Check your SATA or USB cable connecting the disk if it’s loose. If you are using USB 2, try USB 3. Change USB ports. Don’t forget to change USB or SATA cable just to rule out cable issues.

trying to copy node to other drive, but looks like rsync had read error on that piece-expiration db… is there some way to fix or replace that db?
