So i suggest replacing your cable. Also you might want to check the temperature of the disk using the "smartmontools" utility from freebsd-ports. Harddrives should always be kept very cool < 40 degrees if possible. A higher risk of dataloss and/or lower lifespan could be the result of a higher temperature. Smartmontools can also run self-tests (short or long ones) to check for problems with your drive. Good luck! - Veronica
