HDD volume - unkown in device manager


I’m helping a friend who had a computer crash. He desperately needs the files on in. I took his HDD (Western Digital Caviar 250 GB) and plugged it into my PC internally at an IDE slot. Regardless of how I set the jumper on it my PC would not load the OS from MY drive. However I could see the WD HDD had been detected and identified in BIOS. I tried starting my PC in safe mode, but it got stuck when loading MUP.sys – indicating HDD problems. So I took the WD HDD and connected it with an external HDD adapter kit, so it is now plugged in externally via USB with external power adapter. My PC starts fine again. The external WD HDD is detected and displayed in the device manager, but nowhere else, not in system management or disk management, my computer etc. When looking at it closer in the device manager, under the Volume tab, it is not recognized.
Has anyone heard of this problem? Is the disk just so damaged that it needs to be restored professionally? It can communicate enough to be detected and recognized as a Western Digital by my PC, but it ends there. Could this have something to do with a broken MBR?

Please advice me on how to recover the data!

  1. Does BIOS detect the drive with its correct model number and full capacity?
  2. I don’t know how this problem accidently got posted twice, but I have another thread with it too. Anyway, yes when I plugged it internally with the IDE cable it was shown in BIOS and recognized as a Western, but I could not get the PC to boot up from MY HDD when I had the WD HDD plugged in so I was forced to unplug it to star my PC.
