Cannot delete folder : Access is denied

i used partition magic to merge 2 partitions and a folder has been created. i cannot delete the folder but i can access it. i have read this thread and followed the instruction but still can't make it. might be something wrong at somewhere.

the error that i got is

Cannot delete System Volume Information: Access is denied.

Make sure the disk is not full or write protected and that the file is nor currently in use.

FYI, i am logging as an administrator since i am the only user of this computer. the folder name is 'merge'.

Properties of this folder:

Administrator : full control
Everyone : read

at the Advance Secutiry Setting for merge
Administrator has full control while Everyone only has several Read options that has been ticked.

[solved]

ok, i've done it. just follow instruction from miscrosoft website.

I have the EXACT same problem.
How did you fix it?
