June 22, 20179 yr Hi, one of my two parity drives just failed. It is the first of the two. I pulled the Seagate disk and ran the SeaTools diagnostics program on another PC. The long test came back faulty and it gave me the SeaTools Test Code which helps with the RMA process. I still have warranty on that drive and just issued an RMA request and will send the disk on its way tomorrow. My question now is, do I need to recalculate parity when i am just running one of the two parity disks? Or is it all good and I am just protected against a single drive failure right now? Thanks in advance!
