Different pieces of information may be lost when a computer system fails. The system fails as a result of a number of attacks. The attacks may occur when a system get infected by various malicious programs. This corrupts the disk storage applications leading to loss of information in such locations. Data recovery activities are aimed at salvaging the information in the corrupted disk segments. A number of approaches may be used in such a case.

A computer system is made up of software and hardware elements. These are interlinked by communication channels which are transferring the pieces from one location to another. The flow of data between the various tangible elements is done by the use of information buses. The software applications initiate the processing operations by issuing a series of commands. The commands direct the hardware components on the operation to initiate.

The operating system is the main application within a computer system. It controls all the running applications and defines the memory allocation for each of these programs. It offers a communication interface between the hardware, software and the end-users. The interfaces ensure that there is a good flow of information between different points. The memory allocation ensures that there is no conflict in running of different applications.

Conflicting instruction may be sometimes issued. This happens when the same memory segment is allocated to a number of computer elements. This result in freezing of applications may cause a failure in the storage locations if it is severe. Malicious applications may also launch an attack on the main memory. This corrupts the memory. A series of harmful instruction may be given to storage locations such that a failure may also occur. This ends up corrupting the information stored here.

Program installation procedures are very critical. The main and key files are installed first. This is done sequentially in way that allows for a disk processes. The rest of program files are installed afterwards. Execution is also done sequentially. Large disks are critical in information recovery. The main disks holds data being processed after which it is transferred to external locations.

Partitioning of the primary and secondary storage locations may be very important. This is done through a number of fragmentation operations. The memories are divided into a number of segments which are accessed differently. Disk fragmentation boosts the memory management operations. In an event that one collapses, the information in other disks is not affected.

The level of attacks by the malicious applications on the main memory differs depending on the type. A mild attack slows down the operations of storing and retrieving the information. This gives time for the data to be backed up. A severe attack may completely damage the storage locations such that the information gets lost completely. Some processes launched may allow for some of information to be transferred to a number of external locations.

A number of forceful booting operations are used in the data recovery processes. The severely damaged disks may be subjected to forceful booting operations. As the disks slowly boot, the critical files are transferred from the corrupted locations to external locations.
