So I have a 3-drive raid5 array, and I had one of the drives go into "error" status, and the other two be flagged as degraded. This is a hardware raid controller on a NVIDIA mobo. The problem occurred immediately after reboot after installing an NVIDIA Sata Controller update through windows update. (I have since rolled this driver back, error persisted)
I assume, that to fix this I simply need to reformat the one individual drive that seems to have "error" or even just run "clear disk" from the raid controller, and then select "rebuild". However, this is my first time with a raid error, and I don't want to botch it all up and loose 2TB of data! So please let me know if this is a terrible idea or if there is another way I should do it.
