Looks like both drives are bad. Have anybody tried simultaneous replacement of both drives? What problems should I expect? I/m planning to try to replace original Caviar Greens WD20EADS-22R6B0 with modern Blue drives WD20EZRZ.
Thanks, Dmitry
Hi, I don’t think this is possible, I believe that these drives are designed to work only with the type of drives that come inside of the enclosure. But you might want to contact support and see if they have other information.
