If all else fails you can try this...here is a tutorial i wrote a while back and has a 50/50 chance of working. In my case it worked just fine..

Before you go and spend (some quotes) $1000 for HDD data retrieval,you could try this..!
First you can try this.... Hard Drive Diagnostics...
http://www.carrona.org/hddiag.html to give you more info on what's wrong with your HDD...
NOTE: In the end you have a 50-50 chance this will work.. Also this procedure is not for a SSD...!
After some research and some verification from 2 very knowledgeable PC tech's,i tried this.. Remember patience is key here....
That click you hear is the read head snapping back to the rest position. If you get unlucky, there is a mechanical failure. The freeze may bind the arm long enough to grab data, even if just a few MB at a time. The drive will heat up quickly. If the actuator is not faulting at the controller board this may work..
Now to the procedure.....
Put the HDD into a Deep freezer ( temp needs to be at least at 0-F to -40F) for 24 hours,then when it is ready have a USB adapter ready to go and your back disk/HDD as well,one ice pack and towel.. (Be Quick) wrapped the HDD with towel with ice pack (have HDD in question powered up). Then you may have to wait a hour for the HDD to warm up to work.. After about a hour or 2 take towel and ice pack off and if all possible place an external fan for more cooling or get a fresh ice pack to cool it right back down.. During this time you should be transferring data.
NOTE: It has been mentioned you could use dry ice to cool down/ freeze your HDD until time to retrieve your data..
Important info:
I suppose an external sata connection would work and the fan came into play because the ice pack had thawed out after 2 hours.. Also for faster data transfer i just use move or send to than copy when i could. You may have to create a file (under a different name) for some data if you have more than one profile like i did.. A note here you may get a error will not initialize or MBR is not working this may be because the HDD is still to cold,which i got trying to use it straight out of the freezer. Just keep trying until the HDD starts working.. I could have bought a new actuator board for the HDD but it was as much as a new HDD and not guarantee to work..
NOTE: Obviously if your HDD has external damage or severely damaged in other ways this method may not work at all!
And quote:
The BEST method is to use the mfgr provided boot CD. There should be a clone feature there.
Known issue:
The mfgr's are consolidating, so it can be a challenge to locate the proper CD.
Also, cloning will copy over file system (logical) errors. These are what MS chkdsk resolves. MS chkdsk is NOT a physical repair tool. Run chkdsk on new drive after cloning. The old drive probably corrupted the file system.
NEVER run chkdsk on a drive suspected of physical failure.
Reminder:
Every hard drive, factory new, contains physical errors. Every hard drive has a tolerance value for these bad sectors. These are controlled/managed in the drive's firmware and Windows CANNOT see them. Bad sectors are visible to Windows only after the tolerance is exceeded.
