I've just ordered a replacement (Toshiba P300) that will arrive tomorrow... but the question is, what to do in the meantime? Should I take the drive offline? I suspect so, but would like to double check before taking action. Thanks in advance for any advice. Here are the errors: The following warning/error was logged by the smartd daemon: Device: /dev/sda [SAT], Self-Test Log error count increased from 0 to 1 Device info: ST3000DM001-9YN166, S/N:Z1F13FBA, WWN:5-000c50-04e444ab1, FW:CC4B, 3.00 TB ------------------ The following warning/error was logged by the smartd daemon: Device: /dev/sda [SAT], 8 Offline uncorrectable sectors Device info: ST3000DM001-9YN166, S/N:Z1F13FBA, WWN:5-000c50-04e444ab1, FW:CC4B, 3.00 TB ----------------- The following warning/error was logged by the smartd daemon: Device: /dev/sda [SAT], 8 Currently unreadable (pending) sectors Device info: ST3000DM001-9YN166, S/N:Z1F13FBA, WWN:5-000c50-04e444ab1, FW:CC4B, 3.00 TB Thanks, Allie
