Hard Disk not detected

I have a 500GB Hard Disk. When i formatted it once, I got a warning telling that do not install the OS in this drive or you might loose data. But I had to install it there. No problem occurred after that for a few days, but one day the computer just hanged at start up.

Problem:

First time when I power on the system and start the computer, the hard disk is read in the boot menu but it hangs at Starting Windows. Without switching off main supply, when I restart the computer, the hard disk is not read under the boot menu.

When I plug the same hard disk in a later version of mother board i.e in another computer, each time on Starting Windows I get a Blue Screen. The problem is corrupt OS according to the code that appeared on the Blue Screen.

How to retrieve the data from the hard disk?
Please HELP !

When I start the computer from the off condition the hard drive is read once, but after restarting on hanging it is not detected. For it to appear under boot menu I will have to shut down the power and switch it on again. But it just hangs on starting windows.

I also tried to master slave from another computer. I mastered the working hard disk in the other computer and tried to boot in that hard drive. But the result would be a hang at starting windows again. I removed the not working hard disk and tried to boot in the working hard drive then it would boot.

Result:

Plugging this not working hard drive and setting that as a slave does not work. It just hangs at starting windows again.

No I meant starting windows from the working hard drive in another computer with my NOT WORKING HARD DRIVE plugged in does not boot. The computer just hangs in starting windows.

As I have said before, the problem shown by the blue screen is OS Corruption. How to fix this while my hard drive cannot be read at all?

Yes of course I can hear the drive spinning, but no clicking sound.

Did you try starting Windows in Safe Mode? (F8)

Do you have a repair disk?

Hey there,

If I plug in my external harddrive, seagate 1TB, it does connect or at least the sound is heard when it connects. After a few seconds the sound is heard that it is disconnected. In the meantime it is not able to acces it for the simple reason that it does not show up, also not in drive management. Can someone please help me?

thank you already
