hi everyone
i have a fileserver with 6 1tb disks
i get the following errors repeated constantly

------------------------------------------------------------
------------------------------------------
ata17.00 exception Emask 0x0 Sact 0x0 SErr 0x0 action 0x6 frozen
failed command: READ DMA
cmd c8/00:30:       tag 14 dma 65536 in
res 40/00:ff:00       Emask 0x4 (timeout)
status {DRDY}

after some googling it's been suggested that it's either a hard drive,
the sata controller or the sata cables.
how do i go about diagnosing and fixing the problem,
any suggestions or guidance would be appreciated.

Hi,
You can also run self diagnostics with smartd, that may tell you more
