unable to delete old system files

[flashassassin]

ive had to replace my motherboard and reinstall windows.
my hard drive was originally split into 4 partitions.
the old xp installation was on C.
when i reinstalled windows it wouldnt let me format the old system drive so i installed onto another partition. this was automatically renamed to C.
everything works fine except i have this useless partition (now drive D) which it wont let me delete or format because i dont have admin rights on it. i have tried changing permissions ect but still no go.

is there a way i can wipe this partition?
thanks

i have tried that. i have managed to get rid of some files but most still wont let me. is there any other way? i thought i read somewhere that there is a program that would do this?
