Increasing bad sectors, unable to run a SMART test
I have two refurbished Seagate drives in my DS423+. For a while I've gotten notifications saying the number of bad sectors has increased on drive 1, and in the last few days it's started increasing on drive 2. I tried running a SMART test on drive 1, and it said it would take 1100 minutes, but it finished immediately and just says "attention required." I ran a SMART test on drive 2 overnight, and it still says it's healthy.
Does this mean drive 1 is about to fail? Are they both failing? This is the first NAS I've owned, what's the best course of action here?
