If you start with one drive, and it is in the left bay, it will be Volume 1
. And when you add the second drive it will become Volume 2
and the right drive will become Volume 1
At this point, when the user accesses Volume 1
, it will appear as if all of the information is gone, but it´s actually on Volume 2
If you switch the physical position of the first drive to the Right
bay, you will be able to access the files.
The reason this happens is:
There are logical volumes
and physical volumes
A physical volume
refers to the actual hard drive.
A logical volume
refers to a formatted partition.
- In Standard mode with one disk , the physical volume is irrelevant and the logical volume is Volume 1 regardless of which bay the drive is in.
- In Standard mode with two disks, the physical location of the disks will determine which volume is which drive. Volume 1 is always on the right and Volume 2 is always on the left.
