Thanks Bruce and Tejun, I have replaced the hot swap drive tray of the drive in question, rebooted and reinstalled the latest version of smartmontools. So far I have read and wrote about 50GB of data to the raid array over the last 18 hours with smartd running and have not seen any kernel error messages. Looks like the interconnect was at fault.

Jon: as Tejun says, the ICRC errors indicate a problem with the data cabling or connections between the drive and the controller. Replug, clean, examine (and perhaps replace) SATA cables and/or connectors. The SMART error log (smartctl -L) might also show entries for the ICRC errors (with timestamps that might be useful). > Bruce, I don't think this is SMART related. Sorry about the noise. > Thanks. Tejun: thank you again, no worries, and definitely no apologies needed!
