TAIT Paathshaala on 19th July, 2016

TAIT Paathshaala organized its workshop for the exciting session on Data recovery on Tuesday 19th July, 2016 at Matunga Gymkhana, Matunga (E), Mumbai from 2:00 pm to 5 PM.

The session on Data recovery was conducted by MR. JATIN BOTADRA .An Electronic Engineer from Mumbai University and director at The CyberTech.

We all know how frustrating it is to switch on the computer one fine day and know that all your valuable data is lost / gone. It happens to us, our customer or someone we know.
Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible storage media when it cannot be accessed normally.

• Companies in India spend between Rs.10,000 and Rs.1,00,000 per year on data disaster.
• Nearly 70% of data loss is the result of human error.
• 60% of companies that lose their data will shut down within 6 month of loss.
• 240 hard drives crash in the city of Mumbai weekly.

YOUR RESPONSIBILITY

As IT engineers and service providers adopt mantra :
“It’s not a matter of if my hard drive fails but when?”

Hard disk drive
A non-volatile storage device that stores digitally.

HOW IT WORKS
A hard disk is a sealed unit containing a number of platters.

PLATTERS
Platters is a circular, metal disk that is mounted inside a hard drive. Several platters, a core made up of aluminium or glass subtract covered with a thin layer of ferric oxide or cobalt alloy on both sides of substrate material a thin coating is deposited by a special manufacturing technique. This thin coating were actual data is stored is media layer.

THE SUBSTRATE MATERIAL :

• Media layer
• Protective layer
• Platters

Tracks : Each platter is broken into 1000 of tightly packed concentric circles known as tracks.

Clusters : Sectors are often grouped together to form clusters.

HARD DISK LOGIC BOARD

Hard disk is made with an intelligent circuit board, integrated into the hard disk units. The read/write heads are linked to the logic board through a flexible ribbon cable.

ELECTRONIC FAILURE OR POWER SURGES

SYSTEM

• System BIOS will unable to detect the hard drive
• Hard drive could not be able to spin up.
• Sudden start up failure.

CONCLUSION

• Diagnosing and fixing a broken hard drive is serious business.
• Mr. Jignesh Joshi from Vidhi Computers said “It was an excellent session for System Integrators.“
• Mr. Ramesh Salunke from Parvati Computers said “I found the workshop interesting and knowledge oriented.”
