I so need your help now. I have two partitions and one is corrupted. See the image below.
First of all, i am using windows XP pro Version 2002 Service Pack 2. Here's what i did. This is an external HDD within an enclosure. I attached it to my friend's computer and created some Permissions under the Security options. I kind of messed up doing it (the permissions) because all of the subfolders are also "Access Denied".

This is a 300 GB HDD. I even tried the chkdsk /r and chkdsk /r/f using the windows xp pro CD, it did not fix the problem.
