In Windows 7 I managed to really mess up my D: drive's permissions. For some reason, changing the sharing permissions for network took away local permissions and even stranger, these permissions held even across XP and now Vista.
I'm in Vista now and I can't access a folder on my second drive (just storage, no programs). I want ANYONE to be able to read this drive locally, but I can't change permissions on it and I can't get in and although UAC comes up it still won't let me in.
I'm using an administrator account (the only account on my PC) so I'm not sure why it's denying me, I should be able to access anything as admin.
EDIT:
After restarting and disabling UAC, I was able to change the permissions on most of the drive to full access.
HOWEVER, the idiot thing denies me access to some folders completely:
Remember. I'M AN *********** ADMINISTRATOR! Admins should have FULL CONTROL! WTF?
Never mind, Windows 7 apparently set the User to a garbage value (just a bunch of random numbers) and reclaiming ownership of the folder re-enabled it. However, there is one folder containing one file that Windows still cannot see.
"D:\Software\Windows Software\Games\Wolfenstein: Enemy Territory refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location."
I know FOR A FACT that this file exists because I can access it in Linux just fine. Considering it's just a <100MB EXE I could probably just copy it out and back in using Linux, but it's still ridiculous that Vista refuses to see something that an imperfect, reverse-engineered implementation of NTFS sees just fine.
