Mr. OtheHill and MR Wanderer, Presently I am using that Hard drive In a newly assembled PC. Core 2 Quad, 4 gb RAM, 750 GB HDD as master and old ( faulty ) HDD as slave. This is essentially to save the data from other healthy partitions of the old drive. The disk managment data I posted above is taken before the new assembly. I do know whether and how I can act on the suggestions made by you. Raman V.R

If the old drive is functioning it should show in Disk Management just like the other one. All drives including USB drives should show in Disk Management. What is it you want to accomplish with the old drive? Simply to access the old drive? Does the old drive show up in My Computer? You do realize that the drive letters will be different don't you?

Mr OtheHill, Having assembled the new PC I have recovered the data from Partions D:, E:, and F: of the old HDD. Data from the partition C: of the old HDD is desired after which I can format the whole disk. Presently, the corresponding drive letters are different. Old C: is now I:. In vista I do not know how to get the present disk management data. Clicking 'Computer' shows ' Local Disk (I:) blank. Raman V.R Raman V.R

The method I described to get to disk management doesn't work? I don't use Vista but it shouldn't be any different than WinXP. Try going to disk management from Control Panel> manage> storage> disk management. I am somewhat in the dark here. Can you go to a run command from the Start button? If so, type cmd. You should have a C: with a bunch of other stuff behind it. Type I: and hit enter. You should have ONLY I: now. Type chkdsk and hit enter. That should run check disk and tell you if files exist on that partition. If files still reside there then the file system has been corrupted somehow. Post back with any results.

Mr. OtheHill, I swithced over to Win XP OS and did the Run>cmd> drive letter corresponding to the faulty one. I got the following message. " The volume does not contain recognised file system. Please make sure that all file system drivers are loaded and that the volume is not corrupted." Disk management window shows for the relevant drive Layout: Partition Type : Basic File system: Blank Status: Healthy ( Active ) Capacity: 9.77 GB Free Space: 9.77 GB % free: 100% Fault tolerance: No Overhead: 0% Raman V.R Raman V.R

There is a recovery tool called testdisk that may fix that partition. After downloading this free utility be sure to learn how to use it and apply it to the correct partition. The link below is a starting point. http://www.cgsecurity.org/wiki/Test...

I could not download the above SW. It says 'The compressed zip folder is either invalid or corrupted'. Raman V.R Raman V.R

The link below works as I downloaded from it. Get testdisk 6.11. http://www.cgsecurity.org/wiki/Test...

I downloaded Testdisk 6.11 on to my Vista Desktop. I am not able to open the file. Says '...Desktop\testdisk-6.11-WIP.winzip' is invalid. Raman.V.R Raman V.R

Raman You are correct. I did download the file but it is empty. Get the Ultimate Boot CD which contains testdisk, along with MANY other utilities. You make a CD using the file and boot to it. Because you will not be in the Windows environment when using this program you need to be able to identify the correct partition. That can be done based on the size. Write down the exact size and use that to find the correct partition when using testdisk. http://www.snapfiles.com/get/ultima...

Mr. OtheHill, TKU for your suggestions. I will Ultimate Boot CD and respond to you. As it involves burning a CD I may take some time. Raman V.R Raman V.R

Do you have a floppy drive in the computer in question?

No floppy drive in the newly assebled system. Raman V.R Raman V.R

Then you would need to burn a CD regardless. Ultimate Boot CD is a pretty nifty disk.
