I have an AMD770 system and was able to change out my MythTV recording drive live without rebooting... ie. 1. Stopped backend service 2. unmounted file system 3. Unplugged/Removed drive 4. Installed drive/plugged it in (recognized as same device /dev/sdb, but didn't matter since I use UUID anyway) 5. Formatted XFS, discovered UUID 6. Updated /etc/fstab 7. Mounted filesystem 8. Restarted backend service. Went surprisingly smooth actually. Richard
