There are a lot of different ways that hard drives can lose data, from physical issues in which the sensitive internal components break down to logical issues in which file system metadata becomes damaged or unreadable. Even disconnecting an external hard drive from your computer without safely ejecting it first can result in data loss! To recover lost files, sometimes it can take a whole lot of work.

Recover Lost Files in Logical Data Loss Situations
Hard drives use a set of logical rules to organize data. When these rules break down, your computer loses its “map” of where data lives and becomes unable to find it. This happens when you delete data, or reformat a hard disk. Logical failure also happens when important file system metadata such as the boot sector or partition table become corrupted or damaged.
In logical data loss situations, data recovery software tools often help users to recover lost files. However, most widely-available software tools have their limitations. The dicier the situation and the more logical damage the drive has received, the more difficulty they have turning up usable data. Furthermore, if improperly used, data recovery software can cause more problems than it solves.
When it comes to logical data loss situations, such as file deletion, accidental reformats, or file system corruption, it is sometimes better to leave data retrieval to the professionals. To recover lost files with a high degree of success, Gillware’s expertly-trained specialists use powerful data recovery software tools of our own design.
Recover Lost Files in Physical Data Loss Situations
When a hard drive breaks down, it takes specialists in the field of hard drive repair to recover lost files from it. Since their invention in the 1950s by IBM, hard disk drives have been incredibly complex pieces of technology. And since then, they’ve only become more complex.
The sensitive components inside your hard drive has razor-thin margins of error. Hard drives are well-designed enough to keep working for years and years with all this machinery inside them. But it doesn’t take much to break those components down and cause data loss. When this happens, hard drives can stop spinning up. They can make clicking, beeping, whining, screeching, or grinding noises as well. These signs indicate a kind of severe failure that almost always requires a trip to a professional data recovery lab.
When those components break down, it takes a lot of hard, careful work to repair them. The innards of a hard drive are extremely sensitive to dust and other outside contaminants. A single grain of dust on a hard disk platter surface can mangle a set of read/write heads and cause some irreversible data loss. To recover lost files from broken hard drives, skilled engineers must open them up and replace their failed parts inside a clean room data recovery lab.
Repairing a broken hard drive can involve replacing broken read/write heads or a shorted control board. Hard disk drives with scratched disk platters must be polished with specially-designed burnishing tools. Hard drives in critical condition often require multiple rounds of repairs before the engineers can recover lost files from them.
