I accidentally removed all the access permissions from my external USB drive, after I had already taken FULL ownership of the drive, and now it shows me the drive icon and letter "E:", but states that Access is Denied when opening. Even the "Security Tab" is gone from the drive's properties. I was trying to change permissions to include inheritable ones, and I hit the wrong button to remove I think(I was stupidly moving too quickly through all the options, my fault), and after that I was no longer able to acces the drive. I have thousands of files on this drive!!PLEASE HELP, ANYONE?? The drive still shows up within Windows Explorer as E:, and Disk Management shows it as a Healthy (Primary Partition).
UPDATE: Found the fix, thank you lord!! I tried going into Safe Mode just in case, and it worked! Go into Safe Mode, and login with an administrator account. From there you will be able to right click on the drive and have the "Security Tab" working again, where you can take ownership and add permissions back!!
