I have searched for this quite a bit, to no avail. I recently purchased an Iomega Value Series 1TB external drive. This drive is set up as a JBOD from 2 500GB drives. Before I bought it, I found two posts stating that this drive can support RAID 1, but I cannot, for the life of me, figure out how to do it.
I did since note that one of the posts was removed, but the other, which is a comment on amazon, seems to be written by a knowledgable person.
Long story short, I now have the drive, and can't seem to find any configuration options, software, utilities, nada. Does anyone know if anything can be done to the current configuration, or if I can make the controller change the setup to RAID 1? Even if i am stuck with JBOD, is there any way to see how it is configured? Iomega support is useless.
Well, I think I know.
I had about the same trouble. I took a raid1 config with 2 2 tb hd's. Suddenly onde of the drives became a jbod.
I found out that that became of several partitions on the drive and raid1 assumes 1 partiotion.
So the solution should be: delete any partition just in windows, than delete all partitions and format the whole drive as 1 partition.
Connect the drive to a second sataport and now the drive should mirror himself to the bootdrive.
