DISASTER DATA RECOVERY

How to recover data in case of disaster

Our world is constantly at risk from manmade- and natural disasters. An increasingly important issue in our modern world is figuring out how to recover valuable data from damaged hard disk drives. The sense of helplessness we felt after the 2011 Tsunami in Japan is the source of our motivation to develop and distribute an “initial reaction guideline” for the correct recovery of data. Although the final phases in data recovery must be done at the hands of experts, taking the correct initial actions can make a huge difference in the end. DISASTER DATA RECOVERY will provide you with the necessary information for data recovery in case of disaster, and we intend to reach out to as many people as possible to help our society become more resilient.

This initial reaction guideline for DISASTER DATA RECOVERY is created and distributed by Dai Shigamoto with help from Professor Tani from Kansai University.

1.Water comes inside HDD

2.Dirt comes inside HDD

3.HDD falls down and gets stong shock

4.Chips on PCB are gone

Features of HDD which suffered from natural disaster

Normal Data Recovery Process is useless, because the damage level is extremely high. After Natural Disaster, HDD gets broken like this.

What is Disaster Data Recovery ?

AFTER Disaster

Recover Computer System

The most difficult problem for data recovery.
which had suffered from natural disaster, like
tsunami, river flood, storm, and earthquake.

BEFORE Disaster

Protect Computer System and get Ready

for a big scale crash.
Physical Damage caused by Software.
HDD Customization for Platter Damage.

Trying to clone data from non-accessible HDD by sector as much as possible.

Basically, parts replacement is the way for temporary repair.

100% clone is always preferrable, but the result depends on the damage type of HDD and the process of data recovery.

Replaceability with Donor Part

[ Head Stack Assembly ] Head Map, Capacity, Architecture Family, Microjog

[ Spindle Motor ] Seizure Problem, Lubricating oil

[ Printed Circuit Board ]Serial ROM, NV-RAM, Fuse, Resister, Diode, Capacitor, Coil, Microchip / pairment is also useful

If unique parts are corrupt, there is no way to recover data

[ Firmware ] Unique module, Non-unique module, Regeneratable module, Essential Module

[ Platter ] Bad Sector, Scratch, particules on surface

Data is recorded into
platters.
Replacement means nothing.

The Most Difficult problem is Platter Damage

For a long time, DR from scratched disk has been impossibleIf the Surface is partially damaged only, there must remain data at non-scratched zone,,,,,,,,,,
