June 11, 20206 yr Hello all: I have an issue at the moment. I had some power outages in my house this week and found out my UPS battery had kicked the bucket so the PC would go down. When started, it would automatically go into parity check. last one completed and found/corrected 6k+ errors. But since yesterday, it started doing a Parity sync again and within a few hours, one of my array drives will "unmount" and i get a "Disc1 has read errors" and they continue to increase in count as the sync goes on. Today I stopped the sync, stopped the array (as soon as i do that, the disc returns to normal) and started it in maintenance mode. Currently running a extended smart test on the drive as a short one passed but some of the posts Ive read thru suggest to do an extended one. What should I look into or do next. Ahead of time, Im fairly new to Unraid. do-minion-smart-20200610-2311.zip

Ironically, it was working fine for months before the power outages. I wonder if the USB drive goes offline at some point for some reason
