How data recovery is performed by data recovery experts
There are two types of hard drive issues that may prevent you from accessing your data:
Software and hardware
Software issues include accidental file deletion, hard drive formatting, corrupted file system, partition deleted etc.
Hardware issues include drives making clicking or hissing noises, hard drive damaged because of a power surge, water damage. External drives fail due to accidental drop, mishandled and so on.
What you should expect when you take your drive to a data recovery company?
Data recovery specialist will normally start by performing a diagnostic on the failing hard drive to identify the damage and failing component. The diagnostic helps the technicians and engineer to identify the proper method to be used to recover the lost data.
Software data recovery process
When the customers approve the data recovery, the data recovery specialist starts by making a clone or replica of the damaged hard drive on to a new one, then the recovery will be completed on the copy (new drive) This process insures that the source stays intact.
Data recovery is a very delicate process; the failing drive should not be forced and must be accessed with the appropriate tools preventing any additional damage.
The data recovery specialist completes the data recovery process on the cloned hard drive by using specialized data recovery software. The process of the data recovery can be very lengthy analyzing and reconstructing all data specs on the hard drive. This process can take from one day to several days. In rare situation can take weeks depending on the storage size of the hard drive and the severity damage on the source.
When the source is severely damaged (shredded) the files recovered may be useless. How the data does become shredded? Data becomes shredded when the magnetic read/write head is damaged and the hard drive is forced by standard computer repair shops using third party tools to read the data off the surface in the process the data is being modified by adding additional bits to the stored content.
Data successfully recovered is transferred and stored on to a new media, such as a new hard drive, flash drives, or even an optical disk depending on the amount of data.
Hardware Data Recovery
Hard drive with hardware or mechanical issues requires a more special treatment during the data recovery process.
As a normal procedure of data recovery at companies like Netcontrol Disk Laboratory, the drive is assessed through a diagnostic. The diagnostic determines how the drive will be handling for the recovery.
Hard drives with hardware issues such as crashed heads, ceased motors and other mechanical components; the hard drive is submitted to the clean room. A class 100 clean room is a conditioned room with particle free where hard drives are disassembled and replace any failing component from a identical donor. Disassembling a hard drive for data recovery is super special process; one may consider this process as a brain surgery.
However as of this writing I am not aware of any brain transplant, maybe it can't be compared. Hard drive in a data recovery room, magnetic read heads are transplanted, disk platters are exchanged into new disk donors, motors are replaced in special circumstances. This data recovery process allows the data recovery engineer to resurrect a technically dead hard drive and bring it to life for a cloning process.
The hard drives submitted into the clean room require identical drive as donors, therefore the older the source drive is; it becomes more difficult to locate the donors. What makes this more difficult to locate a donor is that computer hard drive supplies don't ever list the details of the hard drive; details such as the series date of manufacturing or firmware.
The drives donors when submitted to the clean rooms are destroyed in the process, and the reason for this data recovery operation is taken place in a class 100 clean room is to protect the disk platters and magnetic read/write heads. This data recovery process can't be performed in any other place a normal conditioned office room is full of dust and particles, if a hard drive is opened in a standard office space; even the smallest particle of dust underneath the magnetic read /write head can cause the heads to scratch the entire surface of the disk platters.
A class 100 clean room for hard drive data recovery is equipped with special tools, equipment and of course the right engineers with the experience to perform such operation of data recovery on mechanical damaged hard drives.
When the transplant of parts from donors to the patient drive is completed, the hard drive then is assigned to another data recovery specialist who will perform a software based recovery, such as start a new cloning process and so on.
What is the success rate of data recovery in a clean room? A success rate of data recovery in a clean room is about 80% of catastrophic data loss. When a hard drive is submitted to the clean room, the data loss is already catastrophic. According to engineers about 20 % of hard drives severely damaged that goes to the clean room may not be successful. This is situations when the surface platters present damages of scratches caused by the disk actuator arm. And other circumstances where there are electrical discharges delivered directly to the disk platter; this also includes when other inexperienced technicians have previously manipulated the hard drives.
