So I rebooted, tried several cables, data and power, tried different data ports and the reallocated sector count just kept climbing, and then a udma error started popping up. I swapped this with another ssd in the machine, and it still had issues while the other ssd was fine, so I think it’s safe to assume it’s the drive failing.
I pulled the drive from the pool and am running the pool with one drive. If I stop and add a new ssd (240gb vs the current 256gb) can I just start it and do a scrub?
