you must get them in the same state, meaning either erase

the data on both (using the Erase Mode on the Disk Jockey)

or if you would like to mirror a drive that already has data

on the drive, copy the data to the second drive using the

Copy Mode, compare that the data on both drives are exact

by using the Compare Mode and then switch to the Mirror

mode to continue working with the Mirror.

There are a few important details to be aware of when

working in Mode 1, or Mirror Mode:

1. Both hard disk drives need to be Ultra DMA

compatible.

2. If you connect different capacity hard disk drives

you can use Mirror Mode, however you’re only

playing to the lowest common denominator. For

example, if you mirror a 40 GB drive with a 60 GB

drive you will only see a 40 GB volume mounted

on your computer, the remaining 20 GB in this

scenario will not be usable.

3. If one of the hard disk drives fails it will not

automatically restore it. If one hard disk drive fails

simply go back to the Standard Mode (Mode 0) and

use it as a single hard disk drive or make a copy of

the data to a new hard disk drive using Copy Mode,

compare the data on the disks using the Compare

Mode and then resume your Mirror in Mirror Mode.

If a disk fails during operation you will be alerted to the

failure by the following audible alarms:
