HDIO_GET_IDENTITY failed for /dev/sdb. The latest entries look like this:

Apr 22 09:30:04 daisy ata_id[22489]: HDIO_GET_IDENTITY failed for '/dev/sdb'
------------------
I tried running hdparm -tT /dev/sda, but after waiting 5+ minutes for
any command output I cancelled it.
I am rsyncing the data from this system over to another system now,
clearly something is wrong, but I can't tell what.
The system is an older AMD Opteron 180 processor (dual core) 4 GB ram,
RAID controller with RAID 5 set up with 4x 4TB Western Digital Drives.
I rebooted the system day before yesterday, and that's when the timeout
messages started pouring into the log.
when I run tw_cli /c8 show, all four drives say they are ok
