Before rebooting the system try 'mount -a' and fix any error before rebooting. If 'mount -a' does not conplain, you should be fine; if an error were to happened, you can always recover. Also, keep an unmodified copy of your fstab file before modifying it. > 2. Will I be able to read adn write to the added drives? > Looks like it, trying your changes will be the only way to tell. P.S. If you are that afraid of messing around, having a test environment is clearly needed. -- John Doe
