whats mean kernel message "Non Fatal error on ida/c0d0" ?

[Sir Hamacker]

People, necessary of the aid of you.
I have here in a customer, one compaq prosignia 200 with one an Array
SCSI(SL2-Controller using Raid 0) that always after the of backup job
that I programmed entire home system for the 20:00, starts to give
the follow error messages bellow (at bottom). 
The question is: It will be that the Array beating the
boots(potrtuguese expression), ops in english : Will be that this
disk this in the end of its life?
Or there are some conflict between controller Array versus dat unit?
Remembering that the Array will count 5 disks of 2GB (therefore Raid
0 without reduncy), and ja has one 6 years of age. However the
controller is newer. 

I need to know if already he is in the hour to change my disks, or my
micron badly is configured. 

Messages logs to init a controller, thats ok :
