I have smartmontools performing regular short and long scans but I will run 
the tests immediately and send the output of smartctl -a when done. 

Note I'm getting similar errors on sdc too (as in 5 minutes ago). 
Interestingly the SMART error logs for sdc and sdd show no errors at all. 

ata3: command timeout
ata3: no sense translation for status: 0x40
ata3: translated ATA stat/err 0x40/00 to SCSI SK/ASC/ASCQ 0xb/00/00
ata4: status=0x40 { DriveReady }
sd 3:0:0:0: SCSI error: return code = 0x08000002
sdd: Current [descriptor]: sense key: Aborted Command
     Additional sense: No additional sense information
Descriptor sense data with sense descriptors (in hex):
         72 0b 00 00 00 00 00 0c 00 0a 80 00 00 00 00 00
         00 00 00 00
end_request: I/O error, dev sdc, sector 260419647
raid5:md6: read error corrected (8 sectors at 260419584 on sdc1)

Will post logs when done...
