thanks for the feedback. In addition to deleting the 2nd plot, I also deleted the shell of the optimization file... actually did that first. but alas, it does seem likely that stopping this process caused my issue. Still going along at 13,100 bad files found. I really hope this drive isn't dead because it will take forever to recoup that money from Burst mining.
Anyone have an idea for a good disk repair utility if the windows one i am running doesn't work?
