a file yesterday for example, chances are that your system didn't overwrite it with anything else in that "safe closet" on your hard disk. However, if you deleted it last year and subsequently deleted, overwritten and moved files colse to your hard disk since then, chances are data recovery becomes impossible.
