whta file system do you have, if file system is NTFS, the best way to destroy NTFS perms is to convert drive to FAT32. or make this:
ry this. Use the file I have attached, save it to your computer and extract it to your d:\
Go to a command prompt and type
takeown D:\(insert name of folder)
This "should" give your current user rights to the folder. Your best doing this with your administrator account.
Hope this works.
