So here's what's going on. I have just recently installed windows 7 for the third time now (following build updates ect). I have two hard drives in my computer, one labeled C:\ where windows 7 is installed and the other labeled D:\ which is the drive in question. When I try to copy a folder from one part of the D:\ drive to another, it simply says, "You need permission to perform this action." Now I've down a bit of poking around trying to find some answers, but nothing has proved to work. I had absolutely no problems when I was using the hard drive first time around with windows 7 (after moving up from Vista) and now the last two times I've reformatted (clean install) I have to Take Ownership of my drive so I can access and use the files. I'm not really sure whats going on and what I should do, I've tried taking ownership (doesn't work) I've tried using an admin account (same), I made sure I had admin rights, I've tried disabling UAC, and I've tried taking ownership of the file I was copying plus the directory I was copying the file too. Basically what I end up having to do is make a new folder, take ownership of the folder (because I can't do anything with the folder until I take ownership because I have no permission to access it), then I can copy my files into the folder. Now to further whats going on here, it also doesn't happen everywhere on my drive. It only happens on folders that I included in my Libraries of my first Windows 7 installation. So I can make a folder on the root of my hard drive and I can do what I feel like. But if I make a folder in, say, my music folder or pictures folder I have to go through this giant fiasco just to use it. Now this is pretty frustrating as reformatting the drive at the moment isn't an option (or I would do that) because its 800GBs full of files and I can't put the files anywhere else. Soooooo any help at all would definitely be appreciated. Thanks!
