Hi All
one of my systems got virus and needs to be formatted. I did using boot disk of xp os. I selected "c" particion and did. after I am able to find out some part of "d" drive also formatted . I dont understand why it happend. Please let me know .

Ok I don't understand well what you mentioned before...

You have formatted you drive C with a new installation and then you see that D also was formatted. Is that what you say?

If yes then this may be an error that you click on and format the partition D as normally it should only format the one you have chosen.

part of "D" drive got formatted. I am sure that I have selected "c"

If you're not sure then you may have selected Drive D too!!! Have you lost important files with this mistakes?
