I have an Areca 1880 with 12 drives. I believe I'm having power issues as occasionally I'll have drives "fail" randomly. There appears to be nothing wrong with the drive based on the SMART data. My guess is a faulty power connector. My question is, every time a drive "fails", it comes back online, but as far as I can tell, the only way to integrate it back into my array is to mark it as "active", and then set it as a hot spare so it starts the rebuild. -- This takes around 20+ hours to complete. In theory, if nothing is wrong with the drive, why do I have to rebuild? Is there a way to get the drive to be integrated back into the array without having to do a full rebuild?
