Mode 2 is referred to as the Combine Mode or Spanning.
In this mode two drives of various or the same sizes can
be attached to the Disk Jockey on the Drive 1 and Drive 2
ports. The Disk Jockey will then combine the two drives
and mount one hard disk drive on your desktop. Data
written to the Combined disks will be written contiguously
to the first disk and then will be “spanned” onto the second
disk without the user or the computer seeing a delay. This
can be very useful if you would like to back up the contents
of a very large drive but do not have a drive large enough to
hold all of the data. By using spanning you can combine the
sizes of two drives to facilitate the copy.
NOTE - Even if you have different capacity hard disk
drives you can combine them. For example, if one is 20 GB
and one is 80 GB then you can combine them to have one
100 GB volume.
FYI – Spanning is not to be confused with RAID Level
0, or striping (not supported by the Disk Jockey at this
time). In striping the data is divided up and written across
multiple drives simultaneously, in spanning the data is
written contiguously across one hard disk and then spanned
to the next once the first hard disk is completely filled up.
