boot error ata5.01

[Bonechilla]

For some odd reason when i boot into ubuntu it lags and shows a repeating couple of lines that I've found to be error codes. I found on the forums that it was related to the Harddrives so i decided to format any partition that was ubuntu or a swap however after bringing over all of my data onto the ubuntu partion and reformating everything else it hasn't seemed to fix anything. Can anyone deliver advice?

i get codes such as below:

ata5.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action
ata5.01: failed command: READ DMA
ata5.01: c,d c8/00:08:00:00:00/00:00:00:00:00/f0 tag
res 40/00:03:00:00:00/00:00:00:00/a0 Emask
ata5.01:status {DRDY}
