Hard Disk Recovery
The loss of crucial files and information due to a hard drive failure can be a real catastrophe for both individuals and businesses alike. Preventive measures such as the regular backup of hard drive contents is the best answer to this problem, but these preventive measures are not always taken. The result is very tough situations where a critical file is badly needed, but has become inaccessible due to a hard drive failure or software problem. This is a problematic situation that demands a fast and reliable solution. Depending on the cause of the failure, this may or may not be possible.
User created problems are the easiest to solve. When a user accidentally deletes a file, that information has not actually been deleted in the sense that most users believe. Instead, the file has been marked for overwriting, meaning that the operating system now views it as potential space for new files and information. Until that space is needed, the deleted file will sit dormant and untouched. With a free utility like TestDisk, users can regain access to such deleted files in short order. TestDisk is a comprehensive piece of software, and best of all, operates at no charge. As an open source project, TestDisk is both free and highly reliable. Using TestDisk can solve most hard drive and user failure issues without too much trouble.
Software related problems are somewhat more serious, but still within the realm of recovery. When a drive partition is damaged or corrupted, it makes the entire drive inaccessible. This can make it appear as though the drive has failed completely, when in reality the majority of the files remain perfectly intact. A powerful utility like TestDisk, however, can scan existing files to rebuild a partition that an operating system can then use. Corruption is a real concern in hard drives, often causing malfunctions that affect the entire system. TestDisk and other file utilities can reverse the affects of this damage to the system.
Hard disk recover utilities like TestDisk and Undelete Plus are very much capable of handling both user and software issues. When a bigger problem is at fault, however, professional help may be required. Hardware failures typically count as a bigger problem, rendering even powerful utilities like TestDisk unable to help. Hardware failures include burnt out read/write heads and bad logic circuits. These problems are hard to fix from home, and can lead to more permanent data loss. A burnt out motor can cause the read/write head to drag along the magnetic platter, destroying data as it does so. This kind of damage is irreversable, but portions of the damaged disk can yield segments of intact data.
For hardware problems, services such as DriveSavers must usually be called in to help. These services are expensive, but can usually promise at least some data recovery even in the most difficult circumstances.
