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. shadrock
