Raid enclosure not showing drives

[danc09]

I recently purchased an Orico 5-Bay USB3.0 External 3.5'' SATA HDD RAID Enclosure with two 2TB green WD drives. Following the instructions it appeared to work in Raid 0 but when I tried to change to Raid 1 I can no longer see the drive. The management software can see the drives but is not showing in windows 7. Can anyone advise how to recognise the drive?

Once you switch to RAID-1, you have to reformat in Disk Management. The old partitions and whatnot get blown away.

Thanks Dave, I re initialized and then reformatted which has worked. I then found that i needed to reformat in exFAT on PC then erase on MAC to be able to access the drive on both machines. A bit of a learning curve for a hacker.
