One of the most common data recovery cases we have met is drives with a lot of bad sectors. How to repair and recover drives with a lot of bad sectors? The following information will help to understand fully about it.

Bad sectors in the hard drives are not deadly to your data but still dangerous. Some common or traditional data recovery software or tools can not handle bad sectors well and can only recover part and limited data.

Bad sectors are caused by:

* The integrity of the platter surface is failing
* Corruption by the track data
* Failing of a Read Write Head
* System Area Damage such as bad translation of the recorded medium

Location of bad sectors on a hard drive is very important as well, the master file table or MFT is normally located around LBA Logical Block Address 6,300,000, ofcourse you can find exactly where this starts using tools like winhex.

The Master File Table contains files names and physical location of all the data. A good example would to have imaged a hard drive but you had thousands of bad sectors in this area would mean  you would have raw data with no access to file names or location, such programs as raw recovery or fast file finders are good to use in these situations.

In all instances it can be difficult to establish which one of these problems is associated with your particular failure
As all of the above will behave the same way when it comes to trying to read data or even image a drive.

If one of the four heads in your hard drive fail’s and that head is not required for drive initiation for normal operation, the operating system would associate this as a bad sector or multiple bad sectors when trying to read (Very Common).

This is where diagnostics are needed to perform what i like to call Factual Prognoses
At first most if not all silent drives… meaning no clear clicking and appear to be spinning normally would associate with bad sectors

When it comes to data recovery, The following operations can make you understand the detailed faults:

* Checking of the Platter Surface
* Voltage Control of the Electronics
* Sector Reading with sector read analysis as in time it took to read a sector in milliseconds to disabling the Error read control to enable a bad read of a sector or even multiple comparison reads of a sector to get maximum results.
