Drives may be edited within 010 Editor by clicking 'File > Open Drive...' on the main menu. However, to apply edits to drives or view certain drives in the Open Drive dialog 010 Editor must be run as an administrator first. How to run a program as administrator depends upon which OS you are using:
- Windows - Right-click on the 010 Editor icon and choose 'Run as administrator'.
- Mac OS X - Run the 'Terminal' application and on the command line enter '010editor_sudo'. Alternately you can run 'sudo /Applications/010\ Editor.app/Contents/MacOS/010\ Editor'.
- Linux - Go the terminal and cd to the directory where 010 Editor was installed (for example 'cd ~/010editor'). Then run the command 'gksu ./010editor'.
On Windows, to apply edits to a drive all file handles on the drive must be closed in addition to being an administrator. This is a security feature of Windows but makes it very difficult to apply edits to the drive that the OS is installed on. To apply edits to the boot drive you must first boot from a different drive.
