Help me….my hard disk is damaged!!!

Hi everyone , I am employed as a manager in a firm. I have a problem that I had like to talk about. My system was working fine the other day, but while copying a file by nero….the system hanged and I had to restart it. But I got a disk boot failure error. Then , I tried to run a windows xp installation CD, but that is also showing some error message during installation and the installation fails.I did check the bios settings and the disk fails to show…and had it checked on another system also…but bios cannot detect the hard disk.I think the disk is damaged or something like that.The disk has important data from my company’s point of view…..that I need to recover.
Please let me know if there are any ways to get my data back from this disk!!!!

 

If it is a Western Digital and it goes click-click-click when you turn it on, data used internally by the drive has been corrupted and your only hope is a COMPETENT recovery service. DriveSavers will want about $4,000 to do it. I found a company in England that only wanted $800 and the stuff necessary to do it myself; but, haven't had enough of that business to justify $13,000 for the capability.
If the drive is not a WD, there is a reasonable chance for far less effort. ($)
It is hard to troubleshoot, sight unseen and without any particulars; but, here goes....
You need to have a working drive of the same or slightly larger capacity and a program to "clone" a hard drive by copying every sector, one at a time. I use WinHex because it gives me a list of the bad sectors when it is done.
These need to be in place on a system which boots to its own (3rd) drive and has a spare location to connect the bad drive.
Freezing the drive (sealed tightly in a Ziploc bag) for over 4 hours improves the magnetic fields on the media and will often do the trick to allow access; but, the drive needs to be placed on something which will absorb any condensation due to the freezing.
If it is recognized, clone it as fast as you can and then get your files off of the copy.
If it is not, the next step is to purchase an absolutely identical drive so you can swap the logic PCA. EBay is a good source though you need to match all of the details on the drive's sticker; the same model is not close enough.
There are hundreds of other tricks which depend on the make and model of the bad drive; but, one major caveat is crucial. Don't let anybody do anything that might write on the drive. CHKDSK, Spinright, Norton, and several other utilities are too often used and recovering the data after they made a bigger mess is much harder.
