HDD hard drive bad sector repair
Bad sectors on hard drive in most cases can still be read
What is a bad sector?
Bad sectors range from physical damage of the platter to faulty or failing read write heads... to a sector failing the ECC error checking control checksum

Please: Evaluate this site Before attempting any form of self data recovery or hard drive repair
What is the problem?
Does the hard drive spin?
If so does it click?
Does the armature kick out?
Do the hard drives heads vibrate to initiate?
Is there an odd smell to the drive?
If it doesn't spin do you here a slight or faint ticking sound?
Does the BIOS see the hard drive?
Does the BIOS see the hard drive as the correct model?
Are there funny characters showing on boot?
Does the operating system blue screen?
Important things you should be aware of before you do anything to a suspected failed hard drive
Static discharge will kill a hard drive when handling... especially the internal components
Dust will destroy your data... DO NOT OPEN! In my experience I see so many hard drives destroyed by helpful neighbors when the problem was not situated internal of the hard drive assembly. Just because it clicks doesn't always represent an internal failure.
Swapping the electronics runs the risk of further damage, especially if the revision number of the PCB is different.
You will have a greater success of data recovery with less risk if the original electronics is repaired.

Bad sectors on a hard drive what does this really mean
Bad sectors are cause by several problems, One being 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 of course 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 several operations can give you clear understand of the fault at hand
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
Remember that drive with bad sectors are failing and will worsen with more use no matter the fault
Its a good idea if data is important to call the professionals and get a fair quote
