WAY OF RECOVER DATA FORM HARD DISK.
Your hard drive just stopped
working. It never made any odd sounds like screeching, popping, or clicking,
and it didn't crash. It just quit and it has some priceless data that isn't
backed up to another device. This guide may help you troubleshoot and correct
any problems related to your drive. (Alternatively, read up on how to recover data from the hard drive of a dead laptop.)
Be sure to read all warnings before proceeding.
Inspect the outside of the
hard drive for damage.
Stop using your computer or
external hard drive.
Power down the computer or disconnect
the external drive.
Remove the hard drive from the
computer or device.
Examine it carefully for 'hot
spots' or other damage on the external controller board.
Check if there are broken parts.
Replace the cables. Plug the hard drive in with new cables (power and
data connection) that you know works and try again. Note that an IDE drive will
need a flat-ribbon cable.
If you have a PATA (IDE/EIDE)
drive, switch drive pin settings.
If it was “slave” or “cable
select,” set it to “master.”
Plug it in alone without any
other device on that port and try again.
Try other IDs and/or another
PCI controller and try again. If you
don't have another controller, a PCI card that adds ports to your computer,
just change the ID.
Plug it into an external
drive adapter or external drive case (i.e.
USB) if you have one.
If it does not spin up, try
connecting it to another power source (include data connection as some drives
don't spin up without). If on both it does not spin up, the fault is most
likely related to the Printed Circuit Board.
Connect the drive into
another computer and try again. If
this works, it is possible that the motherboard is at fault and not your hard
disk.
Method 2:
Replace the Drive's Controller Board
1 Inspect the drive's
controller board carefully to see if it can be removed without exposing the
drive's platters. Most drives will have an externally-mounted controller
board. If not, stop here.
2 Find a sacrificial drive.
It is important to match the exact same model number and stepping (i.e.
firmware revision, printed circuit board number). Matching drives can sometimes
be found at places like eBay, inspect the photo in the auction carefully to
determine if the model and firmware match. Contact the seller to be sure the
drive being auctioned matches the picture prior to buying.
3 Remove the controller board of the failing
drive.
Remove the screws with the
correct screwdrivers. Most drives use Torx (star drive) head which is available
at home repair stores. Be careful, the screws are soft.
Learn everything about how it is
connected to the drive. Most drives are connected via ribbon cables and pin
rows. Be gentle. Do not crimp or damage the connectors.
4 Remove the controller board from the
working drive. Again, be extremely careful.
5 Attach the working board to
the failing drive.
6 Connect the drive to your computer or
device and test. If it works, immediately copy your data onto another form
of media or a different hard disk drive. If that didn't work, try to
re-assemble the sacrificial drive with the working controller board. It should
still work.
