datarecoverytools covers everything about data recovery !
Researchers at Georgia Tech Research Institute have developed a prototype that can totally destroy a hard disk, in seconds eliminating all the information. Dubbed as GuardDog, this disk erasure system uses, a 125-pound magnet that delivers a field comparable to the strength of a magnetic resonance imaging (MRI) machine. The system, fits inside a mini-fridge, consists an enclosed magnet with a slot big enough to accommodate a standard hard drive.
The new system differs from other commercially available disk erasers in its speed, size, and effectiveness.
Even alternative military-grade disk-destroying approaches must physically destroy the disk by grinding it into a powder to ensure complete destruction. Capability to erase drives completely could make GuardDog an effective system for the military, where a hard drive has to be destroyed at a moment's notice. Although GuardDog was driven by specific military applications, the technology would also benefit banks, credit-card companies, and other
organizations with sensitive personal information. The device not only removes the data, but also destroys the hard drive.
