Data Recovery Solutions For Valuable Digitally Stored Information
No matter how advanced digital storage systems are nowadays, data failure can still occur and data recovery is the best solution to recover every piece of stored information or even just to salvage a portion of it. Data failure can occur in the form of:
- Logical Damage - data recovery processes involve software-level solutions.
- Physical Damage - recovery may require advanced forensic applications beyond the software level in order to deal appropriately with the physical damage.
The Science of Data Recovery
The processes involved in the recovery process of digital information are very systematic that data recovery relies much on computer science. At the broadest sense used within the context of modern-day computers and related electronics, data recovery is simply the process of extracting useful digital information from physical storage systems such as hard disks in desktop computers or laptops. With solid state drives gradually replacing the position of hard disk drives in the computer market, this storage system is also of particular interest among data recovery software developers.
The Processes Involved in Data Recovery
Most commonly, data failure is attributed to the operating system running the machine. In which case, the file system is said to have logical damage and hence cannot be accessed by the host OS. Since the OS itself cannot access the drive, repairing at the OS level is therefore impossible. Thus, technicians resort to the bootable OS that runs entirely from the memory and does not require the use of the damaged hard disk drive. The bootable OS can fully run within the limits of the memory resource due to its tiny memory footprint.
Once the damaged hard drive is accessed through the bootable OS, migrating recoverable data follows. Backup media for storing recovered data include writable compact discs and flash drives. For larger data files, external hard drives are also of common use. After data files are copied to another medium, the damaged storage drive can be reformatted so that logical errors are fixed and the medium can be used again just like new, that is, if errors occur only at the logical and not on the physical system.
Popular Data Recovery Solutions
For damaged hard drives inaccessible by the OS, solutions revolve around the use of bootable OS with a set of repair tools. These packages are delivered into the system in the form of a boot disk or a Live CD or USB. For data recovery involving external storage media such as SD cards and USB flash drives, file recovery solutions running at the OS level of the machine are employed.
A boot drive failure followed by a restore failure in Windows backup (thank you Mr Gates) seriously compromised the Chorus’ planning for the forthcoming Mozart choral concert in Sheffield City Hall. Data recovery took just three days and my blood pressure returned to normal. Thanks again Andy
