One of the drives I pulled out and that tested good I put into a USB
external drive to use for temporary backup. I was using it today to
backup my RAID mirrors offline and I get an email from smartctl daemon.
The following warning/error was logged by the smartd daemon:
Device: /dev/sdf [SAT], ATA error count increased from 0 to 813
TOSHIBA HDWD120, S/N:58NYHDVCS, WWN:5-000039-fd4db8021, FW:MX4OACF0, 2.00 TB
I ran a smartctl -t short test and I attached the output as a log file.
