plz sir do me a favour .. tell me how i use it.. test disk software.

First, please uninstall Partition Magic. It is no use to you on a computer running Vista or Windows 7.
About the TestDisk program...
First download the version of TestDisk for Windows:
http://www.cgsecurity.org/testdisk-6.11.3.win.zip
Save that downloaded zip file somewhere you can find it, maybe on your desktop.
When it has finished downloading, go to the desktop (or the folder you saved it in using Windows Explorer).
Right click testdisk-6.11.3.win.zip and extract it. In the new folder that makes, double click TestDisk.exe to run the program.
This page has full instructions for how to use the program:
TestDisk Step By Step - CGSecurity
To simplify what it says...
Every page has a menu. Use the up and down arrow keys to highlight the right menu choice, then press Enter, and it will go to the next step.
On the first screen, use the up/down arrow keys to highlight "Create" for the new logfile, then press Enter.
On the next screen, you pick which hard disk to work on.
That's easy if you only have one hard disk :)
Pick the right disk and press Enter
Next you see a list of the different types of partition table.
Yours is Intel/PC so select that and press Enter
Then it shows a list of partitions which are in the partition table. Maybe it will only show your C: partition. If your D: partition is not in the table, we shall fix that later.
Select Analyze in the menu and press Enter
In the result of Analyze, maybe it will only see one partition (C)
so select Quick Search and press Enter
Now it shows you what it found on the disk.
If that list makes sense (it shows both partitions now, and the sizes are correct) select Write and Press Enter. Then it will make a new correct partition table for those partitions. Then you can leave the program.
If you don't understand the list, and you are not sure it is correct, do not select Write. Select Quit instead; then it will not change the disk (you don't want to make the wrong changes)
After you have fixed the partition table, you will need to reboot the PC before Windows can use your D: drive.
