8. The new drive is generally automatically mounted. If the drive does not auto mount, enter the
following in the command line, substituting the name of your device instead of /dev/md0, if needed:
sudo mkdir /mnt/raid; sudo mount /dev/md0 /mnt/raid
9. If using a graphical interface in Linux, browse to the location of the drive in File Manager. Otherwise,
use a terminal window to change directories (cd) into the drive.
10. Browse to the /mnt/raid folder (or the appropriate folder name) in File Manager.
11. All recordings are kept in a folder hierarchy matching the channels and recorders you created via the
web interface. Channels are listed by their channel number as video<channel number> (i.e. video1 for
channel 1) and recorders are listed by their recorder number with the videom prefix (i.e. videom2 for
recorder 2).
