Software Applications For Hard Disk Data Recovery


Software Applications For Hard Disk Data Recovery

Wide range of software applications have been designed as data recovery programs that well suit your needs.
In-depth scanning of your storage device may help you recover data.

A defined cluster size is used to manage data and while formatting the disk, partitions are elaborated in terms of clusters. Moreover, the cluster size can also be customized with the availability of third party tools. Thus, it is recommended that before using any third party tools, backup of all-important data should be taken as the process may cause some data loss.

Example:

You received an error message “A Disk read error occurred Press Ctrl Alt Del to restart” or your stored data is inaccessible.

Source of data loss: This error can occur due to a fault in MBR (Master Boot Record), which is accountable for loading of the OS.
Recovery: The Window installation CD/DVD is required to resolve the error. So, in order to repair MBR, the command ‘Fixmbr’ from the installation CD will run at the command prompt. If in case, ‘fixmbr’ fails to repair, hard disk needs to be reformatted.

Best Data Recovery From Logical (Non-Hardware) Damage


Best Data Recovery From Logical (Non-Hardware) Damage

Overwritten Data
With the use of Scanning transmission electron microscopy, data can be overwritten on a hard disk. Peter Gutmann introduced this method in 1996. Later on, in 2001, Gutmann and Colin Plumb further improved on the “Gutmann method”, which is now used by disk scrubbing software packages.

Corrupt Filesystems
Due to damage in the filesystems, hard drive data is unreadable. In this case, damaged filesystem can be repaired for recovering a portion of the original data. No special physical equipment is required in this process and thus, it can be performed by an unskilled user.

Online Data Recovery
Deleted data can be restored through online data recovery. This recovery process is executed by a recovery technician who is not the vicnity of the affected PC but still accesses it from another location. It is a convenient and user-friendly technique that requires a stable broadband Internet connection.

Easy data Recovery After Physical Damage


Easy data Recovery After Physical Damage

Physical damage of the computers and the data storage devices always causes some data loss. There are several reasons for physical damage that may include tapes breakage, dye layer scratched off or metallic substrate on CD-ROMs, head crashes and failed motors etc.

Recovery Techniques
Multiple techniques are involved for physical data recovery including:
  • Restoring data in the hard disk
  • Disk-imaging procedure for recovering readable bit from the surface
Hardware Repair
  • Deleting a damaged PCB (printed circuit board) and using matching PCB for restoring it.
  • Hard disk platters are removed from damaged drive and installed into a healthy drive.
