Download a util from the MS / windows2000 site called 'xcacls'. It allows you to modify permissions from the command line. Use the /? switch to work out how to use the command, give your user the permissions you need
Or you could just right click on the directory, click on the Security tab, select the Add button, enter your userID (or the Admin's user ID, or who ever happens to be the owner of the directory, assuming your an admin), then give this new ID full control, and viola, full access! Now delete the directory and reboot, and then let us know if your system still works! :-)
Just kidding there, don't delete anything, in fact, don't even give yourself permission to look at it. The fact that even admins don't have access to this should be a good indicator all on it's own.
As an aside, I just converted two partitions from FAT32 to NTFS, and when it created that System Volume Information directories it gave them inherited permissions, which were full access to Everyone. Weird eh? Anyway, I fixed it so I can no longer accidentaly access it.
