So after removing the drive I got the "drive balance is not optimal" so I had it optimize and everything was going good. I formatted the removed drive and added it back and had it be used again. Well now after a few days its showing corrupted files again and only on that drive. I have Scanner running on it and its not giving any indication of errors. Should I take this as the drive is failing since it keeps corrupting data? It is a USB drive that I had added temporally until I could get a new internal.
