I had an 8 TB External USB disk plugged into the system, that I had been
using for additional space for backups, I was under the impression that
sda, sdb, sdc, and sdd were the four disks on the raid controller card,
but after unplugging the usb drive when running hdparm I am getting this:

[root@daisy dev]# hdparm -tT /dev/sdb

/dev/sdb:
read() hit EOF - device too small
 BLKGETSIZE failed: Inappropriate ioctl for device
BLKFLSBUF failed: Inappropriate ioctl for device
[root@daisy dev]#

------------------------------------------------------

the 3ware controller shows all four disks still online with a status of ok:

I'm still trying to find the exact smartctl command syntax to make it work.

Does this give you what your looking for?
