Hi KoriDas. I'm Greg, 10 years awarded Windows MVP, here to help you.
See if you can Take Ownership of the drive's folders using this handy right click shortcut which installs a Take Ownership shortcut to your right click menu to use in cases like this on files and folders which won't cooperate:
https://www.askvg.com/add-take-ownership-option.... The only warning is to not use it on C:\Windows folder files as this will compromise security.
If that doesn't work then use this same method to Rescue Files when WIndows won't start: http://answers.microsoft.com/en-us/windows/wiki.... It uses the Command Prompt from Repair Mode or Bootable Media when WIndows is not running and cannot block it.
If those methods don't work then the drive may have already failed. You'll need to use your backup.
Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.
