Hard Drive Data Recovery Facts

You have probably had to endure at some stage of your life the subtle foreign babble that many people tend to speak that are involved in technical employment and the data recovery services industry is no different

The times when we find ourselves at the receiving end of this technical glibness is when we are actually in need of a service so come on guys, get customer focussed and start talking in plain and understandable language.

Not picking on any camp in particular as most technical sectors have there own techno babble, but lets look at terms often used by data recovery companies.

When you have a data recovery problem the chances are that your problem will be described as one of two different types and these are logical problems and physical and physical problems, although to add to the confusion there are some grey areas where the two overlap.

Physical problems are as the term describes physical issues with either your drive or your storage media, and these are also often referred to as mechanical failures. Mechanical failures are often subject to hard drive repair which should be carried out in a special antistatic and dust free environment called a clean room (always check to see if the data recovery company has one).

Just as with any mechanical device if you keep on using it further damage can occur for example inside a hard drive is a reading/ writing arm (called read/write heads). If this comes into contact with the internal spinning drive (head crash) it creates debris which then causes further crashes and in extreme cases this cycle continues until the platter is destroyed beyond repair.

Logical problems tend to revolve around file loss or damage of some description and generally this is not as serious (or as costly) to recover although this may not be the case if somebody has made a bodged data recovery attempt. Generally the files and folders are still on the drive (even if they have been deleted or the drive has been formatted) somewhere but they can’t be seen or perhaps simply can’t be read as they may have become corrupted (file corruption) in some way.

(One common problem that can manifest itself and is often a source of data loss is hard drive degradation, in simplistic terms this is where parts of the drive have simply lost the ability to be either written to or read from. The data on the drive may still be recoverable but it is just difficult to “see” so needs to be read using specialist tools. ~Physical problems such as hard drive or media degradation can cause file level problems as well especially in the warmer months of the year when computers are prone to overheating. Drive degradation is when the platters magnetic surface as the phrase says “degrades” making it difficult to either store further data or read existing data on the disk. Data can still be rescued though by recovery professionals.}

Other logical failures if you want to learn more include for example lost files and folder, virus attacks causing damage to system files making it impossible to access data, destroyed file tables, corrupted files, bad MFT records possibly caused by boot sector viruses, partition errors, and the operating system not being able to access the drive in order for you to actually use the computer.
