Your hard drive may fail due to various reasons (data deletion, virus attack, power surge, clicking noise coming out of your drive, head-crash, no sensation in the drive & many more). At Stellar, we categorize hard disk failure into three forms depending upon the condition of the hard drive.

Logical failure of the hard disk

The media is in working condition but some files/ data cannot be accessed for logical reasons such as accidental deletion/ formatting, lost partition or corruption due to virus infection. This situation is terms as logical failure.

Logical cum physical failure

In case if your hard disk gets detected by the system, but responds too slow either due to bad sectors or due to weak head in the disk, then it is terms as logical cum physical failure. Most of the time it has to be treated in CLASS 100 CLEAN ROOM.

Physical failure of the hard disk

In case if your hard disk makes unusual clicking/ knocking sound and doesn’t responds to your computer system (no sensation of the drive), either due to any mechanical component failure or electrical component failure, then it is terms as physical failure, which needs to be treated in CLASS 100 CLEAN ROOM only.

Stellar has proven capabilities to recover your important data from all these failures.

At Stellar, all physical disk recoveries are strictly performed only inside CLASS 100 CLEAN ROOM Labs.

What does it mean by CLASS 100 CLEAN ROOM?

CLASS 100 CLEAN ROOM is a controlled environment, necessary for opening the hard disk, which has less than 100 dust particles of size 0.5 microns or less per cubic foot of air as against a typical air conditioned office building containing 500000 to 1000000 particles (of size 0.5 microns or more) per cubic feet of air.


The only answer to this question is UTMOST POSSIBILITY OF DATA RECOVERY.

Damaged hard disk should never be opened in normal environment or by inexperienced technicians as it further increases the chances of hard disk being damaged beyond the scope of data recovery. Stellar is the only company in INDIA having CLASS 100 CLEAN ROOM for recovering data from all physically or logically cum physically failed hard disk.


  • Never open the hard drive and try hard disk data recovery on your own.
  • Data Recovery is a systematic scientific process and any mishandling can lead to permanent loss of data beyond recovery.
