I have two Terastation classic models (HD-H1.OTGL/R5). The one currently being used for network backups and archives uses RAID5. I'd like to start full mirroring from the current RAID5 drive to the second drive, but it looks like switching off RAID5 on the first will also destroy all my data. Before I take that chance, I thought I'd ask for some expert advice. Any and all suggestions are welcome. Thanks. - Tony
