Works fine for me without doing a pool per USB HDD.  If bacula can't
find the old volume, it makes a new one with the same name, which
seems a little odd, but works OK.  Options I'm using in the SD device
config:

Device {
  Name = FileStorage
  Media Type = File
  Archive Device = /backups/bacula
  LabelMedia = yes;                   # lets Bacula label unlabeled media
  Random Access = Yes;
  AutomaticMount = yes;               # when device opened, read it
  RemovableMedia = yes;
  AlwaysOpen = no;
}

One trick: I use /backups as the mountpoint, with the "bacula"
directory on each volume as the archive device.  So if there is some
problem and the USB device won't mount, bacula refuses to perform the
backup instead of writing to the root FS.
